Buy 18x18x1A Air Filters Online

Whether it’s your home or office, indoor air pollution can cause severe health issues to the people living or working in the area. The airborne particles floating in the air can cause serious health issues to those who have asthma or allergies.

Custom Filters Direct 18x18x1A air filters are specifically constructed to promote indoor air
quality while reducing harmful pollutants in the air. These filters not only eliminate more than 90% of the dust particles but also remove odor-carrying particles and gasses.

Manufactured in the USA with HVAC industry standards in mind, our 18x18x1A AC and furnace air filters are an economical way to improve the indoor air quality of your residential, commercial and industrial space. The strong frame used in these filters holds the pleats and maintains the shape during high pressure.

The unique design and tight mesh weaving hold the dust particles while allowing the clean, fresh air to pass through. Over time, the filters become dirty and lose their potential to capture the particles. So it is essential that you change your air filter every 2 to 3 months.

Select the Right MERV Air Filter

MERV 8

Our MERV-8 air filters are a cost-effective way to eliminate most unwanted airborne particles like pollen, dust, dust mites, and more ranging from 3 to 10 microns in size.

MERV 11

These air filters are more efficient at capturing particles than MERV 8 filters. These air filters will capture more than 85% of troublesome particles 3.0-10.0 microns in size and 50% of the particles 1.0-3.0 microns in size.

MERV 13

MERV 13 filters are an ideal choice when you need superior air quality. These AC and furnace filters capture more than 90% of the particles 3.0-10.0 microns in size and 75% of the particles 0.3-1.0 microns in size.
