Humidifier Maintenance Tips

Cleaning

  • You need to clean your Humidifier every year, because it builds up scale, rust, and hard water marks as it operates.
  • When your humidifier's pad or filter gets covered with hard water scale, you probably won't be able to get it perfectly clean again. It's best to just replace it each year. Visit RepairClinic.com for replacement humidifier pads and filters.

Float assembly

  • If you have a reservoir-type humidifier, the float assembly may get stuck while sitting unused all summer. To avoid this problem, remove the float assembly after each heating season and thoroughly clean and inspect it. If it's too heavily covered with minerals to clean properly, or if the float part has a leak and is filling with water, causing your humdifier to stop working, replace the float assembly.
  • For cleaning, try vinegar, or a specialized cleaner for humidifiers available at RepairClinic.com.

Water reservoir

  • Over time, the water reservoir on reservoir-type humidifiers gets encrusted with calcium and other minerals. It may also begin to harbor bacteria.
  • Use a cleaner and anti-bacterial solution to clean the reservoir completely at the start of the heating season and again at the end of the heating season.

Bacteria control

  • Bacteria can grow in the standing water reservoir of your humidifier and become airborne whenever the furnace blower is on. You can kill this bacteria within the humidifier.
  • Use a humidifier cleaner and anti-bacterial solution to clean the reservoir completely at the start of the heating season and again at the end of the heating season.
