What about media filters?

Media filters should be replaced once a year, possibly twice depending on your home. Homes with pets or smokers may need to replace media filters more frequently. Consider adding an alert to your calendar for six months after you install a new media filter. That way you can be sure to stay on top of regular filter changes and keep your family breathing easy all year long.
