We bought this as a recommendation as our AC was running constantly trying to keep things cool the first week it ran and ran and ran I didn't think that it was supposed to do that we emptied 20 gallons of water and then it's slowed down and the air stopped running so much and now it's comfortable and it keeps. The house much cooler I even put my thermostat up because it became colder than I expected. I would recommend this dehumidifier it's top shelf thanks
