Dry air in the home and office can lead to dry skin and irritated sinuses. A humidifier can help with these problems by adding moisture to the air.
Humidifiers may relieve symptoms of eczema and allergies. However, people should use these devices with care, as they can increase exposure to dust mites and mold spores. Easy-to-clean humidifiers may help people run them effectively and efficiently.
Individuals need 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.

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.
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.
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 because moist air can stop the skin from drying out. They can also help ease the symptoms of allergies and sinus problems. 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, clean humidifiers twice per week and change the filter regularly.
