Is the air in your home stale, humid, and muggy? Does it trigger flare-ups in your allergy symptoms or breathing problems? Marc Meth, M.D., an allergist based in Los Angeles and is part of the American Academy of Allergy, Asthma & Immunology, tells Verywell Health that dust mites and mold are the most common indoor allergies and they thrive in conditions of high humidity levels. Dr. Meth says a dehumidifier can significantly “inhibit dust mite and mold growths” which will help people with allergies and asthma breathe easier and live healthier.

Dehumidifiers are a great solution to balancing your air quality. These machines keep your home, clothes, and furniture fresh and dry. However, Dr. Meth warns dehumidifiers aren’t for everyone. They can be harmful to people with very dry skin who need more moisture in the air. “I recommend that people should keep humidity levels lower than 50% and that people clean out their dehumidifiers regularly to prevent mildew and bacteria growth,” Dr. Meth advises. 

Here are the best dehumidifiers on the market.

Best for Dry Skin: Waykar Dehumidifier

 Waykar 2000 Sq. Ft Dehumidifier

A dehumidifier isn’t for everyone. For people who suffer from dry, sensitive skin, a dehumidifier could make skin conditions worse as it removes excess moisture in the air. Dr. Meth says, “A dehumidifier is a bad idea for someone with bad skin—they usually benefit from having a more moisturized environment, but that can promote dust mite growth.”

If you’re a person with sensitive dry skin and suffer from allergies, it’s best to seek out a dehumidifier where you can control the humidity level. Waykar’s dehumidifier is a great option because you can control the amount of humidity in the room from 30 to 85%—though Dr. Meth advises the level in a room should be under 50%. By playing around with the humidity levels you can find a sweet spot where your allergies will subside, and your skin won’t dry out.

What to Look for in a Dehumidifier

Humidity Level:

If your home is severely moist and muggy, it is best to use a dehumidifier that can remove a higher quantity of water from the atmosphere a day and has a large water container, so you don’t have to fret about constantly emptying it out. If your home’s air conditions aren’t as severe, it is better to seek a miniature dehumidifier to prevent drying out your home.


Basements, attics, garages, and other large spaces will all require bigger dehumidifiers. There are plenty of options on the market that remove enough moisture from the air without taking up too much space in your home.


Many complain that dehumidifiers are noisy and are constantly whirring due to their compressors and fans. If noise is a breaking point for you, try units that are designed to be soundless.
