9 Best Rated Air Purifiers and Humidifier Combo – In-Depth Reviews

C lean, healthy air is essential to create an ideal living environment. Woefully, it is impossible to enjoy this perk without the use of specialized devices as our homes, no matter how hard we try to keep them clean, are plagued by health-threatening pollutants like volatile organic compounds, mold, dust mites, and even bacteria.

This causes respiratory issues to arise in healthy individuals and it puts those who suffer from allergies or asthma in a truly unpleasant situation as their afflictions act up because of the improper habitat. If the situation wasn’t bad enough on its own, there’s the humidity level issue to worry about as well. As the seasons change, so do environmental conditions, and the dry air that is present in wintertime predisposes you to colds, nosebleeds, dry skin, and chapped lips. Even worse, it predisposes you to viral infections that could have serious repercussions.

An experiment from Yale researchers points out the issue of low humidity and viral infections best, showing that people are more likely to get sick and have serious, severe health complications during winter months when the air gets drier. The research indicates that it’s not the temperature that needs to worry us since test subjects – genetically modified rats that resist viral infections as well as we do in this case – responded good or bad only when shifts in humidity level occurred. When air moisture levels were within healthy parameters, the immune defense system of the subjects resisted the influenza A virus, while in low humidity conditions, the outcome differed for the worst.

To keep the situation under control and keep air purity and humidity within safe parameters, you would normally require the help provided by 2 different devices – the air purifier that tends to remove airborne pollutants, and the humidifier that tackles low humidity by outputting moisture. But why should you make two separate purchases when you could fix the issue with a single device?

Although the market isn’t saturated yet and there is room for improvement, there are more than enough qualitative air purifier and humidifier combo machines that are sure to serve you properly, creating that healthy indoor environment you always dreamt of.

If you’re only interested in the moisture-enhancing function, then you’d better check out these large room humidifiers that are specialized in this specific task.

Low humidity might be an issue during winter, but when summer comes, moisture levels tend to rise. To prepare for the occasion, get yourself a dehumidifier and make sure that mold won’t become an unwelcome guest in your home.

1. Brondell O2+ PR50 Revive

  • Room coverage: 627.5 sq. ft.
  • Filter media: Granulated carbon filter, off-gassing reduction filter, dual True HEPA filters, humidifier filter
  • Purification efficiency: 99.97%
  • Water tank capacity: N/A
  • Humidity output: 350 milliliters per hour
  • Speed settings: 4
  • Noise level: 36 – 64 dB
  • Dimensions: 15.6” x 12.5” x 19”
  • Weight: 24 lbs.
  • Warranty: 3 years

The Brondell Revive outclasses competitors not only because of its impressive efficiency but due to the range of features it integrates and the low-cost maintenance it involves. To give you a taste of just how great the Revive is, know that it produces a whopping 3 air changes per hour in a space of up to 627.5 square feet. On the other hand, our runner-up, the Sharp KC-850U Plasmacluster, is recommended for smaller areas of only 254 square feet tops. It clearly surpasses its direct competitor even when it comes to CADR ratings since it’s awarded a 230 CFM score, while the runner-up stands at an average of 164 CFM.

Dual Suction and Dual Filtration

Dual intake for superior airflow:

If you were as surprised as we were by the ability of this air purifier and humidifier to handle spaces upwards of 625.7 square feet in quite a prolific manner, producing 3 ACH, it will all make more sense knowing that it features dual intake. What this implies is that better airflow is created while more air is pulled inside. So it’s twice the air at half the time, all due to a single difference in design that makes it superior even to other large space devices like the bblüv Ümi that aren’t as rapid in their performance nor as efficient when it comes to purification and humidification.

Dual True HEPA filtration for unparalleled air purification:

The high air pollution reduction score of 99.97% this Brondell model flaunts comes from the multiple effective filter media it uses in its operation, specifically:

  • Granulated carbon filter: Specializes in trapping and removing harmful gases, VOCs, and odors.
  • Off-gassing reduction filter: Removes VOCs that are at fault for the “sick house syndrome” and invisible substances the likes of formaldehyde.
  • Humidifier filter: Works similarly to an air washer. It traps air particles like dust, taking them out of the air for good.
  • Dual True HEPA filters: The two HEPA filters it integrates capture airborne particles down to 0.3 microns with a high efficiency rate of 99.97%, ensuring cleaner air indoors than you ever witnessed.
Effective Evaporative Humidification

It uses the self-regulating evaporative humidification method to raise moisture levels indoors in the most healthy, natural manner possible. Using the specialized humidification filter through which it passes the air, the Revive evenly distributes the moisturized air throughout the room instead of focusing only on the area in its proximity. Dense vapor pockets won’t be formed as a result, and you won’t find puddles on furniture pieces that are next to the device either. Instead, it outputs 350 milliliters of moisture per hour at a steady pace, an ability that steam vaporizer or impeller humidification units can’t brag with.

