Maybe you’ve passed the rows of humidifiers and dehumidifiers in your local pharmacy and wondered what the difference was. While many of us use “humidifier” and “dehumidifier” interchangeably, they have opposite functions—the former puts humidity into the air and the latter removes humidity. Both have their pros and cons, but a humidifier is particularly helpful during winter and spring, when many of us in colder climates may struggle to breathe or develop sore throats and allergies. Parade consulted Dr. Linda Dahl, MD, a member of the HealthyWomen Women’s Health Advisory Council and otolaryngologist with privileges at Weill Cornell Hospital, Northwell Lenox Hill Hospital, and Manhattan Eye and Ear Hospital, for more information on humidifiers—what they do, what their benefits are, and more. “A humidifier can make it easier for patients to breathe during colder months if they have asthma, allergies, and other chronic breathing issues like chronic obstructive pulmonary disease (COPD). It can also help singers stay hydrated,” Dr. Dahl exclusively tells Parade. “It can help relieve hoarseness during dry months and make breathing easier for those with asthma and allergies. It can help with dry skin as well.” Keep reading for more information on humidifiers straight from the experts—including the best humidifiers to shop for 2022.

What is a humidifier?

Not to be confused with a dehumidifier, a humidifier, according to Dr. Dahl is “a device that increases the moisture in the air.” In colder or dryer climates—specifically during the winter months—humidifiers really help increase the amount of moisture in the air, which in turn, can help people to breathe more easily. According to the American Academy of Allergy, Asthma, and Immunology, humidifiers also help with symptoms of allergies, which typically present themselves in the springtime. “[A humidifier] can be a small unit or centrally attached to the heating and cooling system in your house,” explains Dr. Monica T. Kraft, Allergist Immunologist at the Ohio State University Wexner Medical Center. “Humidifiers add moisture to the air by taking water and releasing it as a mist.” And while this is all-encompassing of what most humidifiers do, Dr. Dahl adds that there are different kinds of humidifiers, the four most popular being:

Who should use a humidifier?

Most of us can benefit from using a humidifier. But people who struggle with certain breathing ailments or even seasonal allergies may really want to consider investing in a humidifier because of the many benefits. “Depending on the circumstances, anyone who lives in a cold, dry climate can benefit,” explains Dr. Dahl. “In the winter, heaters dry out inside air even more. We are most comfortable when the inside humidity is 45 percent. Those with asthma, COPD, chronic sinus infections, and allergies can benefit from judicious use of a humidifier.” Even if you don’t have a diagnosis, Dr. Kraft adds, “signs of dryness can be chapped skin of the lips and nose, bloody noses, and a dry cough.” So, if you are experiencing those symptoms, you may want to consider using a humidifier, too. That being said, these machines do require some maintenance in order to ensure that the moisture it’s adding back into your environment isn’t contaminated. “It is very important to clean a humidifier daily to avoid the growth of bacteria and mold,” Dr. Dahl advises.

What are the health benefits of using a humidifier?

Humidifiers add moisture to the air in an environment, resulting in increased humidity. But how does this actually ease breathing struggles and other allergy-related symptoms? “A humidifier can decrease snoring, improve comfort, decrease nasal congestion, and increase the sensation of moisture, helping patients sleep and breath more comfortably,” Dr. Omid Mehdizadeh, MD, otolaryngologist (ENT) and laryngologist at Providence Saint John’s Health Center in Santa Monica, CA, tells Parade. Mehdizadeh adds that since added humidity can add moisture to one’s dry mucous membranes, humidifiers can help alleviate symptoms associated with cold, flu, allergies, nasal congestion, nose bleeds, and generally dry mucous membranes. According to Dr. Kraft, “Humidifiers can help soothe dryness and congestion of the sinuses and nasal passages which can occur with allergies and upper respiratory infections. Dry air can also trigger asthma symptoms, so adding extra humidity to the air with a humidifier can help these symptoms as well.” Sold on the humidifier and all its health benefits?
