Before we get started though, we need to answer the question…

Do whole house humidifiers cause mold?

The short answer is, they shouldn’t. As long as you keep your relative humidity below 50% you should be able to prevent mold growth. Invest in a digital hygrometer to keep tabs on the humidity in your home. Check the hygrometer periodically and adjust your humidity levels up or down based on that.

It is possible to have some water condense on your windows during very cold weather. It’s the same idea as when water gets on the outside of a glass of ice cold water. Unfortunately, this can show up even with the best whole house humidifier. The condensation is unavoidable since the air in your home does need humidity in it. This can be frustrating because the air in your home can be too dry while also seeing this condensation on the windows.

If mold does develop on your windows, there are multiple ways to clean it off. Check with the manufacturer’s recommendations to see how to handle this. Different materials in the frame or and coatings on the glass may be damaged by stronger cleaners.
