3. How the Filter Works (Filtration Process)
The CONOPU JH04 replacement filter employs a comprehensive 3-layer filtration system to purify the air:
- Pre-filter: This initial layer captures larger airborne particles such as dust, lint, pet hair, and fibers. This extends the life of the subsequent filters.

- H13 True HEPA Filter: The core of the filtration system, the H13 True HEPA layer is highly effective at capturing 99.97% of airborne particles as small as 0.3 microns. This includes pollen, pet dander, mold spores, and dust mites.
