If we’re speaking HEPA, we’re speaking about particles which have been so small you'll be able to’t see them. A HEPA filter eliminates these through the air by building them keep on with a fiber. This happens via diffusion, interception, inertial impaction, and electrostatic attraction.

When adhering to the ISO or European principles, filters that seize ≥eighty five% of particles but under 99.ninety five% are known as ‘EPA filters’ or ‘efficient particulate air filters’. These air filters usually do not satisfy the filtration prerequisite to be regarded a ‘HEPA air filter’.