Mention-Worthy Features and Highlights
  • Puts at your disposal 4 operating modes to pick from, including the Auto mode that is a “set and forget” type since the device will adjust fan speed and humidification rate according to air purity and humidity readings it picks up in real-time.
  • Humidity indicator and air quality indicator to keep you aware of indoor conditions at any given moment.
  • Automatic shut-off timer lets you set the precise running time to save money on running the device.
  • Use the Sleep mode when you want to take a much-needed nap but you don’t want to turn off the unit.
  • Filters require replacement every 4 to 12 months. The filter media isn’t expensive either, these two aspects combined ensuring that maintenance won’t be a costly affair.
  • When filter replacement is due, the indicator light turns on to let you know. So, you won’t have to keep an eye on the calendar to remind yourself of this upkeep task since there’s an integrated reminder for this specific chore.
  • Intuitive touch control panel guarantees a user-friendly experience so that even first-time owners won’t have trouble figuring out how to operate the product.
  • Upholds a relatively quiet performance regardless of the fan speed or running mode you pick. Depending on your selection, it will produce from 36 to 64 decibels tops.
  • One of the more discrete options since it doesn’t take up much space. Perfect for small living accommodations and offices – measures 19 inches in height by 12.5 inches in width by 15.6 inches in depth.
  • Backed against defects for 3 years. During this period, repairs are granted for free by the manufacturing company.
Performance Tests – Expert’s Remarks

To accurately review and rank the products in our top, we had to test them first, obviously. From all the air purifier humidifier units we rounded up, the Brondell O2+ PR50 Revive was the one that scored highest during all testing trials. Let’s see what performance tests we put the device through and how it scored to give you a better understanding of why it’s worth the investment:

  • Removal of allergens: 100% efficiency – Score 10/10
  • Removal of odors and chemicals: 100% efficiency – Score 10/10
  • Removal of asthma triggers: 100% efficiency – Score 10/10
  • Removal of tobacco smoke: 98% efficiency – Score 9.8/10
  • Humidity level increase: 100% efficiency – Score 10/10
To test the Brondell Revive, we had to use another two devices for monitoring the progress, namely an indoor hygrometer and an air quality monitor. We tested the room for both stats before and after running the hybrid device, comparing stats to see how big of a difference the Revive actually made in terms of humidification increase and air quality improvement. Before turning the air purifier humidifier on, the humidity level was at a low level of only 33%, while air purity was extremely low because of PM2.5 pollution and cigarette smoke odors. We ran the unit for 8 hours straight with both functions turned on. After its operation, the humidity had risen to 49%, and air quality was within normal parameters.

Marcus Mackay

  • Fitted with dual True HEPA filters that enable it to remove 99.97% of particles down to 0.3 microns

Clean and comfortable air is what the Revive promises and delivers. A true hybrid product that clears the air of up to 99.97% of polluting particles down to 0.3 microns in size, while also taking care of the demanding task of amplifying indoor humidity by adding up to 350 milliliters of moisture per hour, it is a reliable product that rules over the market for all the right reasons. Add to its performance the fact that it produces 3 air changes per hour in a vast space of up to 627.5 square feet, and it’s understandable why the Brondell Revive takes the #1 spot.

2. Sharp KC-850U Plasmacluster

Check Price at Amazon

  • Room coverage: 254 sq. ft.
  • Filter media: Active carbon filter, HEPA filter, humidifying filter
  • Purification efficiency: 99.97%
  • Water tank capacity: 7.7 pints
  • Humidity output: 7 – 10 pints per day
  • Speed settings: 3
  • Noise level: 23 dB

  • Warranty: 1 year

Ready to not just catch airborne particles like dust, residue, and microorganisms, particles that present an immediate risk to the wellbeing of people who experience the ill effects of asthma or sensitivities, however ready to give solidness with regards to another vital air quality characteristic, which is dampness, the Plasmacluster is a reliable partner in the modern household.

Utilizing the latest technologies and releasing ions into the air to improve its cleanliness, all while putting 3 filter media at your disposal to guarantee balance as far as purity and moisture go, it was an easy pick for our top. Besides helping create proper living conditions, it makes for a quite nice addition to the room you put it in because of its thin outline, clean white housing, and the cutting edge feel its electronic controls offer.

Air Cleaning Performance

With a high proficiency of up to 99.97% with regards to handling airborne particles, it is anything but difficult to perceive any reason why this is our best pick. Among the most hazardous contaminations it handles are incorporated microbes, smells, germs, growth, particulates, dust, and residue. It provides an automatic operation that we will cover instantly, yet it likewise lets you manually pick the speed at which it cleans the air – you get the chance to choose from 3 different fan speeds.

