Good value but noisier than an older unit

Certainly takes the water out of the air. Bought for an old farmhouse, easy to use and sucks the water out very fast and efficiently. Noisier than another dehumidifier I have and vibrates on soft surfaces. But would recommend.

Excellent product

An excellent product. Does exactly what you would want it to. Cannot believe how much water it collects from a variety of rooms in our home. Also, excellent service from AO.com.


I already have an older model Dimplex which I love so bought this for another room still does as good a job as the old one but the only complaint I have is it’s quite a bit noisier

Excellent product.

Bought this to replace a old unit that failed. Big improvement on our old unit.


Although a little bit more noisey than my other dehumidifier I can safely say this is much better and cheaper than my other 1

Excellent dehum...

Excellent dehumidifier. Even dries my laundry in double time.
