Shop 20x34x1 Air Filters Online

Air filters perform a crucial job in your home’s HVAC system, especially during the peak season. They trap and capture airborne pollutants, allowing you to enjoy a clean and healthy environment.

Custom Filters Direct offers premium quality 20x34x1 air filters, designed to capture small and large-sized particles while allowing the clean air to pass through. These filters block animal fur, mold spores, bacteria, pollen, dust, dirt, and more.

These filters provide excellent clean airflow and eliminate almost all of the harmful allergens present in the indoor air. This will help reduce the risk of getting sick from exposure to harmful bacteria.

Our HVAC air filters come with a heavy-duty board frame that stands up to rough and difficult conditions while providing long-lasting results. Their tight mesh weaving captures even the smaller size particles while allowing the clean, healthy air to flow inside your home.

Though our high-quality air filters 20x34x1 are long-lasting, they typically require replacement once every three months. If you have pets at home or are prone to allergies, you should replace the air filters more frequently, such as once a month.

Select the Right MERV Rating


These AC and furnace filters are designed to improve the indoor air quality of the most common household settings. MERV 8 filters collect 85% of particles 3.0-10.0 microns in size.


MERV 11 air filters have higher efficiency in eliminating harmful particles and odor-carrying particles and gasses. These air filters are the perfect solution for those who have pets or have moderate breathing issues.


If you or your family members suffer from severe breathing issues or have pets in the home, then choose MERV 13 AC and furnace air filters. These filters eliminate more than 90% of harmful allergens between 3.0 to 10.0 microns and 75% of particles down to 0.3 to 1 microns in size.