  • Technology: Plasmacluster
  • HEPA filter: Yes
  • Ion release: Yes
  • Efficiency: 99.97%
  • Minimum particle size: 0.3 microns
Humidity Increase Performance

The trait that helps it double as a humidifier in addition to an air-purifying device is the humidifying filter it comes with. As the tank which holds the water that is going to be released into the air to moisturize it has a hearty 7.7-pint capacity, you needn’t worry about refilling it too often either. You even get to choose whether or not you want its humidifying program to be active so that when summer comes and environmental conditions stabilize, you won’t consume extra power uselessly. You can do so by choosing between the “clean air” and the “clean air and humidify” options.

Check out these ultrasonic humidifiers too if you want to benefit from a rapid and efficient humidity increase indoors.

Automatic Operation

As it includes a dust tracking sensor, it even gives a solid automatic operation that takes the hassle out of using it. The perk this function gives is that it doesn’t expect you to choose a particular operational level contingent upon the air contamination level right then and there, monitoring indoor conditions to begin, stop, and alter speeds automatically as indicated by what readings the sensor gives.

Other Mention-Worthy Details
  • Produces 23 decibels on the Low setting, 34 decibels on the Medium setting, and 51 decibels on the High setting.
  • Impressive CADR evaluations – 164 for dust, 174 for dust, and 164 for smoke/tobacco.
  • The power cord measures 8.3 feet, barring the requirement for an extension cord.
  • Complies to UL/cUL safety standards – you don’t need to stress anything may occur on the off chance that you run it when you are away from home.
  • When it enters standby mode, it draws just 0.3 watts.
Energy Efficiency

The most ideal approach to portray its effectiveness as far as power consumption is to bring up the fact that it is Energy Star rated. Perceiving how this prestigious certification is just given to appliances and devices that draw significantly less power than other entries in their niche, is all the proof you need to be sure of the fact that it won’t cost a fortune to run it.


There are 3 filter media you should tend to, an activated carbon media, HEPA media, and a humidifying filter. It even features a micron mesh pre-filter that removes small-sized airborne particles to make the job of the main media less demanding, expanding purification efficiency. The uplifting news with regards to upkeep is that you won’t really need to monitor the filters yourself as you will be announced by the clean filter indicator light when your attention is required.

Activated carbon filter:
  • Washable and reusable, its replacement cycle coming once every 5 years.
  • Serves the purpose of deodorizing the air.
  • Measures 15.7″ by 9.7″ by 0.39″ and weighs 0.31 pounds.
HEPA filter:
  • It requires replacement only once every 5 years.
  • Serves the purpose of removing dust from the air.
  • It measures 15.7″ by 9.7″ by 1.5″ and weighs 0.48 pounds.
Humidifying filter:
  • It needs to be replaced once every 2 years.
  • Serves the purpose of humidifying the air.
  • It measures 7.5″ by 8.9″ by 1.2″ and weighs 0.15 pounds.

If it were to bring up an imperfection, this would be it – the short 1-year warranty on parts and labor provided for it. Other entries are covered and promise to be repaired for nothing out of pocket for longer time ranges. However, everything considered, the KC-850U is still deserving of its spot as it conveys a general unbeatable performance, for the moment at least.

  • Uses True HEPA filtration to remove up to 99.97% of impurities as small as 0.3 micrometers from the air
  • CARD rated 164 for dust removal and 174 for pollen removal
  • Energy Star certified for its low power draw and overall operational efficiency
  • Features a washable active carbon filter that helps remove nasty odors for fresher air indoors

  • It is too loud when set on the highest speed setting
  • Expensive filter replacement


With the amazing ability to release up to 10 pints of moisture per day and boasting a high efficiency of up to 99.97% when it comes to the elimination of impurities from the air, the Sharp KC-850U can maintain a healthy habitat for you to live in.

3. Boneco H300

  • Room coverage: 540 sq. ft.
  • Filter media: Pre-filter, HEPA filter, textured evaporated mats
  • Purification efficiency: 97%
  • Water tank capacity: 1.18 gallons
  • Humidity output: 350 grams per hour
  • Speed settings: 6
  • Noise level: 28 dB
  • Dimensions: 11” x 11” x 18.3”
  • Weight: 12.1 lbs.
  • Warranty: 2 years

The H300 comes as a much-needed replacement for the Boneco W200 air washer we previously featured in our top. While the W200 is still a worthy purchase, hands down, it’s not as efficient as this upgraded model. Both are combo units, which means that they clean the air while amplifying moisture levels. However, the W200 works more like an air washer, while the H300 is a true hybrid – an air purifier that has an extra humidifier function through the spinner. So, if you’re looking for some serious action when it comes to allergen removal, the H300 is the better option.

Suffering from allergies and you want to keep the symptoms at bay? Then look into an air purifier for allergies and asthma since these devices are specifically tailored to clear the air of any allergy triggering particles.

