As winter lingers and cold weather combined with home heating system operation dries out indoor air, you might be considering a humidifier for your home. By infusing moisture into the air, this appliance can significantly improve air quality and reduce a multitude of health risks. 

Home humidifiers deliver moisture with one of four different types of technology and come in various sizes to suit different living spaces. The best one for your home will produce comfortable indoor air all winter long. 

Why is the air dryer in the winter?

The chill of winter air comes with another unpleasant feature — it has a drying effect. That’s because cold air doesn’t hold moisture levels as well as warm air. Unlike the air on a summer day when humidity is noticeable, moisture dissipates quickly in cold winter weather. What’s more, the heat from a furnace exacerbates the problem. 

Benefits of using a humidifier 

According to the Mayo Clinic, dry indoor winter air can result in several uncomfortable conditions, but using a humidifier can help. One of the first signs that the air inside of a home is too dry is the development of skin that’s itchy, flaky or cracked. Humidifying air is hydrating, and soothes the symptoms of dry skin. Dry air can also cause a stuffy nose, nosebleeds, dry mouth, snoring and can even aggravate asthma. Improved breathing is another benefit of using a humidifier. 

Humidifier maintenance

To get consistent results and prevent the buildup of mold and bacteria, it’s vital to clean a humidifier frequently. Change the water daily, and clean the unit about every three days with a solution of hydrogen peroxide or vinegar. Change filters according to the manufacturer’s instructions. When a humidifier isn’t being operated consistently, it should be dried thoroughly in between uses. 

Types of humidifiers 

Many modern humidifiers distribute fine mist moisture into the air with either ultrasonic waves or fan-driven evaporation. Both types are highly reliable at increasing humidity levels. 

Impeller and steam humidifiers are also available. Impeller models produce a lot of moisture but can be messy. Because steam humidifiers emit warm moisture into the air, they are often preferred by those suffering from colds or respiratory viruses. However, the hot steam can cause burns, so this type of humidifier should not be used in homes with children. 

Large and compact models are available. Most manufacturers provide information about the area that can be humidified by a particular model in the product description.
