How to choose

Read coverage as the maker's figure

Coverage is the first number to compare, and each maker states it differently. The Levoit is rated for up to 753 sq ft by the maker, the AIRCARE for up to 2,700 sq ft and the Lacidoll for up to 3,000 sq ft. These are the makers' own ratings, so compare them against the floor area you want to cover rather than treating them as measured room results. Runtime per fill is a separate number: the Levoit runs 50 hours on 6 liters, the Lacidoll 40 hours on 26 liters, and the AIRCARE 6 hours on 6 gallons.

Evaporative versus ultrasonic output

An evaporative humidifier blows air through a wet wick so water leaves as vapor, while an ultrasonic humidifier vibrates water into a fine mist. The AIRCARE is the evaporative pick here, using a 1043 Super Wick, and the Levoit and the Lacidoll are ultrasonic. Ultrasonic models in this list offer cool mist, and the Levoit adds warm mist as well. Wick models need a wick on hand, while the Lacidoll notes it needs no replacement filters.

Controls, timers and upkeep

The Levoit adds app and voice control with schedules. The AIRCARE uses digital controls with an auto humidistat. The Lacidoll uses a remote or touch buttons with a 12-hour timer. Top-fill tanks on the Levoit and the Lacidoll make refills simpler, and a water level window on the Lacidoll shows the level at a glance.
