How often should you really change your filters? It’s one of the most common HVAC questions, yet the answer often feels frustratingly vague. You might hear recommendations like "every three months," but in commercial and industrial settings, one size never fits all. At Joe Fly Co., we know that smarter filter schedules can save time, money, and effort while enhancing air quality. Here’s a detailed guide to help you move beyond guesswork.

The primary purpose of HVAC filtration is to protect the HVAC equipment and maintain its performance by preventing the buildup of dust, dirt, and debris on components such as coils, fans, and motors. Additionally, HVAC filters help remove airborne particles such as pollen, pet dander, mold spores, bacteria, viruses, and other contaminants that can affect the health and comfort of occupants.
