Proper maintenance of your AprilAire Whole-House Humidifier is essential to avoiding dry, winter air at home!

How to Change Humidifier Filters

AprilAire Water Panels are filters for humidifiers that help your home maintain optimal humidity levels by helping your unit convert water into vapor. To keep your system performing at its best, it’s recommended to replace AprilAire Water Panels regularly.

First, identify which AprilAire Water Panel your unit requires so you can secure the correct replacement: Either a 10, 12, 35, or 45 Water Panel. AprilAire 10, 12, and 35 Water Panels should be changed once per heating season, and the AprilAire 45 Water Panel should be changed twice per heating season.

Once you’re ready to change the filter, turn your humidifier control dial to the ‘OFF’ position as well as turn off your water supply, remove the cover to your AprilAire Whole-House Humidifier, pull out the old AprilAire Water Panel, and drop a new one in! Though this how-to advice is rather simple, it’s important to note that each unit can have unique steps you might encounter along the way.

To be sure you’re installing your AprilAire Water Panel correctly, use the instructions printed on the back of the carton—just one perk of using genuine AprilAire replacement parts!
