How to choose

Modes and air movement
Modes set the wind pattern. All three coolers run 3 modes and 3 speeds. The Deco-natural and the SereneLife run Normal, Natural and Sleep, while the Ashihoti runs cool, natural wind and sleep. The Deco-natural swings 70 degrees for even air circulation, and the SereneLife moves air across 60 degrees. Check the movement style against the room you cool.
Tanks, timers and remotes
Tank size sets how long cooling runs before a refill, and timers set when it stops. The Deco-natural holds a 9L tank and the SereneLife holds a 5L tank, while the Ashihoti runs up to 20 hours on a fill. Check tank, timer and remote before choosing.
