How to choose
Read coverage as the maker's figure
The useful number for a large room is the coverage each maker gives: 7,500 sq ft for the Kesnos, 6,000 sq ft for the AEOCKY, and 5,000 sq ft for the Waykar, the KNKA and the Ludatido. These are the makers' own ratings, so compare them against your room's floor area rather than treating them as a promise for every room.
Tank size and drainage
A larger tank means fewer trips to empty it: the Kesnos holds 8 L, the Ludatido holds 6.5 L, the AEOCKY and the KNKA hold 5.49 L each, and the Waykar holds 4.3 L. Each pick here also offers continuous drainage by hose, so a floor drain or sump nearby removes the emptying chore altogether.
Noise, timers and modes
Stated noise figures here include 42 dB for the Waykar and the Ludatido, 44 dB for the AEOCKY and 40 to 45 dB for the KNKA. Every pick here has a timer, and modes like Sleep, Dry and Auto let you match the unit to night use or faster drying.
