Find a quiet dehumidifier. Have someone test the dehumidifier in front of you and judge whether you can sleep with that noise or not.
Noisy dehumidifiers often don’t allow you to sleep comfortably in your bedroom.
Some dehumidifiers come with an auto-shutoff and auto-start feature that tells the dehumidifier if the collection pan is full or missing. Get a dehumidifier with these features if you don’t want to constantly verify the contents of the collection pan.
The auto-start feature starts the dehumidifier again when it detects you have placed the emptied pan back in the housing.
Just like a thermostat regulates running temperature, a humidistat regulates the target humidity a dehumidifier reaches. Dehumidifiers without this feature might make the room uncomfortably dry or too wet for a person with allergies.
Mold needs a level of humidity between 65 and 99 percent to thrive, according to the Health and Energy website. Placing your dehumidifier at the center of your bedroom with a humidistat set to 55 percent or lower helps prevent a mold infestation.
If you or an occupant smokes in the bedroom, you should get a dehumidifier that also deodorizes the room, neutralizing the smell. Even if no one smokes, other odors from clothing and mold might have gotten into the room and need deodorization.
Dehumidifiers often come with filters that don’t deodorize, but the manufacturer of the dehumidifier might offer such a filter for purchase.
