3. Operating Principles (Filter Function)
The KNKA APH3000 replacement filter employs a multi-stage filtration system to ensure comprehensive air purification:
- True HEPA Filter: This layer is designed to capture at least 99.97% of airborne particles as small as 0.3 microns. This includes common allergens like pollen, pet dander, dust mites, and mold spores.
- Honeycomb Activated Carbon Particles: The activated carbon layer is highly effective at adsorbing various odors and harmful gases. It neutralizes smells from pets, cooking, smoke, and volatile organic compounds (VOCs), contributing to a fresher indoor environment.
