What is the White Dust Coming From My Humidifier?

By April 21, 2014 April 1st, 2015 Humidifier, Hydronics, Residential


You may be enjoying the better air in your home thanks to your humidifier, but you may also have noticed some kind of white dust settling on things nearby. This might cause you to think about turning off the humidifier and going back to living with a dry throat and itchy skin. But don’t unplug that humidifier just yet! That white dust is actually harmless. Take it from us (experts at installing water heater Rochester NY).

The white dust you see is simply a by-product of the water you are using. There are minerals in our water that occur naturally. When the water goes through the humidifying process and is essentially vaporized, those minerals take on a solid form and look like white dust. It is perfectly safe and will cause no issue with breathing or air quality at all. If anything, it may just mean you have to dust more frequently. If you have a high amount of minerals in your water, and more white dust as a result, you may have to clean the machine and change the filters more frequently.

One way to avoid having to deal with any white dust is to use distilled water in the humidifier. You can also invest in better filters to trap any residual minerals and white dust.

White dust is nothing to worry about and can be easily dealt with. If you have any questions about your humidifier or if it is emitting anything you aren’t sure about, even beyond white dust, don’t hesitate to ask the professionals at High Performance Heating, Cooling and Hydronics.
