What are Humidifiers?

As the name implies, humidifiers are devices that release steam into the air. They’re designed to increase moisture levels (humidity). Different types of humidifiers exist on the market today, such as central humidifiers, steam vaporizers, and evaporators.

The purpose of humidifiers is to help relieve discomfort caused by dry indoor air, including bloody noses and cracked lips.

Do Humidifiers Cause Mold?

The bottom line is yes, humidifiers can cause mold. Because moisture feeds mold development, and humidifiers increase moisture levels, mold can easily grow from their use.

But this doesn’t mean that humidifiers will always cause mold growth. In fact, mold growth from a humidifier can easily be prevented with the right dehumidifier maintenance.

Humidifier Maintenance Steps to Take to Prevent Mold Growth

In order to prevent mold development from humidifier use, we recommend following these steps:

Change Humidifier Water Regularly

Certain deposits can develop inside your humidifier if you don’t change the water often. Make sure to empty the tanks and refill them every day, if possible.

Use Distilled Water

Tap water contains minerals that promote bacterial growth. By using distilled water, which has lower mineral content, you can reduce the risk of mold development significantly. You can also reduce the risk by using demineralization cartridges or filters.

Clean Your Humidifier Frequently

Every three days, you should unplug your humidifier and clean it. Remove mineral deposits from your humidifier’s tank or other parts with a 3% hydrogen peroxide solution available at most pharmacies.

Read the humidifier’s manufacturer notes. They may mention using another disinfectant instead of hydrogen peroxide.

Replace Your Old Humidifier

If your current humidifier is an older or outdated model, you should consider replacing it. Older humidifiers can build deposits that are difficult to remove and can promote mold growth.
