Custom Filters Direct 19.5x21x1 air filters help keep your house and business clean by trapping dust and dirt particles. They ensure that the air circulating through your HVAC system is clean and free from contaminants, like dust, pollen, mold, and bacteria.

In addition to keeping your home and business clean, our air filters also help to protect against allergens and prevent damage to your heating and cooling equipment. Custom Filters Direct 19.5x21x1 air filter will proactively remove high levels of allergens and particles from your environment. When the air from outside passes through the filters, they block more than 90% of the harmful particles while allowing the clean air to pass through.

Our AC and furnace air filters are designed with an electrostatically charged filter media which takes the filter to the next level. This media creates a strong electric charge that enhances the filter’s ability to trap air pollutants.

Though these filters are designed for better airflow and longer-lasting filtration, eventually dust begins to accumulate on the surface of the filters and block the pores of the filters. And once the filters get blocked, they don’t allow the clean air to pass through and this makes your HVAC unit work harder. We recommend you to change your air filters every 60-90 days to maintain indoor air quality.
