Custom Filters Direct 12x20x1 air filters provide exceptional air filtration solutions for both residential and commercial environments. Each time air passes through a 12x20x1 HVAC air filter, more than 90% of allergens and dust particles, as small as 0.3 microns, are eliminated from the airflow.
Our air filters are 100% manufactured in the USA using moisture-resistant beverage board frames to attract unwanted nuisances that flow in the air stream. In addition, these filters will prevent the growth of bacteria or mold and are better at trapping airborne particles than ordinary filters.
The synthetic filtration media used in our 12x20x1 air filters has unmatchable particle capture rates. They are highly efficient at removing humid air while ensuring the best overall performance of your HVAC system.
The effective life of your furnace and HVAC filters depends on both the inside and outside environment in which you live. It is important to frequently change your HVAC filters, especially during the peak of summer and winter. Custom Filters Direct recommends you change your air filter every 2-3 months to maintain the highest efficiency of the HVAC system.
MERV 8 furnace and HVAC air filters are the most commonly used for residential purposes. These air filters would be great for a family that doesn’t smoke, doesn’t have pets, and doesn’t have bad allergies. These filters will capture up to 85% of particles between 3.0 – 10.0 microns in size.
People with pets or allergies will take benefit from MERV 11. A MERV 11 filter eliminates pet dander, dust, pollen, and other particles that are present in the air. These air filters will capture more than 85% of particles 3.0-10.0 microns in size and 50% of air particles down to 0.3 microns in size.
A MERV 13 air filter is great for people with severe allergies and who own multiple pets. These filters will capture even smaller dust particles between 0.3 to 10.0 microns in size including dirt, pollen, mold spores, pet dander, and more from your home’s air.
