What is the best air filter for my home?

The best air filter depends on size or dimensions, filtration rating (MERV, MPR, FPR), and quality your AC unit requires. Our filters capture up to 98% of microscopic airborne particles (3-10 um) with industry leading low pressure drop.

How do I replace my air filter?

Confirm the size of your air filter. Remove plastic wrapping on your new filter and locate the arrows to indicate the direction of air flow. Open your air vent cover, insert the new filter with the arrows facing correctly, then shut air vent cover.

What does MERV mean in air filters?

MERV stands for Minimum Efficiency Reporting Values which reports a filter's ability to capture microscopic particles ranging from 0.3 and 10 microns (µm). The higher the MERV level, the more efficient it is at filtering microscopic particles.

What is the difference between Nominal Size and Actual Size of Air Filters?

The nominal size is a rounded number to the nearest whole or half inch, (ex: 20 x 20 x 1). The Actual Size is the exact measurement that shows the filter's actual dimensions (ex: 19.75 x 19.75 x .75). All Air Filters display both sizes.

What quantity of air filters should I buy?

This is dependent on each customers unique air filter requirements. Our selection includes pack sizes that range from 1 to 12 filters. Each filter last up to 3 months depending on various aerosol conditions such as, dust, smoke, and pets.
