Filter King AC & furnace filters aren’t the typical fiberglass filters that need to be replaced every 30 days. Our filters can typically be used for 3 to 5 months before requiring to be changed. Naturally, a variety of things influence filter lifespan.
Some of the factors that influence your filter’s life include outdoor air quality, whether pets are in the home, and how well your HVAC system is maintained.
Your air filter becomes clogged over time by trapped particles, preventing airflow. The efficiency of the HVAC filter declines. Your system must work harder to heat and cool your home.

Filter King 19.5x21x1 size air filters are necessary parts of your home air systems, used to keep incoming airflow clean and healthy. The fresh air cycling into your home keeps your home feeling comfortable and safe, but the air pumped in is not necessarily safe. Much of the time, air coming in needs cleaning and filters are able to allow airflow to pass while keeping it free of irritants. Over time, your home avoids pollution but the particles that were blocked begin to build up and cause a problem for your home over time.
The indoor air quality of your home often depends on fresh air coming in, preferably clean and free of allergens and pollutants. When the air filters in a system become dirty then the resulting blockage is a problem for your problem as a whole. Dirty air filters are unable to properly process airflow effectively. The lack of incoming airflow leads to problems with dryness and stagnation throughout your home. Your air systems are also strained as they try to push airflow through the blockage, increasing home energy usage.
The air filters in your home are better clean, helping you avoid unnecessary billing and mechanical damage.
