Description
The Koch Disposable Fiberglass Panel in 10″ × 10″ × 2″ is a straightforward spun-fiberglass panel filter — the baseline category for HVAC equipment protection. It’s built to catch lint, hair, and large debris while letting the system breathe.
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.
Construction
- Media: Continuous-filament spun fiberglass with resinous bonding agent for rigidity.
- Frame: One-piece heavy chipboard, moisture-resistant.
- Service life: 30 days under typical use.
When fiberglass makes sense
- Rental properties and budget-conscious residential applications
- Legacy HVAC systems not rated for higher-MERV pressure drop
- Commercial pre-filter duty ahead of a higher-MERV final filter
- High-airflow applications where pressure drop is critical
