The Koch Disposable Polyester Panel filter in 22 22 1 is a budget-friendly panel filter built for equipment protection and high airflow. Polyester media is tougher and more durable than spun fiberglass it holds its shape better in high-airflow installations and doesn’t shed fibers into the airstream.
Equipment protection first, filtration second
Like other MERV 14 panel filters, Koch disposable polyester is designed to protect the coil and blower from lint, hair, and large debris not to filter fine dust or allergens. For allergen-level filtration, step up to a pleated MERV 8 or higher.
Understanding the MERV 14 rating
Fiberglass media is rated MERV 1 when clean and builds up to MERV 4 as dust loads onto the fibers. That’s not inconsistency it’s how spun-glass media works. A fresh filter lets the most air through while still blocking larger debris; as dust collects, the media becomes more efficient at catching finer particles. The goal of a MERV 14 filter isn’t air quality it’s equipment protection with maximum airflow. It keeps lint, hair, and large dust out of your coil and blower, which is exactly what older systems, high-airflow applications, and pre-filter duty need.
