How to choose
Match the maker coverage rating
Start with the coverage figure each maker gives, and compare it with the floor area you plan to dry. The Aeroid is rated for up to 1,200 sq ft by the maker, the ALORAIR for up to 1,300 sq ft, and the Waykar for up to 6,500 sq ft. Check the coverage rating before choosing.
Compare moisture removal figures
Moisture removal states how much moisture a unit removes in a day, and each pick states its figure at saturation or at maximum. Compare figures stated under the same conditions, since saturation and AHAM figures describe different test conditions. Use the coverage figure alongside the moisture figure when you compare picks.
Plan drainage and placement
A built-in pump lets a unit drain upward to a higher drain point, while a gravity hose needs a lower drain point. The Aeroid pump supports vertical drainage up to 16.4 ft, and the Waykar pump also drains up to 16.4 ft vertically. Check hose lengths, the 6.5 ft Aeroid gravity hose and the 6.6 ft Waykar gravity hose, and place the unit where the hose reaches the drain.
