It's still working like new

I've been using the 50 pt model in our below grade basement since August of 2024. I don't need to run it from about mid November through the end of February. It was the first dehumidifier I decided not to review right away. I purchased too many over the years that I left 5 star reviews for shortly after receiving them, then they'd stop dehumidifying. It's now June 23, 2025, and the Keystone is still working perfectly, even better than the more well known brands. It's not too loud either. Fingers crossed I haven't jinxed myself by leaving this review.

It just works well

It just works well and as expected. We used this to replace a Aeocky brand that is rated one of the best online but didnt last 5 months. Keystone has always been a reliable brand for us. We use it in a large open basement keeps humidity at 45% as we have it set. The noise level is ok for a basement setting. We had 2 smaller units in the past for humidity in our living room and bedroom. They both went in the basement till we got our new keystone and then we donated them because they got dirty. But they still kept working.

Efficient. Lowers humidity into the 30s quickly.

Once you get the little knack of sliding the water collection bin in and out easily, this is an outstanding workhorse. It's in our 20'x 15' living room (in a 1000 sq. ft. city apartment) located near a large major river that we get plenty of humidity from. It's unbearable here without a dehumidifier in the summer. I've had plenty of dehumidifiers in the past, and this one's the best, at a reasonable price. Love ya, Walmart.
