Custom Filters Direct 13x18x1A air filters are capable to eliminate tough pollutants and giving you excellent indoor air quality. These air filters are easy to install in almost any air conditioner unit and work as a protection layer against allergens and irritants.

Our 13x18x1A air filters are pleated high-capacity filters constructed with 100% synthetic material. This material offers significantly higher particulate efficiency and captures even the smallest and most troublesome airborne particles.

Using our air filter is the best way to eliminate more than 90% of the harmful particles like pollen, mold, bacteria, viruses, smog, pet dander, and more. However, we recommend you inspect your air filters regularly, and replace them every 90 days.

These high-quality air filters are available in several different MERV ratings to provide you with the best filtration levels to meet your needs. We have 13x18x1A air filters available in MERV 8, MERV 11, and MERV 13 options for your specific residential or commercial needs.

MERV 8, MERV 11, MERV 13 Air Filters


MERV 8 air filters are a good option for standard residential clients as these filters capture up to 85% of particles between the sizes of 3.0 – 10 microns.


The MERV 11 filters are better at capturing pet dander and bacteria from sneezes than MERV 8 filters. These AC and furnace air filters also provide additional protection against smoke, smog, and automobile exhaust fumes by capturing more than 85% of particles ranging between 3.0 – 10.0 microns and 50% of particles between 1.0 – 3.0 microns.
