How to Get Rid of White Dust in a Humidifer

Humidifiers are useful for helping to maintain a healthy balance of moisture in the air during the winter months. It is important to realize, however, that portable humidifiers require regular maintenance to make sure that they are not creating an unhealthy atmosphere with bacteria and germs that may grow within the unit.

If your humidifier forms a white dust on the unit after use, this is due to a high mineral content in the water you have been using in the humidifier.

To prevent this white dust from occurring, use only distilled water in a humidifier. To clean any white dust that already exists on your humidifier, read the following guidelines.
