An efficient filtration
The basis of a quality air purifier is its filtration system. Your air purifier must be equipped with three levels of filter:
- A pre-filter to retain big particles, hairs, pet dander to protect the rest of the filters from a too fast clogging,
- A HEPA filter (High Efficiency Particulate Air) that will capture airborne fines particles,
- an activated carbon filter that will retain gaz, volatile organic compound and odors.
Moreover, the surface of these filters will determine the efficiency of the filtration. More the surface area is important, the more efficient the filtration is.
