Do I really have to change my air filter often?

Yes. If your return duct and return grille are properly sized, we recommend that a standard pleated filter is replaced every month. Many home improvement stores offer 3-month and 6-month filters. While these filters do catch particles, they also get clogged and choke your HVAC system’s air stream. If an HVAC system cannot properly breathe, it will struggle to heat or cool. It will also add strain to the system, which will increase your electric bill and increase the possibility of failures.
