Dry air in the home and office can lead to dry skin and irritated sinuses. A humidifier can help with these issues by adding moisture to the air.

A quick look at 7 of the best humidifiers

Humidifiers may relieve symptoms of eczema, allergies, and sinus issues. However, people should use these devices with care, as they can increase exposure to dust mites and mold spores. To help prevent mold, individuals should clean humidifiers twice per week and change the filter regularly — easy-to-clean humidifiers may help people run them effectively and efficiently.

A person needs to find a humidifier with enough power for their intended space, whether for the whole home or a small room. Modern humidifiers are available in a wide range of sizes and price points.

This list offers a range of possible options, but many more are available online. There is a wider range of humidifiers available to suit a single room than the whole home.

Health experts state that humidity levels in the home should range from 40–50% — greater levels than this can encourage dust mites. In contrast, humidity levels below this can irritate the skin, eyes, and throat.

Dealing with dry air does not usually require visiting a doctor. Instead, people can purchase a humidifier to increase moisture in the air and reduce the effects of dry air, such as eczema and dry skin.

However, these conditions may also worsen over time, and using a humidifier may not be enough. In this case, individuals should speak to a dermatologist to identify a course of treatment.

Some people also suffer from allergies. A doctor can present different solutions that may be more effective in combination with a good humidifier.

Below are some of the most common questions and answers about humidifiers.

What is the difference between a humidifier and a vaporizer?

Humidifiers release cool mist into the air, while vaporizers heat water and release steam into the air.

Both devices may benefit different health conditions.

Learn more about humidifiers and vaporizers.

Can I fill a humidifier with tap water?

Generally, manufacturers recommend using purified or distilled water.

This is because unfiltered tap water may contain higher levels of minerals or other particles. Minerals from hard tap water, in particular, can build up in the humidifier and may cause it to wear down faster.

How much humidity is too much?

The Environmental Protection Agency (EPA) states that indoor humidity levels above 60% are too high.

Is a warm or cool mist humidifier better?

Warm mist humidifiers tend to be quieter than cool mist products.

However, warm mist may be more drying than cool mist.

What type of humidifier is best for sleep?

A humidifier that keeps a comfortable humidity level in the room may be more ideal for sleep. Additionally, some people may prefer to invest in a humidifier that also helps remove bacteria.

Before buying a humidifier, people may wish to research models from trusted brands and read reviews. They also need to consider the size of the intended area that the humidifier will work in and the running time of the machine. Smaller models may not store enough water to run overnight.

Humidifiers can help prevent eczema symptoms as moist air can stop the skin from drying out. They can also help ease the symptoms of allergies and sinus issues. However, breathing in air that is too dry may irritate the eyes and nasal passages.

Without regular cleaning, humidifiers can also spread mold spores in the home. To help prevent mold, people should clean humidifiers twice per week and change the filter regularly.
