I tried different ones before and this is the one I kept. it's easy to move to places and it's not too bulky. I live in a one bedroom apartment and I feel that helps to reduce humidity in the other parts of the apartment (I place it in the bedroom). Other things I really like is A hose for draining water.I don't have to worry about when the water will fill up, I just connect the hose to the sewer line, and the hose is long, easy to use. then I no need time monitoring.

3.I live in Florida and it gets very humid sometimes and even if the thermostat set for lover temperature you feel very uncomfortable because of humidity. This one is perfect for my living room that is an open space with a kitchen and dining room (about 1000 sq ft.) It reduced humidity super quickly and keep it on the level that I set it for. Works pretty quiet but the only thing Overall definitely recommend and it's much cheaper than well-known brands. My energy bill hasn't changed as well, so I think it's pretty energy efficient.

The dehumidifier has been in operation for 2 months and we are very satisfied with it! It is not very loud and the noise level is perfectly acceptable. It is equipped with an air filter, which is very suitable for our basement. Since we have been using dehumidifiers, the humidity in the basement is always within an acceptable range, and it feels comfortable to enter the basement again. Generally speaking, we would definitely recommend this dehumidifier!

It works and keeps the humidity level of our crawling space down. We also bought a remote control to realize the remote control of the dehumidifier. So far, it is a great product and we have been using it for about 4 months.

I bought it to prevent my power frame and heavy objects from rusting in the garage. We have been using it for a few weeks and this sturdy unit has been running non-stop, sucking moisture from the air like a champion. Our humidity and related problems are gone! No regrets.

Amazing dehumidifier! It really works!
By 'Kaylee Wynn', Reviewed on January 25, 2021
I am very satisfied with this dehumidifier. It keeps the entire basement dry and comfortable and really helps to eliminate the smell of the basement. When the required humidity is reached, it will shut down. The filter is easy to clean. We use the hose function to drain the water directly into the drain without worrying about emptying the bucket. Although our basement is more than 2,000 square feet, the dehumidifier seems to be able to handle a slightly larger area with acceptable humidity.
Excellent dehumidifier
By 'Lance Leonard', Reviewed on January 18, 2021
Easy to use. Compared with our old dehumidifier, the volume is smaller. I use a hose to drain-it works great! It always keeps our large basement between 40-45% humidity, which is very comfortable and will not smell musty when running this dehumidifier. I can actually enter the basement without pain. This dehumidifier is amazing. Works very efficiently!
