19.75x21.5x1 Air Filter

Filter King 19.75x21.5x1 size air filters are important parts of your home air systems, they clean airflow as the system pumps it in. Fresh air cycles into your home to prevent dryness and stagnation, when this process stops your entire home is affected. The indoor air quality of your home determines its safety and comfort. New air filters will help keep incoming airflow clean but in the process, become dirty themselves. Dirty air filters create a blockage that is difficult for airflow to pass, which in turn creates problems throughout your home.

The air filters in your home systems cleanse allergens and pollutants from passing airflow, keeping them from polluting your home. Over time, the air filters become covered in the incoming particles which leads to a blockage in the system. Allergens and pollutants are still unable to pass through, but neither is fresh air. The systems also begin to use more energy as they attempt to bypass the blockage and push airflow through. The resulting strain will eventually cause mechanical strain and an increase in energy billing that rises over time.

Your air filters need regular maintenance or there will be a gradual rise in costs over time as they become dirtier. We offer replacement 19.75x21.5x1 size air filters to help keep the airflow coming into your home fresh and clean.
