There are just as many air pollutants inside your home as outside. These indoor air pollutants cause havoc on your health, home, furnace, and air conditioner system when you don’t use high-quality air filters.

Custom Filters Direct represents the premium 20x22x1A air filters that provide the best air filtration solutions for both homes as well as commercial environments. These air filters are made with electrostatically charged synthetic media. When the air passes through this media, more than 90% of the harmful allergens are filtered out and help you keep the indoor environment comfortable and healthy.

Unlike other air filters, Custom Filters Direct 20x22x1A filters are manufactured in our own factory in the USA with HVAC-industry standards in mind.

These air filters block and restrict a massive amount of allergens while providing superior indoor air quality for a long time.

Custom Filters Direct 20x22x1A air filters keep your entire unit clean, preventing dust and debris from settling on the HVAC motor.
