Description
This 20″ × 30′ × 1″ Hog Hair service roll is a natural-fiber commercial filter media, used as bulk roll stock for cut-to-fit commercial and industrial filtration. The fiber structure is rigid enough that it requires no frame support — cut to size, slide into your housing, and you’re installed.
Why natural-fiber media
Hog Hair has a three-dimensional fiber structure that captures dust and lint throughout the full depth of the media rather than just on the surface — higher dust-holding capacity than flat-panel filters and longer service life.
Understanding the MERV 1–4 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 1–4 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.
Typical applications
- Commercial air handlers with custom filter housings
- Paint-booth and spray-booth pre-filtration
- Industrial dust-collection pre-filtration
- Replacement for any standard furnace filter size (cut to size)
Specifications
- Media: 100% natural organic fiber — no resin required, structurally rigid
- Rating: Up to MERV 4 (efficiency builds as the filter loads)
- Format: Bulk roll — cuts cleanly with shop scissors or utility knife
