I live in a very wet area and as a result mold and mildew easy accumulates in the home. A Dehumidifier is a necessity. Since using this one in our basement, the mold and mildew hasn't been a problem. It comes with a high price tag that I wish could be lowered a bit, but it's worth the money you pay. I don't recommend using this is a smaller room. We used this for a few days in a 12x12 room and it made the room hot and the air stuffy. If you have to have a dehumidifier for a small room, get a smaller one. This unit sounds like a fan, which I quite enjoy the noise when sitting quietly to myself, but I don't recommend you try having a conversation, listening to music, or watching TV with the unit unless you are used to the sound of a fan running. Effectiveness This is very effective in our basement. We had it in our smaller bedroom but the environment felt very odd after we used it in there for a few days. Safety Never had any worries regarding safety with this. Ease of Cleaning Very easy to empty. Durability We've only had ours for a few months, but other people I know have had to get a new one every few years. Design Very clean and sleek looking design. It's easy to empty having two options to do so. I had to contact Frigidaire company to get the drainage kit. I did it via their website.
