Have you changed your furnace filter lately?
Changing the air filter in your furnace regularly will prevent dust, dirt, mold spores, soot, bacteria, and allergens from building up in the air inside your home. Changing your furnace filter is a very simple way to keep your indoor air clean and avoid costly repairs to your heating system.
In general, this is how often changing furnace filters needs to be done:
- For 1- to 2-inch filters, replace them every 1 to 3 months
- For 3- to 4-inch filters, replace them every 6 to 9 months
- For 5- to 6-inch filters, replace them every 9 to 12 months
