Dehumidifier for a bedroom: the size, and the noise question

In a bedroom, the noise and the glow of the display matter as much as the size. The EPA list says nothing about either.

How we pick

How we pick. Certified portable models rated 25–30 pints a day. That’s the top of the range ENERGY STAR suggests for a slightly damp room. Each one is sold by a store we link to. One pick per need: no app, EPA Most Efficient, and a Wi-Fi app. Within each need, the lowest yearly energy use wins, then the higher efficiency. The EPA list has no noise figure, so noise isn’t part of the rule. No 25–30 pint model with a Wi-Fi app is sold by a store we link to yet. So that pick is missing. Stores never pay for a place.

Questions

What people ask before buying

Which dehumidifier is quietest for a bedroom?

Public data can’t say. The EPA list covers 482 certified models and has no noise field, and this site doesn’t run its own sound checks.

Ask the seller for a figure in dB(A) and the distance it was taken from. Two figures taken at different distances can’t be compared. The quiet dehumidifier guide shows how to read them.

EPA list, Oct 15, 2026
Will it run all night?

Only as long as the room needs. Its built-in humidistat shuts it off at your setting and starts it again when the air gets damp. A lower setting means longer running.

Will it warm up the room?

A little. As it pulls moisture out, it slightly warms the air nearby, ENERGY STAR says. The air right next to the unit is the warmest. Does a dehumidifier cool a room? explains why.

What size and cost for a bedroom?

A bedroom that smells musty now and then needs 20–30 pints a day by the ENERGY STAR table. Certified 25–30 pint units use 285 kWh a year at the median of 39, about $52 a year at the U.S. average price.
