Whatever the season in the USA, allergens are everywhere year-round. These allergens can cause allergies or severe breathing problems. This is why effective air filtration in your home’s HVAC system is so important!

The primary purpose of Custom Filters Direct 20x30x1 air filters is to capture and trap most solid contaminants, such as allergens, pet dander, dust, smog, and even mold spores. Our HVAC air filters can help remove particulates from the air before they reach your lungs, so you’re better protected against inhaling allergens.

Our 20x30x1 air filters come with a charged synthetic media which has better dust holding capacity than any ordinary air filters available on the market. Capable of removing more than 90% of the particles, these filters will help you enjoy clean, healthy air all year around.

Custom Filters Direct 20x30x1 air filters capture small airborne particles as they pass through your home’s HVAC system. As a result, the pores on the filter get clogged with dirt and don’t let the clean air pass through. We recommend you replace your filter every 2-3 months to maintain indoor air quality.
