How Often Should I Change My Air Filter?

A Standard 1″ air filter should be changed at least every 3 months, even as soon as monthly during heavy use times and if there is a lot of activity from people or pets. Media air filters, usually 2″ – 4″ thick, will last longer, usually around 6 months, because of a bigger surface area. These can be changed annually in some cases. Learn more about air filters >>
