Can a Humidifier Cause Mold | Mold Due to Humidifier Use

humidifiers can technically cause mold if relative humidity is high enough

A humidifier can technically cause mold to grow in the room it’s in because it literally adds moisture to the environment.

However, this is not a common concern because the humidity level would have to be elevated for an extended period of time.

Mold growth due to humidifiers is abnormal because humidifiers that people use in their homes are only designed to hold so much water. Plus, they typically only run overnight.

It would take continuous refilling and constant use of the humidifier to raise the humidity of a room high enough to reliably grow mold.

Check Relative Humidity Levels When Using a Humidifier

Of course, an already humid area of the house with the addition of a humidifier can increase the chances of mold growth.

If you are concerned about moisture or humidity causing mold to grow in your home, you can simply get a humidity monitor or sensor. These typically cost no more than $10 online or at department stores.

As long as the house or room remains consistently under 55% RH (Relative Humidity), you are most likely in the clear.

Normal ranges for humidity are generally 30%-50%, so just be mindful if you are creeping toward the high end of things when using a humidifier.
