How to choose
Cool mist versus warm mist
Cool mist adds moisture without heat, while warm mist heats the water before it leaves the unit. All three picks give both: the Levoit pairs warm and cool mist with a double duct design, the Homedics gives warm or cool visible mist, and the Honeywell gives cool mist and warm mist with temperature control. Warm mist runs between 40°C and 60°C on the Levoit. Pick the mist type that matches the season and your room.
Tank size and runtime
Tank size and mist setting set how long a fill lasts. The Levoit runs 60 hours on 6 liters, the Homedics runs up to 90 hours on 2 gallons, and the Honeywell runs up to 36 hours on 1.5 gallons. Runtime figures depend on the mist setting and room conditions, as noted for the Homedics. A bigger tank means fewer refills, but check the runtime figure too, since settings change how fast water is used.
Controls and upkeep
The Homedics and the Honeywell shut off on their own when out of water. For upkeep, the Levoit box includes a cleaning brush and a water filter sponge, the Homedics includes 3 demineralization cartridges and a clean reminder, and the Honeywell needs no filter changes.
