The H13 True HEPA filter effectively removes unwanted airborne particles in the home through four different filtration stages. The H13 True HEPA filter process is based on four phases: a pre-filter, a NanoGuard filter, an activated carbon filter, and an inner filter. The filter's lifespan is approximately 6-12 months, depending on how often the air purifier is used and how much unhealthy air it has been exposed to.

Pre-filtration of particles
The pre-filter captures larger airborne particles such as dust, pollen, and mites.

NanoGuard filtration
The second filtration process consists of the NanoGuard filter, which cleans the air of particles as small as 0.1 μm, achieving an efficiency of 99.99%. NanoGuard also removes airborne particles like dust, pollen, bacteria, mold, and other harmful substances from the air.

Activated carbon layer
The third filtration stage consists of the activated carbon layer, which neutralizes volatile organic compounds in the air. The carbon filter neutralizes invisible smoke odors, viruses, and formaldehyde in the air, which can pose several serious health risks.

Final filtration
Finally, the final filtration consists of the inner filter, which removes remaining particles that were not eliminated in the above processes.
