Custom Filters Direct is the name you can count on when looking to buy the best quality 18x36x1A air filters online. Our electrically charged air filters ensure dirt, dust, and other irritants are removed from the air before it enters your home or business environment.
All our air filters are made in our own factory in the USA, helping our customers get the best quality products at pocket-friendly prices. We strictly follow the HVAC industry standards and use the finest quality material to ensure air filters withstand harsh conditions.
Custom Filters Direct 18x36x1A furnace and AC air filters are constructed using the highest-quality synthetic material which makes our air filters almost 20 times more efficient in trapping harmful contaminants than ordinary filters. The tight mesh weaving ensures the airflow is clean and free of harmful particles.
Over time, the dirt and dust particles accumulate on the surface of the air filter and block the pores of the filters. When this happens, the flow of clean air is reduced and puts a strain on the HVAC unit. It may cause high energy bills and costly repairs.
For optimal performance, we recommend you to change your filters every 60-90 days. You can replace your filters every 30 days during the peak seasons or if you have pets at home.
