The answer to 'lifespan of air filter' is that the typical lifespan of a standard HVAC air filter is between 1-3 months, depending on usage and environmental conditions. Air filters play a critical role in keeping your HVAC system running efficiently and maintaining good indoor air quality. As filters become clogged with dust, dirt, and other airborne particles, they restrict airflow and put extra strain on your HVAC system.
It's important to check your air filters regularly and replace them as recommended, usually every 1-3 months for standard pleated filters. Some factors that can affect filter lifespan include the number of people and pets in your home, whether you have any smokers, and how often windows are opened. Replacing filters on time can help extend the life of your HVAC equipment and improve indoor air quality.
