Mainstays 45 pint dehumidifier
Damp and dingy basements, rooms and offices are a thing of the past with this elegant 45 pint (21.3 litre) capacity Mainstays dehumidifier. This unit is just what the doctor ordered if you’re trying to eliminate excess moisture from areas up to 2,500 square feet in size. You’ll be able to cut down on electricity bills with this clever Energy Star-compliant model and you’ll certainly become a friend of the environment with its R410a refrigerant. The appliance features adjustable humidity settings and a pair of fan speeds which can easily be controlled electronically. The quiet operation will allow you to sleep well and concentrate on other things while it’s running. Ice build-up on the coils is a thing of the past as the auto de-icing system eliminates the problem. The dehumidifier can keep running until the temperature reaches 5ºC (41F) with sharp low-temperature feature. It also comes with a direct-drainage system and easy-roll castors for moving it about. Cleaning this model is also a breeze as the filter can easily be removed.

Rated 3 out of 5 by from Decent humidifier This humidifier works wells for a reasonable price. I have it running in my average sized basement to eliminate the moisture form a large fish tank. This humidifier took the humidity down right away from 60% to 47% it's not quite big enough to drop to my ideal resting point of 45% The continuous drain function works well with no leaks. Because it's only a 45 pint I do have to keep it running practically 24/7 to keep the humidity down. A larger one would be nice to really get a wet area to a resting humidity of choice.

Rated 5 out of 5 by from Dehumidifier I'm very pleased with this product, it does what it's supposed to do. We had a big humidity problem in our house and we purchased two dehumidifiers placed in different area of the house and our problem is solved. Fabulous product.

Rated 4 out of 5 by from works great glad I bought it. I bought this a month ago. It takes the excess water from the air just fine. Wish the water reservoir was bigger as it needs to be emptied frequently. It is a great size though not excessively loud so with the price being good definitely a buy.

Rated 5 out of 5 by from Great value and performance I purchased this dehumidifier for our basement. The price is great considering it's a Danby product and holds 50pints of water. I've used it for 3 weeks and it's been performing without any issues. It's relatively quiet and lighter than I expected. I had a Bionaire 42pint unit that weighed much more and only lasted 2 years.
