With winter comes freezing temperatures, biting winds, snowstorms galore and, the worst of all, dry skin. When the humidity drops from the air, it's palpable. And dry skin isn’t just limited to outdoor experiences. With every door and window sealed shut to protect you from the cold, the air indoors lacks moisture, too.

Luckily, humidifiers exist as a solution to that problem. Shop TODAY asked a few doctors about what humidifiers do, when to use them and tips for when you’ve brought one home.

What does a humidifier do?

A humidifier’s job is to add moisture to the air, explained Dr. Merritt Fajt, a physician who specializes in allergy and immunology at the University of Pittsburgh Medical Center.

“Using one can help make your skin, lips, nose and throat not feel as dry,” added Dr. Emily Pennington, a pulmonologist at Cleveland Clinic in Ohio. Simply put: it’s a comfort thing. It can also help with irritated sinus passages, Fajt added.

When to use a humidifier

Fajt says people most commonly use a humidifier during the winter. “The air is just so dry inside and people are trying to have their skin not be so dry,” she explained. “Unfortunately, that’s also the time when…inside allergens are the highest because people are having their windows closed because it’s so cold outside.”

Dr. Jonathan Parsons, director of the Asthma Center at Ohio State University Wexner Medical Center, has one warning: If you have a breathing disorder, be very careful. Over-humidifying the room or failing to clean the unit properly can lead to the growth of mold, mildew, bacteria and dust mites, which can exacerbate allergies, asthma or other pulmonary conditions, both he and Fajt advised.

If you're looking for something to specifically filter the air, look into getting an air purifier.

Tips for using a humidifier

Pennington recommended cleaning a portable humidifier every 72 hours — this requires emptying out the water daily, scrubbing the tank to rid any built-up film and rinsing the base. Fajt echoed similar sentiments, saying it’s important to clean your humidifier and change the filter on a regular basis because, like Pennington noted, not cleaning it properly can lead to potentially harmful side effects. “They think that they’re trying to do a good thing, but they’re actually blowing mold into [the] home,” Fajt said.

You’re also best served using distilled water. Otherwise, naturally occurring minerals can build up in the tank and compromise air quality, Fajt and Pennington noted.

Another word of caution: When it comes to the vapor, less is more. Ideally, you should try keeping humidity between 30 percent and 50 percent, advised Pennington. Some models have built-in humidity monitors. If they don't, Parsons suggests buying a room hygrometer.

If you're looking for the best humidifier for the bedroom, or for anywhere else in the house, here are 15 that will get the job done.
