Product Introduction
The metal frame of the Strengthen Pleated Pre-Filter Of Metal Frame is made of galvanized steel wire, aluminum alloy, or stainless steel. The frame features an interwoven grid structure that forms a stable and robust support system.
The filter media are typically made of polyester fiber, non-woven fabric, nylon mesh, or activated carbon. With a density-gradient structure from coarse to fine, the filter effectively captures large airborne particles such as hair, skin flakes, and fibers.
