What to look for in a bedroom dehumidifier
- Noise. Thermoelectric units are the quietest; compressor units are louder but remove far more water. If noise is your top concern, see our list of the quietest dehumidifiers.
- Sleep mode and dimmable lights. A bright blue LED in a dark bedroom is surprisingly annoying.
- Auto shut-off. Every model here stops when the tank is full, so nothing overflows overnight.
- Built-in humidistat. Lets it stop at 45–50% instead of running all night.
- Filter. A washable filter is standard; a HEPA filter adds some air cleaning for allergy sufferers.
How much it costs to run overnight
A compact thermoelectric unit draws about 25–50 W: running 8 hours a night at around 17 cents per kWh, that is roughly $1–2 a month. A 20–22 pint compressor unit draws about 250–300 W, roughly $10–12 a month for the same use. The full math is in our guide to how much electricity a dehumidifier uses.
Tips to keep a bedroom dry for good
- Air out the room every morning: one person breathing all night adds moisture to the air.
- Pull the bed and dresser a couple of inches away from exterior walls.
- Do not block heating vents or radiators with furniture.
- Run the bathroom fan during showers and keep the bathroom door shut.
- Check the humidity with a cheap hygrometer to know whether the fixes are working.

Frequently asked questions
Is it safe to sleep with a dehumidifier on?
Yes. Modern units shut off automatically when the tank is full and cycle with the humidistat. Keep it on a hard, level floor, a foot or more from the bed and curtains, plugged straight into the wall rather than a power strip.
What humidity is best for sleeping?
Between 40% and 50%. That range keeps dust mites and mold in check without drying out your throat, eyes or sinuses. Below 35% you may wake up congested, so do not set it too low.
Will a dehumidifier keep me awake?
A compact thermoelectric unit is close to silent. A compressor unit hums like a refrigerator, roughly 40–50 dB; many people find that steady sound fine or even soothing, while light sleepers may prefer to run it in the evening and switch it to sleep mode overnight.
What size dehumidifier do I need for a bedroom?
A small bedroom with mild dampness does fine with a compact unit. For a bedroom up to about 500 sq ft with wet windows every morning or a musty smell, a 20–22 pint compressor unit is the practical size. If the bedroom is in a basement, size it like a basement.
Does a dehumidifier help with allergies?
It can. Dust mites need humidity above roughly 50% to thrive and mold needs about 60%. Keeping a bedroom near 45% makes both much less comfortable. A unit with a HEPA filter also traps some airborne particles.