Just like the W200, the Boneco H300 is recommended for areas up to 540 square feet in size, which makes it the best hybrid humidifier/air purifier for large rooms. Other aspects that these two products have in common include:

  • Both boast a 1.18-gallon or 4.5-liter capacity for their respective water tanks.
  • Both output 350 grams of moisture per hour when used at their peak setting.

Now let’s move on to the differences that ultimately make the H300 the better option. Unlike the W200, it features multiple air filtration media, namely a pre-filter, a HEPA filter, and textured evaporated mats. This is why it is the better choice for air contamination removal. It is even CADR rated (under 90 m3 per hour), while the W200 isn’t. On its quietest setting, the H300 is indeed a bit noisier than the W200 since it makes 28 dB. However, it draws significantly less power when it runs, precisely 9.6 watts on level 6, the peak speed it boasts.

When the water base is empty, it automatically turns off. Moreover, the LED light turns red so that you know at a glance what the issue is and handle it. To control it, you either manually turn the control knob or use the Boneco app on your phone. You can pick between the 3 operating modes – purifier, humidifier, or hybrid. This isn’t where the perks end since there are a few other mention-worthy highlights the H300 impresses with, namely:

  • On/off timer that gives you control throughout the device’s operation beforehand. This feature helps save on running costs.
  • Child safety lock switches the control fully over the app. This way, even if the kids start turning the knob and playing with the hybrid air purifier humidifier, they won’t be able to change settings.
  • It features a fragrance container where you can add essential oils to bask in an aromatherapy session whenever you feel stressed and want to relax a bit.

The design is pretty much the same, which is a plus since this staple Boneco look is quite a success among customers who care about the pieces they add to décors. The H300 measures 11 inches in length by 11 inches in width by 18.3 inches in height, so it makes for a viable option even for small condos. Since it weighs only 12.1 pounds when it’s empty, you will easily move it from room to room on your own. To end on a high note just like we have begun, we mention that the accompanying warranty for this product is 2 years long. During this period, repairs are handled free of charge.

Boneco W200 Rating:

*Although it might seem that the air purification of the H300 isn’t all that impressive, keep in mind that this is an actual air purifier and humidifier, while the W200 is only an air washer. Therefore, the H300 functions significantly better when it comes to air quality improvement.

  • A 3-in-1 device that gives you a run for your money – use it as a purifier, a humidifier, or a hybrid between the two
  • Install the Boneco app on your phone and you will conveniently switch through settings and select the running modes and predefined profiles you prefer
  • Child safety lock function keeps the kids from tampering with the settings of the hybrid unit
  • Relax your mind and body through aromatherapy by using the fragrance container of the H300 to disperse essential oils into the air



Boneco steps up their game through the release of the H300, a model that gives the Sharp KC-850U Plasmacluster a run for the money. Perfect for large spaces of up to 540 square feet and highly effective in its task of purifying the air thanks to the multiple filtration media it uses, all while delivering on its promise to raise indoor humidity in the process too, it’s a new release that has really taken the market by storm.

4. Hestom TKJ400F-A5

Check Price at Amazon

  • Room coverage: 215 sq. ft.
  • Filter media: High-density mesh pre-filter, H13 True HEPA filter, activated carbon filter
  • Purification efficiency: 99.97%
  • Water tank capacity: N/A
  • Humidity output: N/A
  • Speed settings: 4
  • Noise level: 35 dB
  • Dimensions: 11” x 11” x 25.6”
  • Weight: 18.5 lbs.
  • Warranty: 1 year

What makes this Hestom model a standout is the large area coverage – it can run efficiently even in spaces of up to 1,200 square feet. However, when you use it at its peak from this point of view, it will produce only 2 air changes per hour. If you want to benefit from optimal performance on its part, you should use it for a room that measures approximately 215 square feet since it will produce 5 air changes per hour under this circumstance.

What you are sure to appreciate the most stands in the air quality index that displays air purity levels in real-time. This gives you better control over its operation since you can adjust the settings of the purifier according to current pollution conditions. Speaking of settings, when it comes to the speed with which it pulls in the air to clean it, there are 3 options to pick from.

Want to check air quality in the rooms where you’re not using this combo unit too? Then get yourself an air quality monitor and walk around the house to see just how well air purity levels fare.

When it comes to the humidifying function, this smart unit detects moisture levels and automatically adjusts the humidity output to uphold optimal levels at all times. When the tank is full, expect it to run uninterrupted for about 7 hours (or more, if humidity levels aren’t that low).

Considering that it uses 3 stages of purification, even employing an H13 HEPA filter in the process, an estimated 99.97% of impurities will be removed from the air you breathe. The filters need replacement only every 6 months if you run the combo unit continuously, so there won’t be a lot of money spent on upkeep. To save power, it features a timer that you can set for 1, 2, or 4 hours.

