View →How the filtration works
- 1
Air intake
Outside air is drawn through a blast valve, which protects the intake from the effect of a shock wave.
- 2
Pre-filtration
The main pre-filter and an F7 class filter capture dust and the coarser particles in the air.
- 3
HEPA and carbon filter
The H14 class HEPA filter captures finer particles, including bacteria and viruses. The carbon filter absorbs toxic gases and volatile compounds.
- 4
Positive pressure
A positive pressure is held in the room through an overpressure valve, so unfiltered air cannot enter through gaps.
