Primary Air Filter
The primary air filter serves as the first line of defense in an air filtration system, primarily designed to filter large particles such as dust, hair, and fibers larger than 5 microns. Its key role is to protect downstream medium or high-efficiency filters, thereby extending the overall lifespan of the equipment.
The primary filter screen works in tandem with HEPA filters: the former captures large particles, while the latter filters fine particles as small as 0.3 microns (e.g., PM2.5, pollen). Most air purifiers use a multi-layer filter combination of "primary + HEPA + activated carbon" for comprehensive air purification.
