Indoor air pollution can be even more harmful than outdoor air pollution. Superior quality air filters are required to add a layer of protection for everyone to enjoy clean, healthy indoor air.

With the help of the Custom Filters Direct 18x30x1 air filters, you can easily maintain indoor air quality while keeping most bacteria and irritants out of your home or business environment. These air filters are the perfect fit for any home or office HVAC system, eliminating more than 90% of the unhygienic particles coming with the airflow.

Custom Filters Direct 18x30x1 air filters also prevent the build-up of harmful airborne particles on your duct that can affect the performance of the unit.

All of our AC and furnace air filters are manufactured in the USA with the highest quality materials, making them an affordable choice for residential, commercial, and industrial areas. Our air filters feature a tight mesh weaving to capture even smaller particles that ordinary filters won’t.

Though our air filters are designed to promote clean airflow, dirt may start building up on the surface of filters after a few months. Using dirty air filters will not allow the clean air to pass through, and will also put a strain on the HVAC motor. So, we recommend you change your air filters every 60-90 days.

MERV 13

MERV 13 air 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, making them an ideal choice for commercial and industrial applications.
