You should change the air filter in your furnace every 30 days to 3 months depending on the quality of the filter. It’s important to have the correct size filter in your furnace because the air filter captures the dust that circulates in your home. If you have not changed your filter in the last 30 days to 3 months, replace your filter immediately!
