Poor indoor air quality is the leading cause of breathing problems and can have a long-term impact on your family’s health and well-being.

Custom Filters Direct 20x23x1 air filters are designed to keep the indoor air quality fresh and clean by eliminating the most microscopic particles including smoke, bacteria, and virus carriers. All of our air filters are manufactured in the USA, so you don’t have to worry about quality. These air filters use high-quality material to provide superior indoor air quality for a long time.

Constructed with an electrostatically charged material, these HVAC filters come with a high dust holding capacity. In addition, these filters help improve the efficiency of your HVAC system by capturing almost all of the dirt and dust particles and reducing the load on the motor.

Though our 20x23x1 air filters are long-lasting, Custom Filters Direct recommends you to check them regularly and replace them every 2-3 months.
