Xiaomi SmartMi Air Purifier Filter ZMFL-P1-A For Air Purifier P1 Pollen Allergy

The H13 True HEPA filter effectively removes unwanted airborne particles in the home with four different filtration levels. The H13 True HEPA filtration process consists of a pre-filter, NanoGuard filter, activated carbon filter, and an internal filter. The filter's lifespan is approximately 6 to 12 months, depending on usage and exposure to polluted air.

The H13 True HEPA features a four-stage structure:

1. Pre-filter: Retains larger airborne particles such as dust, pollen, and mites.
2. NanoGuard filter: Purifies the air of particles as small as 0.1 μm with an efficiency of 99.99%. It also cleans the air of airborne particles such as dust, pollen, bacteria, mold, and other harmful substances.
3. Activated carbon layer: Neutralizes the air of volatile organic compounds (TVOC), including invisible smoke odors, viruses, and formaldehyde, which can cause serious health effects.
4. Internal filter: Removes residual particles that have not been filtered out in the previous processes.
