3-layer combined filter:
- Primary filter - captures large particles that float in the air, while keeping the HEPA filter from loading quickly.
- Cell Activated Carbon Filter - This filter contains highly active additives. There is the possibility of good absorption and retention of dust particles.
- High performance HEPA filter - The accuracy of this filter is reduced to 0.01 microns and can capture and retain particles larger than 0.01 microns with an efficiency of 99% or greater. Dust, bacteria, mold, viruses, allergens, etc. small particles cannot pass through the HEPA filter.