Seeing how it only produces 35 dB, you can comfortably sleep in the same room with it. Since it weighs only 18.5 pounds and doesn’t take up much space either, you can move it from room to room to benefit from its operation wherever you’re sitting at that moment. Lastly, we must say a word about the warranty – the product is backed for 1 year, and repairs won’t cost you a cent within this period.

  • Can clean the air in a room or space measuring 1,200 square feet tops – in this scenario, it will produce 2 air changes within the hour
  • The air quality index display keeps you informed regarding air purity levels so that you pick the right operating modes for the unit
  • You can set the timer function for 1, 2, or 4 hours – when the time passes, it automatically turns off
  • On a full tank, the humidifier function can run continuously for up to 7 hours

  • Because the air intake is placed in the back of the unit, you won’t be able to place it against the wall, for example
  • At the highest operating speed, it makes a hefty amount of noise


While ideally, you should use it in spaces of up to 215 square feet since in this situation it produces 5 air changes per hour, this heavy-duty model works for larger areas of up to 1,200 square feet too, the difference being that it will only change the air twice within the hour. So, if you have a large room or area where you want to benefit from clean and humidified air, this Hestom product is your go-to.

5. Venta LW15 Airwasher

Check Price at Amazon

  • Room coverage: 200 sq. ft.
  • Filter media: Filter-free design
  • Purification efficiency: Over 99%
  • Water tank capacity: 1.4 gallons
  • Humidity output: Approximately 0.64 pints per hour
  • Speed settings: 2
  • Noise level: 22 dB
  • Dimensions: 10.2″ x 11″ x 12.2″
  • Weight: 6.6 lbs.
  • Warranty: 10 years

As far as humidity increase abilities go, it is recommended for use in spaces of up to 200 square feet, while its performance as far as air filtration makes it reliable for use in spaces of up to 100 square feet. Its air cleaning abilities make it somewhat less performing than some of our entries, but the way that it doesn’t produce ions, ozone, or white dust compensates for its small flaw as it is safer and more qualitative.

It is capable to tackle airborne contaminations down to 0.3 microns too, another plus that not a lot of devices offer. Besides, the cool evaporative technology it depends on awards a viable way to increase dampness levels indoors that is safe enough to make it usable in the nursery.

As you can see, it features a quite generously sized 1.4-gallon capacity tank that won’t require refilling all that often. When set on its low fan setting, it produces only 22 decibels, while on the high fan speed, it produces 32 decibels. Another mention-worthy aspect is the fact that it consumes little power to run, less than 10 watts to be more specific.

It automatically shuts off when the tank is empty to prevent overheating, and it features a LED indicator that lets you know when this maintenance task is required of you. There are no filter pads to change, which reduces operational and maintenance tasks for it. Additionally, it is suitable for all water hardness levels, so it is one of the least pretentious devices you will encounter.

  • Can remove airborne particles as small as 0.3 micrometers in size
  • Able to provide moisture increase for areas of up to 200 square feet and air purifying capabilities for areas of up to 100 square feet
  • Lacks of filter pads makes maintenance easier and reduces upkeep costs
  • A low water indicator lets you know when it is needed to refill the tank to eliminate guesswork

  • Automatic shut-off when it runs out of water tends to fail at times
  • A few users complained about customer support services


Very easy to use, the Venta LW15 provides air purification capabilities without actually using a filter, which makes it all the more desirable as upkeep costs are minimal and there isn’t much in the way of maintenance work involved with it.

6. Envion FS200

  • Room coverage: Medium to large-sized rooms
  • Filter media: HEPA filter
  • Purification efficiency: 99%
  • Water tank capacity: N/A
  • Humidity output: 2.2 gallons per day
  • Speed settings: 3
  • Noise level: N/A
  • Dimensions: 9″ x 11″ x 26″
  • Weight: 10.6 lbs.

What sets it apart from all of our other entries is the fact that it doesn’t only add moisture to the air and clear it of impurities, but it can be used as a fan when the weather is too hot and you want to cool off, and as a heater during chilly autumn and winter days. In fact, it puts 3 independent control settings at your disposal to pick between, more precisely Heater, Heater & Humidifier, and Humidifier & Fan.

It can output up to 2.2 gallons of moisture per day, the cloth wick it uses for the evaporative humidification process being washable and reusable to spare making additional purchases. When the tank it features is low on water, the LED indicator light activates to let you know that refilling is needed.

For safety purposes, when the tank does empty, the sensor it features causes it to automatically shut off. Another safety feature is the tip-over sensor that makes it turn off completely when it is knocked over to prevent any unwanted incidents. There are 3 fan settings and 3 heating power levels that you can pick between to customize the atmosphere it helps create.

As the filter it uses is a HEPA-type model, it effectively removes pollen, dust, smoke, dust mites, and pet dander from the air, among other things. Furthermore, it provides up to 3 air changes per hour to ensure you are constantly breathing in fresh, clean air that benefits your health instead of affecting it.

