Fiberglass HVAC Panel Filters, 20x20x1, 12-Pack for Airflow-Focused Equipment Protection, MERV 1-4
Fiberglass HVAC filters help keep lint, hair and large dust out of coils and blowers while prioritizing airflow. This 12-pack of 20x20x1 Flanders EZ Flow panel filters provides replacements for routine equipment maintenance.
The spun-fiberglass media is intended for equipment protection in airflow-focused applications, including suitable older HVAC systems and pre-filter installations. It is rated MERV 1 when clean and builds toward MERV 4 as dust collects. These filters are not designed to capture fine dust, allergens or smoke.
Features
- Continuous-filament spun fiberglass bonded with resinous adhesive provides rigidity and compression resistance.
- One-piece heavy chipboard frame eliminates corner seams that can separate.
- Media is attached directly to the frame with hot-melt adhesive, without a metal retainer.
- Captures larger debris before it reaches HVAC coils and blowers.
- A case of 12 filters supports recurring replacement needs.

Frequently Asked Questions
What size and quantity does this filter pack contain?
This pack contains 12 fiberglass panel filters in the 20x20x1 size. Match that size to your equipment's required filter size before ordering.
Are these filters suitable for allergen or smoke filtration?
These fiberglass filters are designed for equipment protection rather than allergen or smoke filtration. They catch larger debris such as lint, hair and large dust clumps.
Why does the MERV rating range from 1 to 4?
The fiberglass media starts at MERV 1 when clean and builds toward MERV 4 as dust collects on the fibers. Its primary purpose remains equipment protection while prioritizing airflow.
How often should these HVAC filters be replaced?
Replace these HVAC filters every 30 days under typical use. Follow your equipment's maintenance requirements when planning replacement.
Can these panel filters be used as pre-filters?
These panel filters can serve as pre-filters ahead of a higher-MERV filter in a suitable installation. Their role is to intercept larger debris before it reaches the next filtration stage.
