Custom Filters Direct 14x18x1 air filters are ergonomically designed to provide exceptional filtration at reasonable prices. 100% made in the USA, our air filters are designed to filter more than 90% of the harmful particles in the air stream. If you or your family members suffer from allergies or have respiratory problems, our air filters are an ideal solution to easily maintain clear, healthy indoor air quality.
Our 14x18x1 air filters are specifically engineered for residential, commercial, and industrial furnaces and air conditioners. Made with 100% synthetic material, these AC and furnace air filters are almost 20 times more efficient in trapping harmful contaminants than ordinary filters. These air filters make the HVAC unit work more efficiently while providing the very best air quality and environmental conditions possible. Moreover, our air filters put less strain on HVAC unites when drawing in air and keeping large & small particles away from your space.
Ideal for standard residential settings, MERV 8 air filters are highly efficient at eliminating 85% of the particles from the air. These air filers will help you eliminating Pollen, Dust Mites, Bacteria, and more.
MERV 11 filters are effective at trapping more than 85% of airborne particles 3.0-10.0 microns in size and will also capture 50% of allergens 1 to 3 microns in size. The air filters are a good option for households with pets or those looking for even better air quality than the MERV 8 can provide.
These air filters have the highest capacity to immediately grab and trap microscopic airborne contaminants including smoke, bacteria, viruses, and more. Our MERV 13 filters will capture more than 90% of particles between 3.0-10.0 microns in size and 75% of particles between 0.3-1.0 microns. These are great choices for hospitals, surgical unites, and universities, or wherever higher efficiency filtration is needed.
The air filters in your HVAC need to be changed regularly. Over time, pollutants begin to accumulate on the surface of the filters, resulting in a lack of clean airflow through the filters. Therefore, it is necessary to change the filters every 60-90 days to maintain proper air filtration.
