One of the most common questions we get is, \u201cHow often should I change a furnace filter<\/a>?\u201d A quick Google search will likely cause only more confusion as the answer will range from every month to every 3 months.<\/p>\n\n\n\n

Generally speaking, you should replace a standard HVAC filter every 3 months. However, this should be more frequent depending on certain factors. Let\u2019s go through some household circumstances that warrant a furnace filter change closer to the 1-2 month mark.<\/p>\n\n\n\n\n\n\n\n

What Does the Furnace Filter Do?<\/h2>\n\n\n\n

Contributing to the confusion about how often to change the air filter is the fact that many homeowners aren\u2019t aware of its true purpose. Contrary to popular belief, the air filter\u2019s main job is not to keep your home\u2019s indoor air clean\u2013it\u2019s to keep the inside of your HVAC system clean. Although a clean filter will help with air quality, it\u2019s not the main job of the filter.<\/p>\n\n\n\n

The HVAC filter is like your car\u2019s engine filter. It\u2019s designed to keep the most important components of the mechanical system free of dirt, dust, and debris. When you don\u2019t change the filter in a timely manner, mechanical issues inevitably arise.<\/p>\n\n\n\n

You may be wondering what could be in your home that\u2019s clogging up an air filter. For a car, it\u2019s easy to see how road debris and outdoor pollutants can get in the engine. For your home, it\u2019s things like dust, pet and human dander, and even things like pollen and outdoor contaminants that you bring home.<\/p>\n\n\n\n

When to Change the Filter More Often Than 90 Days<\/h2>\n\n\n\n

You should change the air filter more frequently in these situations.<\/p>\n\n\n\n
