High Efficiency Particulate Air (HEPA) filters that are true to the standard are capable of trapping and removing airborne particulates as small as 0.3 microns. That’s smaller than the human eye can physically see. True HEPA filters are known by the fact that they’re able to capture 99.97% of all particles. Even the most dangerous particles can be stopped in their tracks due to how their designed to perform.
Fibers are the bread and butter in capturing and trapping dust particles. There are three stages that HEPA filter fibers can stop particles in their tracks.
Stage 1 – Impact: Most of the dust particles that are sucked into a HEPA filter crash into filter fibers and are trapped by impact. Fibers are capable of holding dust particles completely, resulting in very little particles making their way through.
Stage 2 – Interception: As dust particles move throughout a HEPA filter, the airstream caused by the vacuum enables particles to get too close to a nearby fiber, stopping them in their tracks. This is referred to as interception.
Stage 3 – Diffusion: In vacuums that output lower speed airstreams, dust and air particles can crash into one another. This results in being redirected to nearby filter fibers. This is referred to as diffusion.
Because HEPA filters are designed to capture dust particles in multiple ways, this eliminates the risk of particles making their way out – resulting in 99.97% being captured. With an industrial HEPA vacuum built to perform at that level, your workers will be protected from silica dust, beryllium and whatever other airborne dust particles may be present at your job site.
