1Furnace or air handler-mounted humidifiers
Safety first: Before performing any kind of maintenance or repair to your humidifier, turn off the water to the humidifier and turn off power to the furnace or air handler.
2Always have a clean filter/pad in place.
Annually, replace the humidifier pad, filter or element. Once scale and mineral deposits build up, it’s usually impossible to clean them properly. It’s best to replace. Enter your humidifier’s model number
to find the pad, filter or element for your model.
3Clean it at least once annually.
Scale, rust and hard water deposits will accumulate inside of your humidifier and diminish the amount of moisture the humidifier can put into the air. Follow your humidifier owner’s manual for disassembly and cleaning instructions.
4Periodically check for leaks.
If your humidifier is leaking water on the ground, turn off the water supply until the reason for the leak is discovered and corrected.
5Additional cleaning tips
For furnace-mounted reservoir-style humidifiers
• Over time, calcium and mineral deposits will encrust the water reservoir (a.k.a. water container or water bucket) and the water wheel on reservoir-type humidifiers. This may also lead to the growth and harboring of bacteria. Thoroughly clean out the reservoir before and after the heating season and throughout the heating season, add an anti-bacterial solution monthly.
• At the end of each heating season, remove the float assembly and water wheel, inspect them for damage and thoroughly clean them using anti-bacterial treatment designed for humidifiers. Alternatively, use white vinegar for the job.
For Portable or console-style humidifiers
• A few times per season, clean out the water reservoir to remove mineral deposits. Add an anti-bacterial solution to curb the growth of bacteria.
