Whole-Home Air Filtration

The A-Series replaces the thin, one-inch filter in your HVAC with a deep, four-to-five-inch media cabinet at the return. With far more surface area, it actually catches the fine particles the cheap filter lets sail through — dust, pollen, pet dander, and smoke.

Because it's built into the system you already own, it cleans the air of the whole house every time the heat or AC runs — not one corner like a portable unit. You'll notice less dust on every surface and real relief if anyone in the house has allergies.

We match the filter to your specific blower so it cleans hard without over-restricting airflow. It's an Aprilaire system, and the replacement media ships to you through Cardinal Care.
