Generally every 2 - 3 months, you should change your home air filter. However, you may want to change your home’s air filter more often. During periods when you are using your HVAC system continuously, we recommend changing your home air filter monthly to maintain the best indoor air quality.

If you have multiple furry pets, heavy dust, keep your heat/AC fan on most of the time, have multiple smokers in the home, or often keep your windows and doors open, then you’ll want to change your home’s air filters once a month for the best air quality.

If you only have one furry pet, moderate dust, moderately keep your heat and AC fan on, have only one smoker in the home, and sometimes keep your windows and doors open, then change your home air filter every two months.

But if you have no furry pets, light dust, rarely turn your heat/AC fan on, no smokers in the home, and usually keep your windows and doors closed, then it’s probably okay to change all air filter every 90 days.

Look for the arrow showing airflow direction on the old air conditioner furnace filter and remember which way that it points. Make sure that you turn off your HVAC system to stop the airflow. Remove the old air conditioner furnace filter and discard it carefully so you don’t put the dust and other airborne contaminants back in the air. Write the date you install the air conditioner furnace filters on the place indicated on the side of the air filter frame. We strongly suggest you take the time to check your air filter from time to time to make sure it is not clogged. Remember, the pollutants you see on a dirty filter could be airborne particles you breathe – Change your air filters regularly and use our FREE Change Home Air Filter Reminder Service to help you!

Look for the arrow showing airflow direction, and install the new pleated air filter so the air flows in the direction of the arrows. Many air conditioner furnace filters are located at air return vents, where the air flows into the wall or ceiling. Note: On some custom size air conditioner furnace filters, the arrow may not be visible. If so, the air flows from the side without the metal mesh to the side with the metal mesh.
