How to choose
Read coverage as the maker's figure
Coverage is the maker's own figure for the space a unit serves, so compare it with your basement floor area. The AIRPLUS, Midea and Lienuis are each rated for up to 4,500 sq ft by the maker, while the Wellsle is rated for up to 3,500 sq ft by the maker. Tank size also differs, from a 3.8 L tank on the AIRPLUS to a 6.06 L tank on the Midea, so compare coverage and tank size together.
Tank size, pump and drainage
Tank size sets how much water the unit holds before it stops or drains, and a pump or hose sets how it empties. A pump drains up or out of a window, while a hose needs a floor drain or sink.
Noise, timers and controls
Noise in decibels tells how loud a unit runs, and a timer sets when it starts or stops. The Lienuis runs at approximately 40 dB, the Wellsle stays at or under 41 dB, and the Midea runs at 49 dBA in low mode. The Wellsle and Lienuis have 24-hour timers. The AIRPLUS has a humidity control with a continuous CO mode, while the Midea has continuous draining. The Midea also adds Wi-Fi control through the SmartHome app.
