What does my furnace filter do?

If you’re wondering why it’s so importantly to change your filter often, it’s important to understand what a vital job filters have. High efficiency furnace filters can remove up to 90 percent of mold spores and pet dander—which means pet owners should change their filters more frequently. The electrostatically charged fibers in these filters act like a magnet for allergy causing soot, smog, dust, and pollen. They can also help extend the life of your furnace.

How often should I change my furnace fillter?

Most HVAC experts recommend changing your filter alt least once every three months, but serious allergy suffers and pet owners will experience air quality benefits by changing their furnace filter once a month. With single filters priced at up to $15, the cost of regular replacement can add up. That’s where bulk buying comes in.
