Why should I change my filters?

How do we count the ways? There are so many reasons to keep your home air filters fresh. Clean air filters improve the quality of the air you breathe because they eliminate unwanted airborne particles—which means fewer germs and, as a result, healthier people. Maintaining clean air filters also prevents damage to your HVAC equipment, so there are fewer repair bills and your system lasts longer. Regular filter changes even reduce your overall energy bill. (Your HVAC system accounts for about half your bill, and keeping clean filters can reduce that bill anywhere from 5–15%.)
