Health Benefits of Humidifiers
Using a humidifier in your home or office can provide a variety of health benefits. Humidifiers add moisture to dry indoor air, which can alleviate respiratory issues, skin irritation, allergies, and more.
Alleviate Respiratory Problems
Dry air can irritate and inflame the respiratory tract, worsening conditions like asthma, allergies, sinusitis, bronchitis, and colds. Humidifiers can add much-needed moisture to the air, providing relief for sore throats, congestion, coughs, and other respiratory issues. Key benefits include:
- Soothe irritation and inflammation in the nasal passages, throat, and lungs
- Loosen mucus and clear congestion in the airways
- Prevent dryness that can lead to further complications
Moisturize Skin
Dry indoor air can dehydrate your skin, causing flaking, itching, cracked lips, and even fine lines and wrinkles. By adding moisture back into the air, humidifiers can help skin stay hydrated, supple, and healthy. Benefits include:
- Prevent dry, flaky, itchy skin
- Minimize appearance of fine lines and wrinkles
- Soothe cracked lips and cuticles
- Reduce facial redness and inflammation
Lessen Allergy and Sinus Symptoms
Humidity helps minimize the spread of allergens like pollen, dust mites, pet dander, and mold spores. This can provide relief for allergy and sinus issues like:
- Runny nose
- Sneezing
- Itchy, watery eyes
- Stuffy, congested nasal passages
By keeping these allergens from circulating as much in the air, humidifiers allow you to breathe a little easier.
Prevent Nosebleeds
Dry air can dry out and irritate the sensitive membranes inside the nose, which can crack and bleed. Humidifiers add needed moisture to the air to keep nasal passages properly hydrated and prevent painful nosebleeds.
Help Ease Cold and Flu Symptoms
Humidifiers can provide added relief when you’re battling a cold or the flu, including:
- Soothe sore throat pain
- Loosen mucus and ease congestion
- Prevent dehydration
Proper hydration is key to helping your body heal more quickly when sick.
Improve Sleep
Dry air can irritate airways and make breathing difficult, disrupting sleep. Adding humidity to the air can help you sleep more soundly through the night. Other benefits include:
- Alleviate snoring and sleep apnea by clearing congestion in nasal passages
- Boost circulation for better night’s sleep
By reaping all these healthy benefits, humidifiers can be a beneficial addition to any home or office.

Types of Humidifiers
There are several different types of humidifiers, each with their own benefits and drawbacks. The main types of humidifiers are:
Warm Mist Humidifiers
Warm mist humidifiers work by boiling water to produce steam. The steam is then released into the air to increase humidity levels. Key features of warm mist humidifiers:
- Provide soothing warm moisture
- Heat kills bacteria in the water, reducing growth of mold and mildew
- Ideal for use in cold weather to add warmth and moisture to the air
- Models powered by steam vaporizers heat water to boiling point, while others use ultrasonic vibration to produce steam
For example, the Crane Warm Mist Humidifier uses an internal heating element to boil water and provide warm, bacteria-free mist into the air for up to 24 hours on low setting.
Cool Mist Humidifiers
Cool mist humidifiers work by dispersing room temperature water into the air as a fine mist. They do not heat the water. Benefits include:
- Provide cooler moisture, which some people find more comfortable
- Safer for use around children since the water stays cool
- Energy efficient - no heating element uses less electricity
- Great for warm weather when you don't want to add heat to a room
For instance, the Honeywell Cool Moisture Humidifier disperses a cool, invisible moisture to increase humidity levels without adding warmth to a space.
Evaporative Humidifiers
Evaporative humidifiers use a fan to blow air through a wet wick filter. As the air passes over the filter, it picks up moisture. Key features:
- Wick filters are self-cleaning and minimize mold growth
- Very quiet operation
- No heat - provides cool moisture into the air
- Super energy efficient
The Essick Air Products EP9500 Evaporative Humidifier uses this technology to humidify spaces up to 900 square feet.
Ultrasonic Humidifiers
Ultrasonic humidifiers use high-frequency sound vibrations to create micro-fine water droplets that are dispersed into the air. Benefits include:
- No heating element produces cool mist
- Whisper quiet operation
- Smaller units work well for single rooms
- Easy to clean with detachable parts
The Pure Guardian H965 Ultrasonic Cool Mist Humidifier uses these sound waves to provide up to 70 hours of humidity on low setting.
Impeller Humidifiers
Impeller humidifiers use a rotating disk to fling water at a diffuser. The diffuser breaks the water into tiny droplets that enter the air. Features include:
- Budget friendly option
- Small units good for travel
- Produce cool moisture
- Can be noisy due to spinning disk and fan
The Holmes Mini Travel Mist Humidifier uses an impeller disk to provide moisture in rooms up to 250 square feet in size.
When selecting a humidifier, consider the humidity output, coverage area, ease of filling and cleaning, noise level, and other features that are important for your needs.
