1. Aprilaire 700

Check Price at Amazon

This is a whole-home humidifier that mounts directly to the supply or return duct of your heating and cooling system. The moisture output is impressive, as it must cover the entire home, ensuring 0.75 gallons of mist every hour, summing up to 18 gallons of water each day. This is more than any other model we have reviewed so far. The built-in fan is responsible for spreading the moisture on over 4,200 sq. ft. and can operate around the clock, as it connects to a water line instead of relying on an internal reservoir.

Automatic Control

The assembly includes the actual housing with a water panel and a humidistat that must be connected to the device, at the bottom. There, you will also find the water connection and an outlet for the drain.

The humidistat, which is installed on the return air duct, analyzes the air in your home. If it senses humidity below the set level, it will tell the machine to start delivering moisture. As this happens, water falls into the distribution tray and down over the water panel. Dry, hot air is then pushed from the furnace into the humidifier’s water panel, creating a natural evaporation process. The water vapors created by the furnace are then pushed back into the air duct via the fan and spread widely all over the house. This way, the moistness balance is restored to the level you select on the humidistat.

As you can see, you never have to monitor the settings or wait until the indoor air becomes too uncomfortable. What you must be aware of is that the mounting must be done by a professional, as it must be mounted on the furnace of your home by cutting a hole through it. The process will also require wiring and hooking up to a water supply, as well as adding a drain that will evacuate the remaining water.

Why Humidified Air Is a Necessity

Although it’s easy to overlook it, the level of humidity in the air is significant. In the ideal case, it would be recommended to preserve air moisture levels within 40 to 60 percent. Pay attention to this specific stat at all times as low humidity is actually quite damaging to your health. This isn’t to say that high humidity doesn’t come with its own set of repercussions, but this is a topic covered in the section for dehumidifiers.

• Viruses – in low humidity, viruses and bacteria thrive and live much longer. Therefore, you will be at risk of contracting infections. Plus, when the flu season arrives, those with humidified air will be much more protected than those who do not benefit from the functioning of a moisture-augmenting system.
• Nasal congestion – when the air is dry, it gets quite difficult to inhale properly. If you come down with the cold or flu, it’s even worse as nasal congestion follows and breathing is made all the more difficult.
• Skin – low moistness levels and cold temperatures will cause havoc to your skin. If you’re suffering from dry, prickly, and irritated skin, it’s a must that you consider this product. It is especially imperative for those who suffer from eczema.
• Eyes – when you’re suffering from dry and irritated eyes, you know how difficult life can be. This system will ensure that the air that comes in contact with your eyes is moist enough not to affect them.

Humidifier Sizing

Once you’ve decided which system fits your preferences, you need to decide whether it fits your room’s requirements. Though the main aspect that you should look for is the applicable area, you must also consider other factors that can determine how efficient the product is. You can get the highest possible efficiency from the system by looking at the following factors:

Coverage

All of the models mentioned in this review have large square footage. Ranging from 200 to 4,000 sq. ft., you can surely find the one that will fit your large living space. Moreover, you will have to look at the extent of moisture it will typically add to the area within 24 hours. Remember, too much moisture can be detrimental.

Nonetheless, it’s often found that manufacturers are not truthful when it comes to the mist output. Hence, if your room measures up to 200 sq. ft., you should go for a unit that will cover around 360 sq. ft. This will ensure that the mist is diffused evenly throughout the room.

Room Insulation

These units circulate the air in a room several times per hour. Thus, the amount of air that flows into the room will determine what size unit you need. If your home is overall tight or has insulation into the walls, you will need to aim for a smaller size model than the square feet of your living space.

The opposite is for drafty homes. If you have a lot of windows and doors, the airflow will be much larger, hence, the system has to work harder. If you fall into this category, make sure to acquire a model with proper coverage.

Room Volume

You may have seen numerous charts with the same numbers if you’ve ever searched this subject before. The problem with these charts is that they are calculated according to standard ceiling heights. Recently, ceilings have been made with a height of up to 9’. Before, the standard ceiling size was 8’.

It’s obvious that every house is different, thus, you need to look at your ceiling height. If your house has a higher than usual ceiling, you will need a system with higher coverage than your home’s sq. ft. as this will ensure even coverage.
