3-in-1 Filtration System
The filter system employs a three-stage purification process:
- Pre-filter: Captures larger particles such as hair, lint, and pet dander. This stage helps extend the life of the subsequent filters.
- H13 True HEPA Filter: Designed to capture 99.97% of airborne particles as small as 0.3 microns, including pollen, dust mites, and smoke particles.
- Activated Carbon Filter: Absorbs unpleasant odors from pets, cooking, and smoke, as well as harmful gases.
