Change Your Filters to Improve Your Indoor Air

It is important that air filters be changed regularly to ensure the best possible indoor air quality. The time between filter changes varies with filter type, system location and other environmental factors. Replacing filters regularly allows your HVAC (heating, ventilation and air conditioning) system to run at peak performance and can help minimize health risks caused by harmful airborne particles.


For residential applications, 1 inch pleated filters can last up to 90 days, and panel/fiberglass filters can last up to 30 days. For higher efficiency filters, such as air cleaners, the lifespan can range from 6 months to one year. However, it is best to monitor filters every 30 days to ensure that they don't need to be changed sooner. If the filter is dirty, then it should be changed.

Environmental factors and certain living conditions can drastically reduce the life of your filter. These instances include:
• Extreme outdoor temperatures (hot or cold)
• Heavy traffic
• Pets
• Smoke (Tobacco, Fireplace and Candle)
• Home remodeling/repair projects
• Dirty ductwork
