Looking for fall allergy relief? Your humidifier or dehumidifier could help!

Late October usually brings beautiful autumn colors and more comfortable autumn temperatures. Unfortunately, sniffles, sneezes and colds are often close behind.

“It’s a trifecta this time of year,” said David Stukus, M.D., a pediatric allergy and asthma specialist at Nationwide Children’s Hospital in Columbus, Ohio and associate professor of pediatrics at the Ohio State

University College of Medicine. “The most common cause is circulating viral infections as kids go back to school,” Stukus says. “The other would be changes in the weather pattern, which can cause worsening symptoms that are often preexisting. We have ragweed and mold spores, especially on rainy days and when the leaves collect in the fall.”

Things might not be much better indoors for those with dust mite or other environmental allergies. As temperatures drop and the windows are closed, those allergy symptoms can get worse.

Depending on the symptoms and cause, the course of treatment might include use of a humidifier or dehumidifier. Here’s how each could help:

Humidifier: “For people with chronic nasal congestion or postnasal drip, we’ll often recommend running a humidifier in the bedroom at night,” Stukus says. Only use water in the dehumidifier, he says. “We never recommend putting any kind of medicine, herbal treatment or essential oils inside a humidifier,” Stukus says. “Diffusing medicine through these products can cause irritation of the skin, nose and lungs.” The American Academy of Allergy, Asthma and Immunology recommends only using distilled or demineralized water in humidifiers, as the minerals in tap water can increase bacteria growth and produce a dust that makes symptoms worse. Use the humidifier in the room in which you spend the most time. Typically, that means the bedroom. Clean the humidifier regularly to avoid mold and mildew development, which can make symptoms worse.

Dehumidifier: Those who have allergies to dust mites will want to aim for a less humidity, as the microscopic mites tend to thrive in a humid environment. A dehumidifier can help. “If they have high humidity levels in their home or obvious mold growth, that would be a good indication to get a dehumidifier,” Stukus says. AAAAI suggests keeping the humidity level in your home between 30 and 45 percent.

There’s no single course of treatment for allergies, so it’s essential to see a physician who can conduct the proper examination and testing to find out what’s causing the symptoms. Don’t try to self-diagnose. “[Diagnosis is] complicated and highly individualized,” Stukus says. “You really need to know what’s going on with that person to provide the best course of treatment.”

Looking for a way to remove some of the pollen and allergens from the indoor air? Room air cleaners certified through AHAM’s certification program have been certified and verified by an independent laboratory, assuring consumers that the product will perform according to the manufacturer’s product claims for suggested room size and the reduction of three common household particulates: tobacco smoke, dust and pollen, commonly referred to as the Clean Air Delivery Rate (CADR).
