Moreover, the costs can be decreased if you utilize the 24-hour timer that makes it shut off after a full day of running or the specific amount of hours that you select. Thus, you can turn it on again only when air moistness seems to be increasing and save good money.

A 6-foot power cord lets you position it far from the wall for better ventilation and a higher air intake. Plus, though it is fairly heavy, with a weight of 30 pounds, it can be effortlessly transported due to the heavy-duty handle that can lift a load of up to 150 pounds. Besides the excellent-quality design, it is backed by a 5-year guarantee provided by one of the most reputable manufactures.

Q: Can I use a regular-size garden hose for the drain outlet?
A: Yes, you can couple an ordinary garden hose to the outlet. However, bear in mind that it depends on gravity for the discharge process, so you must place the hose upright facing downwards beneath the height of the unit.
What we like:
  • Produces a small amount of noise when it runs
  • Fitted with a handle for effortless transportation
  • Hassle-free upkeep guaranteed by the easy-access filter and splash protector bucket
  • 5-year assurance has you covered if defects arise
What we dislike:
Verdict

It is a reliable unit that will last you for many years to come. It integrates a powerful fan that can rapidly remove large quantities of moisture from the air, thus averting the risk of mold growth. Apart from that, upkeep is a breeze since the container has a splash guard, which makes emptying it a cinch and keeps the whole operation spill-free.

If you pick the latter, don’t forget to let it air dry completely. When you are finished cleaning it, put the filter back in its initial position, reinsert the back panel, and you can go ahead and run the moisture extractor if you want to.

Frequently Asked Questions



Do dehumidifiers work in bathrooms?
Yes, since the entire job of the moisture extractor relies on wicking excess dampness from the air, and the lavatory is one of the rooms where proper moistness levels are difficult to uphold without the support of a specialty system, opening windows, or other tricks. As high moisture leads to issues with mold and bacteria development, and humidity cannot stay within healthy limits in the lavatory without extra assistance, using a dehumidifier here is actually an issue of safety.

Where should it be placed in a bathroom?
There is no specific location in a bathroom where it’s better to place it. As long as it is close enough to an outlet that you plug it in for power and it’s physically in the restroom, there won’t be any issues to concern yourself with as it will wick away the same volume of moistness regardless of where exactly you place it.

How do I dehumidify my bathroom naturally?
If you don’t want to utilize the moisture extractor system, which is the best solution, by far, you can always turn to other creative methods to remove excess moisture in this room. Some of these include opening the door and window after you shower, turning on the ventilation system, turning on a fan, taking shorter showers to reduce the amount of moisture that forms, or even using a space heater that dries the air while warming the room.

How do I stop my bathroom walls from sweating?
To impede this occurrence, you should regulate the temperature in the lavatory, namely to set it a bit higher. Turn the thermostat up a few degrees, and the cold surfaces in this room will become warmer, which in turn leads to reduced condensation. Another solution to raise the temperature here a bit is to install an electrically heated towel rail that comes in handy as you can even dry towels with it.

What size unit should I use for the bathroom?
Start with the basic calculations for sizing an air purifier. Measure the length and width of your bathroom, and multiply the values to learn the square footage. Contingent on room size, these are the estimated basic PPD values that you should look into:

  • 25 PPD – for damp rooms that measure from 0 to 300 sq. ft.
  • 30 PPD – for damp rooms that measure from 300 to 500 sq. ft.
  • 40 PPD – for damp rooms that measure from 500 to 800 sq. ft.

We stop here with the moisture extraction estimation as it is highly unlikely that you will necessitate a restroom dehumidifier that can cover an area larger than 800 sq. ft. to the standards we have enumerated here since we are talking about a unit that should handle a highly damp space, you should add another 5-10 PPD as the aforementioned stats apply to normal rooms.


Do you need a dehumidifier in every room?
There are whole house dehumidifiers that can handle large areas, but it’s advisable to target specific rooms by using separate units. You don’t necessarily have to buy several, considering that most come with wheels and handles for increased portability.
Can I use a dehumidifier instead of a bathroom fan?
If you don’t have an exhaust fan installed or the one you have can’t handle all the moisture, a dehumidifier is the best option to resort to. Running it after a long shower or even an entire day to get rid of mold and mildew will show optimal results within the first use.

How do you dehumidify a bathroom without a fan?
Keep the doors and windows open while you shower, to let the air circulate and dry the vapors.
Wipe the condense off the tiles in the walls
Don’t leave wet towels drying in the bathroom
Plug in a dehumidifier
