Know how your Air Purifier works
The air purifier functions as an air cleaner by helping to disinfect airborne bacteria and removing particles
from the air.
The air is cleaned in three stages:
1. A fan draws air through the intake grille on the rear of the air purifier. Then it passes through the pre-
filter which traps large dust particles.
2. The white HEPA filter then removes particles as small as 0.3 microns from the air at 99.97%
effectiveness.
3. The clean air is then exposed to germicidal-grade ultraviolet light to reduce the level of airborne
bacteria, moulds, and viruses. The purified air is then released through the outlet grille on the top of the
unit.
