How Often Should I Change My Air Filter At Home?

Depending on how much traffic your home or business receives can help determine how often your air/furnace filter needs to be replaced. Replacing your filters regularly can help reduce airborne contaminants and lower your energy bills (estimates based on a 1” standard pleated filter.)

• Lower traffic homes/apartments (single occupant/no pets): every 3-4 months
• Moderate traffic homes (no pets): every 90 days
• Moderate traffic homes with pets: every 60 days
• Heavily trafficked homes with 2+ pets/occupants with allergies: every 30 days

Why Should I Change My Air Filters?

• Air filters should be changed out regularly to help maintain a healthy IAQ (indoor air quality) and ensure that your HVAC system continues to run properly. When your air filter isn't changed out routinely it can become dirty and clogged which restricts airflow. when the airflow is restricted, your HVAC unit must stay on longer and overwork to cool or heat your home or office, which can lead to costly maintenance repairs.
