When it comes to performance, our air filters are second to none at blocking harmful sinus, irritation, and allergies coming with the outdoor air.

The unique design of these AC and furnace air filters makes them 30 times more efficient and last longer than any other air filters available on the market. Using our 8×35.5×1 air filters ensures you not only get rid of indoor air pollution but also get rid of odors that are not pleasant to your nose.

When used for a long time, the dust gets accumulated on the surface of filters. The dirty particles accumulated block the filter’s pores over time. Custom Filters Direct recommends you to replace your air filters every 60-90 days.
