Providing Clean Air
HEPA filters have been with us for many years now, and they are great. You’ll find them in medical applications, HVAC systems and even in popular vacuum cleaners. In fact Miele were using HEPA filters in their vacuum cleaners back in the 90s and it was deemed to be a good thing, even then.
But what is an HEPA Air Filter?
HEPA stands for High Efficiency Particulate Air. HEPA filters are a type of filter made from finely interlaced fibres of polypropylene or fibreglass with the fibres having a diameter of less than 2 micrometers.These fibres are woven together and then pleated or used in multiple sheets.
To be classed as HEPA a filter has to remove at least 99.97% of dust, pollen, mould, bacteria, and any airborne particles with a size of 0.3 microns (µm).
You’ll find HEPA filters in a wide range of devices and they are designed to remove a wide range of particles and pollutants from the air in your office, medical facility, home and other buildings.
