One of the best ways to properly maintain your air conditioning system and overall indoor air quality at home is to check your air filter and replace it when it’s necessary. Air filters help prevent dirt, dust, dander, debris, hair, and other small particles from cycling through your home. They are responsible for making your home’s air much cleaner and more breathable.
However, you may be wondering, “How often should I change my air filter?” The answer to this question depends on a variety of factors, such as the amount of people and animals in your home, as well as the type of air filter your unit needs.
While it’s imperative to read the owner’s manual for your AC unit, the following are the general guidelines for how often you should change your filter:
- If you have multiple people or pets occupying your home, as well as allergies, you should change the air filter every 30 to 45 days.
- If you have multiple people and only one pet occupying your home, replace the air filter every 60 days.
- If you don’t have pets, but have a multiple people living in your home, replace your filter every 90 days.
- If you are single without any pets or allergies or if your home is seldom occupied, replace your filter every six to 12 months.
The quality of your air filter has a significant impact on your AC’s performance and efficiency. Regularly checking the filter can prevent or resolve issues which could have resulted in more costly repairs down the road.
