Although they’re a crucial component for almost any industrial vacuum cleaner, many people are still unsure exactly what a HEPA filter really is, what it does, and how the effectiveness of a HEPA filter is measured and certified. In this blog post, Proquip’s vacuum experts will take you through the answers to these common questions, and let you know which of the industrial vacuums available from Proquip is right for you!

What is a HEPA filter?

HEPA stands for “high-efficiency particulate air”. Simply put, a HEPA filter when installed in a vacuum will be able to capture a large number of tiny particles – such as dust – that would otherwise be recirculated directly back into the air. Vacuums with a HEPA filter are a much better choice for people with allergies and respiratory issues who might be negatively affected by dust and other allergens.

How are HEPA filters tested and certified?

HEPA filters normally have to be tested to certify their ability to trap 99.97 per cent of particles at a size of 0.3 microns, which is the minimum size of most household particles. Filters that pass the test are certified as “true HEPA filters” and are normally more expensive than those that don’t reach this level – of which there are many.
