Find the Right Size Humidifier for Any Room
Plus, the best models from Consumer Reports' tests
Keep Goldilocks in mind when shopping for a humidifier. You don’t want one that’s too big and releases too much moisture into a room or one that’s too small to do much good. You want a humidifier that’s just the right size.
Too little moisture can make your skin feel dry and itchy, but too much can breed dust mites and mold, and trigger allergic reactions. When a room feels clammy or there’s condensation on the windows, there’s too much moisture.
“Since high humidity leads to its own set of problems, avoid buying the largest humidifier and instead pick the one designed for the size of your space,” says Misha Kollontai, the engineer who leads Consumer Reports’ humidifier testing.
Ideally, the humidity level in your home should be between 30 and 50 percent, according to Energy Star. In colder areas during the heating season, it should range from 30 to 40 percent to prevent window condensation.
