How to choose
Coverage is the maker's figure
Coverage tells how large an area the maker rates a cooler for. The AIRCARE is rated for up to 2,700 sq ft, the Uthfy up to 1,200 sq ft, the SereneLife up to 700 sq ft, and the Ashihoti up to 150 sq ft by their makers. Compare that figure with the area you plan to cool, and note that airflow in CFM is a different figure from square feet.
Airflow, tanks and speeds
Airflow in CFM sets how much air the cooler moves, tank size sets how long it runs before refilling, and speeds set intensity. The Uthfy moves 4,800 CFM with a 10.6-gallon tank and 3 speeds, the SereneLife moves 1,800 CFM with a 4-liter tank, and the Ashihoti moves 100 CFM with a 3-gallon tank and 6 speeds. The AIRCARE pairs a 6-gallon tank with digital controls and an auto humidistat.
Controls, timers and mobility
Controls set how you change speed and mode: the Ashihoti and SereneLife use remote and touch control, while the AIRCARE uses digital touch controls and the Uthfy uses a mechanical panel. For mobility, the Uthfy rolls on four casters with brakes on 2, and the Ashihoti rolls on 360° casters.
