How often you change your air filter will influence not only the quality of air that you breathe, but it will also impact the health of your HVAC system.
That’s because an air filter is designed to operate effectively up to a certain point, depending on how much dirt, dust and pollutants it can hold. Expert recommendations on filter-change times vary, and a variety of factors within your home will influence how often you should change your air filter. Here are some general guidelines you should follow:
- Most experts advise that homeowners change standard 1″ air filters once a month when their A/C, heat pump or furnace is used on a daily basis. When you run your HVAC equipment intermittently, you may be able to extend that time frame to perhaps once every six weeks or every two to three months.
- If you have family members with allergies or asthma you may want to change your air filter more often.
- If you have pets in the home with dander or who shed, it’s desirable to change the filter frequently.
- When you’re conducting home projects that create dust and dirt, during that period of time, you should keep your eye on the air filter, as it will become fuller faster.
- There are Extended Life Air Filters that require changing less frequently and clean the air better than standard 1″ filters.
If you’ve never paid much attention to your air filter in the past, knowing when to change it can be daunting. However, it’s fairly easy to tell when you should change your air filter with a visual inspection. Simply remove the filter from the equipment and hold it up to the light. If it looks brown, dingy or it’s clearly dirty and full, change it out. Doing so will help you reap the benefits of regular changes, like better HVAC system health, as a dirty filter will begin to restrict airflow essential to its efficient operation, and good indoor air quality.
