Works Well, Then Breaks Down,
Verified Purchase(What is this?)
This review is from: DD122FW-MK4 Dehumidifier
I've been using dehumidifiers in my house for five years because of condensation problems. There are basically two types: desiccant dehumidifiers and compressor dehumidifiers. The compressor type uses less energy but is quite weak, so it's only really suitable for use in rooms where you can leave it running 24/7, such as an attic or a cellar. The noise it makes means it would be too annoying to run constantly in a room that you spend a lot of time in. If, like me, you have to solve a condensation problem in a living room, you'll need a desiccant dehumidifier. They're more expensive to run, and (in my experience) noisier, but they're far more powerful, so you can run them overnight.
This DD122FW-MK4 is a desiccant type that works brilliantly at removing moisture from the air overnight. When I go to bed the relative humidity in my living room is about 70%. In the morning, this machine has it down to the high 40s. As soon as I switch it off, the humidity starts climbing, but at least the room is comfortable for the first half of the day and there is no longer condensation on the windows.
The downside, and it's a biggie, is that I have used three of these machines and they've never lasted longer than 18 months. The most recent one I bought lasted 5 months. £150 is a lot of money for a machine that's probably not going to last you a year. However, having recently experimented with a compressor type, I see no option but to go back to something like this. Perhaps the answer is to buy a more expensive model of this type.
