Humidifiers are devices that add moisture to the air to prevent dryness that can cause irritation in many parts of the body. They can be particularly effective for treating dryness of the skin, nose, throat, and lips, and can ease some symptoms caused by the flu or common cold. Humidifiers can also be used to relieve symptoms related to health conditions such as allergies, sinusitis, and eczema.

Here are some of the benefits of using a humidifier:

• Moisturize skin and lips
• Protect throat
• Soothe sinuses
• Halt the spread of flu germs
• Ease symptoms of illness
• Alleviate snoring
• Promote healing
• Prevent dryness
• Improve indoor air quality
• Help houseplants thrive

There are five main types of humidifiers: central humidifiers, evaporators, impeller humidifiers, steam vaporizers, and ultrasonic humidifiers. The type of humidifier you choose depends on your preferences, budget, and the size of the area you want to add moisture to. Humidifiers are often classified as console or portable/personal. Console units are meant to add moisture to the entire house, while personal (or portable) humidifiers are the smallest and are the best choice if you need a humidifier while traveling.

It is important to note that overusing humidifiers or not cleaning them properly can potentially worsen respiratory problems and cause other health conditions. It is recommended to keep humidity in the home between 30 and 50 percent. If you are experiencing bothersome symptoms, talk to your healthcare provider to figure out if a humidifier may help you.
