How Often Should I Change The Air Filters In My Home?

Air Filters. If you have an HVAC system in your home, your air filters are an all -important, but well hidden component of your home’s indoor air quality. If your air filters aren’t changed on schedule, they can cause damage to your entire HVAC system, as well as impair the quality of air within the home. Today we will go over some basic guidelines about how often to change your air filters. However, these are only broad guidelines, so be sure to adjust how often you change them to how frequently they get dirty.

Every 6 Months

Are Your Air Filters Clean?

If you are a non-smoker, and you keep your home squeaky clean at all times, and have very little dust in the home, that’s a good thing for your air filters. Also, if you don’t have children or pets, your air filters may thank you for that as well. Last but not least, if you don’t open your windows very often too, your air filters probably don’t have much work to do. If all of the above apply to you, you might not need to change your air filters for 6 months at a time. However, be sure to check them every 3 months to make sure they are still in good condition.

Every 3 Months

If you are a non-smoker, and keep your home moderately clean, but you have children and like to leave the windows open on occasion, you may need to change your filters more frequently. Children and open windows can track in dirt and dust, which eventually gets picked up by the air filters. If this sounds more like you, then changing your filters every 3 months is probably a good guideline to follow.

Every Month

Now, if you smoke, or have pets, or both, you can expect your air filters to need a bit more attention. Adding children, open windows, dust and other factors into the equation will require extra attention as well. In this type of household, it is often best to change the filters monthly, or to at least check them monthly to make sure they are still functional.