Check Price at Amazon

  • Room coverage: 219 sq. ft.
  • Filter media: Prefilter, activated carbon filter, HEPA filter
  • Purification efficiency: 99.9%
  • Water tank capacity: 1.9 liters
  • Humidity output: 150 milliliters per hour
  • Speed settings: 3
  • Noise level: 30 dB
  • Dimensions: 7.67” x 7.67” x 21.85”
  • Weight: 5.73 lbs.
  • Warranty: 6 months

While the product’s performance is worth the praise on its own, the detail that stands out the most with this Afloia model is the unique design. The humidifier module that is placed on top of the air purifier is actually powered by it and provides clean humidification through cold evaporation. When you don’t want to benefit from the moisture release part of the unit’s capabilities, all that you have to do is separate the module from the purifier.

Keep in mind: Take into account that the humidifier section doesn’t word separate from the air purifier one. So, only remove the module when you consider that moisture increase is not needed.

In terms of performance, we like that this is a reliable option for medium to large-size spaces:

  • In a room of up to 219 square feet, it produces 5 air changes per hour.
  • In a space measuring 438 square feet tops, you can count on it to produce 2 air changes within the same 1-hour period.

To make sure that no particles escape its performance, it passes the air through 3 filtration stages, even using a HEPA filter in the process to make sure that the tiniest of particles are trapped too. Don’t worry your mind about remembering when you ought to change the filters because the nifty indicator lights up when filter replacement is due.

The tank can hold up to 1.9 liters of water, and the mist output released by the unit is 150 milliliters per hour. A feature that comes in handy for those who have trouble sleeping and feel the need for a soothing light in the room is the warm night light with 2 brightness levels. There are 3 controls in regards to fan speed, on the lowest producing only 30 decibels.

It even features a timer that you can set for 2, 4, or 8 hours. When your chosen time passes, the unit will automatically shut off. In regards to the warranty, it is 6 months long. This isn’t impressive but the company respects customers and follows through with repair requests within this period.

  • Filter replacement indicator lets you know exactly when this routine maintenance task is due
  • You can detach the humidifier if you are only interested in benefitting from air purification
  • The warm night light with 2 brightness settings soothes you to sleep
  • Rated at only 23 watts, it won’t draw much power when it runs

  • Not very impressive when it comes to its humidity raising capabilities
  • The water tank cover isn’t very secure


Likely the most interesting product we reviewed due to its ingenious design, this Afloia model is bound to receive praise since it’s so well thought-out. The humidifier section is detachable and it doesn’t render the air purification part useless, so you can either use it as a classic air purifier or combo unit and benefit from humidity increase too.

8. bblüv Ümi

Check Price at Amazon

  • Room coverage: 538 sq. ft.
  • Filter media: Filter-free design
  • Purification efficiency: N/A
  • Water tank capacity: 1 gallon
  • Humidity output: 280 milliliters per hour
  • Speed settings: 3
  • Noise level: 35 dB
  • Dimensions: 5.7” x 5.7” x 19.8”
  • Weight: 3.65 lbs.
  • Warranty: 3 months

While it might not rank the highest, this shouldn’t take away from the merits of the bblüv since this is a 3-in-1 product that is more than efficient at everything it does. The 3 functions it comprises are humidifier, air purifier, and aroma diffuser, so you can see why a lot of people have taken an interest in it. The aroma diffuser comes in handy for those who enjoy relaxing with aromatherapy (it even works as an essential oil diffuser).

To call it soothing would be an understatement, especially considering that it even features a night light that changes colors. This makes it perfect for the nursery or a child’s room, even for adults who have trouble sleeping. It is suited for spaces of up to 538 square feet, so it’s likely going to handle even purifying the air in your large living room.

  • When discussing its humidification capabilities, considering that it features a large 1-gallon capacity tank, even as much as 28 hours can pass between refills. The 360-degree rotary output ensures that the cool mist is released throughout the whole room concomitantly for optimal results.
  • An aspect that impresses is that it doesn’t use filters for air purification. Therefore, you won’t spend money on upkeep at all. Instead, it uses ionization, emitting anions to capture and eradicate the polluting particles from the air.

There’s even a built-in timer that you can set for 4 hours tops. At the end of the time you select, the unit will turn off to save energy. It’s fairly easy to use due to the user-friendly backlit LCD screen where you can check out humidity and temperature levels in the room. There’s one downside that we must mention, however – the warranty is only 3 months long.

  • Filter-free design for cheap upkeep – emits anions to purify the air instead
  • The large-capacity tank keeps it running in humidifier mode for up to 28 hours without interruption
  • Large coverage – count on it for spaces of up to 538 square feet
  • The night light function features changing colors, soothing you to sleep

  • Makes a loud beep noise when the water tank is empty
  • Tends to leak a bit when you take it off the base


Compact, modernly designed, and easy to maintain since it doesn’t use a filter to clear the air of impurities, the bblüv is an option people are quite fond of. Needless to say, the cheap asking price is another plus.

