How to choose
Match coverage to your room size
Coverage in square feet is the figure the maker gives for the space a dehumidifier serves. The maker lists 5,500 sq ft for the yaufey, 2,500 sq ft for the Kesnos and 2,000 sq ft for the Waykar. Compare that figure with your room's floor area, and remember that moisture removal is measured at 95°F and 90% RH for all three picks.
Moisture removal and humidity range
Moisture removal says how much moisture a unit removes in a day under test conditions. The yaufey, Waykar, and Kesnos are tested at 95°F and 90% RH. An adjustable humidity range, 30% to 80% on the yaufey and the Waykar, lets you set a target level instead of running flat out.
Drainage, tanks and upkeep
A tank needs emptying when full, while a drain hose gives continuous drainage to a floor drain. The yaufey has a 1.06-gallon tank and a 3.28 ft hose, the Kesnos a 0.39-gallon tank and a 3.3 ft hose, and the Waykar a 0.62-gallon tank and a 3.3 ft hose. All three picks have a washable filter, so rinse it on the maker's schedule.
