| Factor | Pleated | Fiberglass |
|---|---|---|
| Particle capture | Typically higher | Basic |
| Surface area | More, due to folds | Less |
| Typical use | Household air quality and equipment protection | Basic equipment protection |
Why pleats matter
Pleats create more filtering surface within the same frame size. That can improve capacity and particle capture.
When fiberglass may make sense
A basic fiberglass filter may be suitable when the system requires very low resistance and the goal is mainly protecting equipment from large debris.
Use the printed rating
Material alone does not tell the whole story. Compare the MERV rating, dimensions, and manufacturer guidance.