9. Luminous AH2034

Check Price at Amazon

  • Room coverage: 100 sq. ft.
  • Filter media: H13-grade HEPA filter, activated carbon filter, pre-filter
  • Purification efficiency: 99.9%
  • Water tank capacity: 23.7 ounces
  • Humidity output: N/A
  • Speed settings: 3
  • Noise level: Low
  • Dimensions: 5” x 5” x 8.2”
  • Weight: 2.2 lbs.
  • Warranty: 3 months

Luckily for you, if your budget is limited, the Luminous AH2034 is an option that you can surely afford, a product that doesn’t sacrifice quality in the slightest despite the cheap price. The only downside that doesn’t make it very appealing in all situations is that its peak area coverage is only 100 square feet. So, which it might be more than perfect for small rooms (bedroom, nursery, and so on), you can’t rely on it for purifying the air and raising moisture levels in the larger spaces of your home.

It is fitted with a BLDC motor that helps it output quite a hefty airflow, and there are 3 speeds to pick from. On the lower of these 3 speeds, it makes so little noise that you can sleep in its proximity, and it doesn’t consume a lot of energy either. When it comes to its air cleaning abilities, know that it relies on 3 efficient filtration means to rid the air of impurities, namely:

  • Pre-filter: Removes the larger-size particles to make it easier for the following filter media to do their job.
  • Activated carbon filter: It’s responsible for ridding the air of smoke and odor-causing particles so that the room you place the unit in smells fresher than ever.
  • H13 HEPA filter: Traps the remainder of airborne particles with a removal efficiency rate of 99.9%, and it even removes impurities down to 0.3 microns.

When it comes to its humidification capabilities, it handles adding moisture into the air sufficiently well to replace the need for a standalone humidifier in an appropriately sized space. Since the tank is a top-fill model, you won’t have much trouble refilling it – just pour water into the opening at the top of the unit. Occasionally, you must not forget to detach the tank and give it a quick rinse so that any residues are removed.

You only have to replace the humidifier and air purifier filters every 6 months. What you must keep in mind, however, is that the humidifier filter will require periodic cleaning – wash it every 2 weeks and reuse it until the aforementioned 6 months pass and the time to change it comes. Woefully, the warranty period isn’t as extensive as it is with other products – this model is backed against defects only for the first 3 months.

  • During the 3-stage air cleaning process, it removes the likes of odors, dust, allergens, smoke, and more
  • Top-fill design makes it easy to fill the tank when it runs out of water
  • The humidifier filter is washable and reusable for up to 6 months, while the HEPA air purifier filter needs direct replacement every 6 months
  • Budget-friendly deal – comes at a very affordable price

  • Unclear assembly instructions
  • Recommended only for small areas – 100 sq. ft. tops


Perfect for small spaces since it is rated to cover only 100 square feet, this Luminous 2-in-1 product is a reliable option to consider, one that won’t cost you a fortune to acquire either. The H13 HEPA filter that it mainly counts on for air purification tackles pollutants of all sizes and seeing how it has a pretty decent humidity increasing capability too, it will make an immediate difference for the better.

Is It Worth Buying?

Useful for individuals who experience the ill effects of hypersensitivities, asthma, or other respiratory issues since it can expel the triggers that trigger or compound these conditions. Interestingly, moisture-increasing devices can give help to individuals who experience the ill effects of colds, influenza, sinus blockage, and dry hair and skin.

Fundamentally, a combo device would have the capacity to address every one of these issues viably, so in case you are confronting any of the aforementioned problems, at that point, it is the appropriate response. But there are upsides and downsides to any product, and the combo device makes no exception to this rule. To help you figure out where you stand when it comes to making the acquisition, here are the pros and cons that you need to be aware of before drawing a definitive conclusion.

  • Convenient: The convenience aspect is undeniable as less space will be occupied indoors to tend to the fixing of 2 different air quality issues, you will have less maintenance work on your hands as you will tend to monitor and care for a single device, and maintenance costs will be reduced as a result of this 2-in-1 design as well.
  • More problems solved: Obviously, the dual function provided benefits you greatly as more air quality issues are being tended to simultaneously. This means that you enjoy living in a healthy space when you are at home, one where you will feel safe and where you won’t be predisposed to respiratory issues anymore.
  • Budget-smart: Although most models tend to come at quite spicy prices, they still make for smarter acquisitions when compared to the separate purchase of moisture-increasing devices and air cleaning units. Thus, in the end, you save money by making this deal.
  • High maintenance: It might do the job of two separate devices at once, which is an incontestable perk, but this implies that it is twice as pretentious when it comes to maintenance work as well as the air purification media and the moisture dispensing element need attendance.
  • Higher asking price: When compared to standalone air cleaners, combo devices are more expensive. However, this isn’t a surprising aspect as it provides two important functions that contribute to the boost of your health. Additionally, it is not a general rule as some systems are quite reasonably priced and accessible to a wide range of customers.
  • Not always as effective: Because it serves two different functions, it comes as no surprise that it might disappoint when it comes to one of its fulfilled functions. This isn’t necessarily true with all models, however, new generation higher-priced devices delivering a surprising performance when it comes to both functions.

