If you're experiencing sneezing, dry eyes, scratchy throat, and coughing for what seems like the entire day — and not just when you're outside — chances are you probably have allergies. Seasonal allergies (also known as hay fever and allergic rhinitis) happen when you're exposed to airborne substances, such as pollen, that your body is sensitive or allergic to and that only appears during certain times of the year, according to the American College of Allergy, Asthma, and Immunology. However, if you suffer these types of symptoms year round, you're likely also allergic to indoor triggers, such as pet dander, mold, and dust mites.

The good news is that investing in a humidifier could help ease some of your allergy symptoms. During winter, dry indoor air is often the cause of irritated sinus passages; and in the summer months, stale, dry air from air conditioning can also cause sinus irritation. These types of dry air can exacerbate allergies and colds, says Purvi Parikh, M.D., an allergist and immunologist with Allergy & Asthma Network. But the moisture from a humidifier works to soothe dry sinus passages and helps you to breathe better.

How exactly? The short answer: Humidifiers add moisture back into the air. More specifically, they work by releasing water vapors and steam into the air, which helps increase humidity levels and mitigate breathing issues (translation: if you have allergies or cold symptoms, it helps to break up mucus and dry up stuffy noses). And FTR, humidifiers can also help remedy winter skin woes, such as dry skin and chapped lips, since they boost moisture in your home. (Related: Is It a Cold Or Allergies?)

There are five common types of humidifiers: cool mist, warm mist, ultrasonic, evaporative, and vaporizers. All types work by either letting warm air out or releasing cold mist. Cool mist humidifiers usually use less electricity since the water is not heated before it's dispersed, they are safer to have around pets and children (no hot water accidents), they can be slightly noisier than other humidifier types since they use a fan to push out moisture, and they can cause the air to feel chillier in your home, making them ideal for warmer climates.

Warm air options use an internal heating element that boils water before releasing it into your environment as an invisible mist, making them great for winter months or cold climates. They are thought to make the home healthier, since the boiling process kills waterborne bacteria and mold, preventing them from entering the air you breathe. Because they don't have an internal fan, they operate quietly (although you'll still hear a bubbling sound), and they can be harder to clean, thanks to mineral deposits left behind during the boiling process.

The downside of humidifiers is that dust and mold from the devices could cause more harm than good when it comes to indoor allergies, warns Dr. Parikh. Because dust mites grow where there is moisture, humidifiers can create the perfect environment for them to prosper. To prevent dust mites and maintain proper humidity levels to help with allergy symptoms, you should keep the humidity level in your house between 40 and 50 percent, according to the American Academy of Allergy, Asthma & Immunology. Mold spores can also be irritating to people with allergies, so it's important to clean your humidifier daily and change the filter per the manufacturer recommendation, so that mold does not grow in the unit and blow into your home, says Dr. Parikh.

While there is no evidence that humidifiers can help with COVID-19, there was a study done in June 2020 focused on the Greater Sydney area of Australia during the early epidemic stage of COVID-19 that found an association between lower humidity and an increase in community transmission. Research showed that lower humidity levels caused airborne COVID particles to stay in the air longer — so it couldn't hurt to introduce a humidifier into your home to boost humidity levels to protect you from both allergens and, potentially, coronavirus.

One reviewer wrote: "For weeks I have been waking up in the middle of the night. I would have trouble with my nasal passages being so dry and congested that I would be forced awake to clear my nose. In the winter months, the heater would dry the air. Now the warmer months, the fan and AC do the same. The first night of using a humidifier for the first time showed a little improvement in my dryness and allowed me to sleep mostly uninterrupted. Now on the third night, I didn't have any sleep interruptions at all. My nasal passages have remained clear. It's only been a week and I plan on running it continuously for the foreseeable future."

We live in southern AZ and humidity levels can be 3 percent... the Venta keeps all of us moist and breathing clean air. I'm addicted to essential oils and diffuse lots throughout the house. Peppermint in the Venta has made my asthma inhaler a thing of the past... I just can't put too much in or everyone's eyes burn. Great product."
