Match coverage to your room
Coverage is the number that decides a large room pick. The Levoit is rated for up to 505 sq ft by the maker, the KZF and the Crane for up to 500 sq ft, and the Pure Enrichment for up to 475 sq ft. Measure your room first and pick a maker rating at or above your room size.
Tank size sets refill frequency
A larger tank runs longer between refills. The KZF holds 9 liters and runs up to 72 hours per fill, the Levoit holds 6 liters and runs up to 60 hours, and the Pure Enrichment holds 3 liters and runs up to 30 hours. The Crane holds 1.2 gallons. If you dislike frequent refills, favor the larger tank and longer run time.
Top fill and upkeep
Every pick here fills from the top, so you pour water in from above instead of lifting and turning the tank. The Levoit and the Pure Enrichment include a cleaning brush in the box, and the KZF tank detaches for filling. Rinse and refill on a regular schedule to keep the mist steady, and every pick here has auto shut-off.