Frequently Asked Questions

Performance Q&A

Is it as performing as separately purchased purifiers and humidifiers are?
The answer to this question varies depending on the specific product at hand as some models are equally if not higher-performing than their individual counterparts, while other models are indeed less performing, not being able to increase moisture and remove contaminants with the same effectiveness provided by separate devices.

Will it help eliminate bad odors?
Generally, issues related to bad odors indoors are fixed with the help of an activated carbon filter that is specifically designed to absorb the particles which cause the appearance of the odors to start with. Thus, if you want to target bad odors, we recommend you opt for a model that features this filtration media.

What are the health issues it helps prevent?
Seeing how it performs not one, but two separate functions that both collaborate to create safer and cleaner air indoors, there is a wide range of health issues it prevents. Among the most important issues it keeps at bay are included congested sinuses, dry skin, dry hair, skin irritations, colds, allergies, asthma attacks, and other types of respiratory system problems.

Maintenance Q&A

How often is filter media replacement required?
This depends on the specific model at hand, some systems requiring it more often than others. Some systems use different methods to rid the air of impurities, not relying on filters, which don’t require this maintenance procedure. If your pick does feature filters, however, you should check the user manual or spec sheet to see when and under what circumstances you will need to make the change.

For models with a water tank, what type of maintenance is needed?
It is preferable that you take out the water tank and thoroughly clean it using a vinegar and water mixture once per week. Otherwise, you risk for bacteria to form in it and for the device to start releasing impure moisture into the air, thus putting your health in danger as you inhale these harmful contents.

What happens if I don’t refill the water tank on time?
If you don’t refill the water tank on time and the system doesn’t feature an automatic shut-off set in place for this specific occasion, you might end up overheating the device and rendering it useless. On the bright side, all quality systems come with this safety feature in place to prevent this occurrence.

Other Questions

Does the risk of over humidifying the air exist?
Yes, this risk does exist, and you must avoid over humidifying the air at all costs as it leads to the appearance of mold and mildew, their spores presenting a great threat to your health when inhaled. To make sure this won’t be an issue, only use the humidifying function until indoor moisture levels reach 60%. Never let moisture levels exceed this limit as a perfect growing ground for the aforementioned pollutants is created.

Is it more energy-efficient than separate devices are?
Because instead of running two separate devices you will operate a single unit, it is safe to say that, regardless of how much power it draws, it is still more efficient in terms of energy consumption than a separate moisture increase device and air cleaning device would be.

What are the features/specs that matter the most?
As it is supposed to fulfill two different functions, the specs and features you must be on the look for involve both functions. Make sure that the system can remove as many airborne pollutants as possible, preferably over 99% of them, and that moisture output per day is as high as possible for dryness levels to be fixed fast.


Since all of our picks fulfill two functions, not one, all of them increasing moisture and effectively clearing the air of pollutants, it was rather difficult to rank them as we view them all almost equally qualitative. What you must take away from what you have read is the importance of acquiring and using a system in your home to create a pleasant and healthy habitat in the most convenient, space-efficient, and budget-smart manner possible.

It is Energy Star certified, so its operational prowess in terms of energy consumption is hard to surpass. To increase room moisture, it uses a humidifying filter that requires replacement every couple of years. When it comes to air filtration and removal of particles, it uses a HEPA filter that can even tackle dust, as well as an activated carbon filter that gets rid of nasty odors. Moreover, it doesn’t make much noise when it runs, so you can place it in the bedroom or office if you like without worrying it might be a distraction.

Best Air Purifier and Humidifier Combo for Baby: Venta LW15 Airwasher

A filter-free model that outputs upward to 0.64 pints per hour and eliminates 99% of airborne particles, the Venta Airwasher seems specially designed for use in the nursery as it not only enhances air quality to create a safe environment for the baby but because it produces only 22 decibels when set at the low operational setting.

Best Air Purifier and Humidifier Combo for Bedroom: Boneco H300

When you select a device for the bedroom, one of the first aspects to look into, aside from the obvious performance related to humidity output and air purification, is how loud it gets when it runs as you need a silent model to run it when you sleep. Thus, the H300 was an obvious recommendation as it produces a mere 28 decibels on the lowest speed setting. Moreover, it even features a predefined profile specifically for bedroom use during nighttime, namely the Sleep mode. When used with this function active, it adjusts settings to support a restful night’s sleep.

Best Air Purifier and Humidifier Combo for the Money: Envion FS200
