When was the last time you replaced the air filters in your home? With poor air quality becoming a growing concern across the United States and Canada, you are probably more aware of your home’s air filters than ever before. Air filters help keep our home’s air clean and free of dust, dander, and pollutants. This not only helps us breathe easier, but it also keeps the HVAC systems in good shape and prevents them from experiencing potential damage due to the buildup of airborne particulates.
