Why it matters
The Waykar DP-B Dehumidifier is a crawl space and basement dehumidifier, rated for 7500 square feet.
Aim for 40 to 60 percent relative humidity indoors: drier air irritates airways and skin, wetter air feeds dust mites and mold.
The listing names a built-in condensate pump, a drain-hose connection and a commercial-grade build.
A condensate pump pushes water up and out through a hose, to a sink, a window or a drain above floor level, so the unit never stops for a full bucket.
A drain hose lets it run without emptying a bucket, as long as the hose runs downhill to a floor drain.
At its stated 520 watts, running non-stop uses about 12.5 kWh a day; in practice the compressor cycles off once the room reaches the set humidity.
Its rated area of 7,500 square feet is one of the largest ratings we cover: 97 of the 99 dehumidifiers with a stated figure come in lower, and the range runs from 110 square feet to 7,500 square feet.
Price-wise it sat in the middle third of the 25 basement / crawlspace models we cover when we checked; the button shows today's price.
It qualifies for our lists Best Dehumidifiers for Basements, Best Crawl Space Dehumidifiers, where it is ranked against every model that meets the same rule.
