Humidifiers for the Bedroom

Dry winter air and heating leave a bedroom feeling parched by morning; a humidifier is the usual fix, and three things decide which one. Tank size versus runtime: a night is 7–9 hours, small sub-0.5 L USB units suit a nightstand and run for a few hours, while 1–2.5 L tanks cover a full night and 4–6 L units a whole bedroom. Noise: light sleepers should look for a listed figure below about 36 dB. Cleaning: a tank you can rinse in seconds is one you will actually clean weekly.

Use distilled water in ultrasonic units to avoid white dust, and look for a timer or water-shortage auto-off if it will run while you sleep. Night-light models put one device on the nightstand. We make no health claims for humidifiers. For room-size maths, read the bedroom humidifier guide.
