Why should you always use a vacuum with a HEPA filter? 21 Mar, 2018

Why should you always use a vacuum with a HEPA filter?

HEPA stands for ‘High Efficiency Particulate Air’ and when buying a vacuum cleaner, having a HEPA filter should be seen as essential. HEPA filters trap extremely small particles that other vacuums would recirculate back into the air. Trapping these particles can help in managing allergies, and is ideal for facilities where hygiene is an important factor with floorcare.

A HEPA filter consists of a random arrangement of fine fibres rather than a regular weave, and traps the particles though a mixture of direct impaction and interception / electrostatic attraction. The overall process is complex, with different mechanisms predominating at different airflow rates.

In order to be called a HEPA filter, it has to be tested and approved against an appropriate standard (e.g. EN 1822:2009 pertains in the UK and Europe). Filters are graded according to the proportion of microscopic (down to 0.3 micron) particles that they trap, with H13 grade trapping up to 99.97%. The tests also ensure that the pressure drop due to the filter is acceptably low.

To give an idea of the particle size, a human hair is typically 70 microns (μm) in diameter. Pollens are over 10μm, and so will be filtered out effectively, as will fungal and mould spores (2μm+).

Checking for true HEPA filtration is a great way to ensure you’re purchasing a quality vacuum that provides first-rate cleaning results.

The VTVe is a compact tub vacuum that’s inclusive of a HEPA filter. Featuring an A energy rating, this vacuum cleaner provides outstanding cleaning results and:

Other products

The VBPIIe also feature HEPA 13 Filters, as part of a multi-stage filtration process (just as with the VTVe). This gives the HEPA filter a very long life, as it is only removing microscopic particles from air that has already had the larger particles filtered out.
