HEPA Filter? What’s a HEPA filter?


And who needs one?

Well, to begin with, there’s more – much more – to a HEPA filter than first meets the eye. But first things first. What is a HEPA filter? And what does HEPA stand for?
HEPA stands for High Efficiency Particulate Air. When used to describe the quality of a filter, or a dust mask for example, the term HEPA also stands for High Efficiency Particulate Arrestor.

To us HEPA is not just an acronym, it’s a promise. A promise which we take very seriously.

HEPA filters are highly efficient air filters designed to hold back airborne pathogens. And being Filter Class H13 and H14 filters that means that they are able to retain a remarkable 99.97% of all airborne particles greater in diameter than 0.3 microns (the cross-section of a human hair is over 200x the size!).

When we refer to airborne matter, we are not just talking about any old airborne matter. We are talking about viruses, inhalable dusts, mites, pollen, grass pollen and smoke particles. These are particles which can have a serious effect on your health and negatively affect your feeling of well-being. HEPA filters can even filter asbestos fibres, bacteria and a variety of toxic dusts and aerosols. It therefore goes without saying that this does not only make HEPA filters ideal for people who suffer from allergies. It makes them ideal for everyone.

Which is why HEPA filters are often used in nurseries, residential homes and medical areas where they already protect those who are often more susceptible to illnesses and diseases which can arise from breathing in the airborne pathogens described above.

It is important to know that the filters are divided into filter classes which depend on the purpose for which the filter was designed. And although these classes must comply with the EN ISO 14644, a euro norm designed to subdivide rooms into individual clean room classes, they are not adhered to by all manufacturers. Some manufacturers of vacuum cleaners, for example, like to adorn their products with this special distinction despite the fact that the filters they are keen to promote do not perform the task you think they would. This is because the systems in question are not sealed systems, ie. there is no guarantee that the air actually passes through the filters.

Which is where we come to the promise we made earlier. Because this is a promise that is too important to be taken lightly. The HEPA filters that are used in the machines and appliances from Trotec do exactly what they are supposed to do.

At TROTEC you will find a broad selection of HEPA filters and they all fulfil the stringent EN norms.

  • In water damage restoration:
    Trotec provides HEPA filters for water damage restoration, eg. in nurseries, hospitals and care homes. This means that pollen, viruses and other particles are filtered out of the layers below the surface before they can enter the surrounding air. The appliances even have a HepaControl status display which shows you when the HEPA filter has to be replaced so that you can continue to rely on us.
  • To clean air:
    All the air filters from Trotec are equipped with special filter combinations which make them ideal for filtering allergens, bacteria and mould spores out of the ambient air. Trotec also has a range of robust air cleaning systems in the TAC series for use on building sites and in sanitary areas as well as a variety of sophisticated yet easy-to-use IQAir models designed especially for use at home, in offices and workshops and clinic rooms.

Not only do we pride ourselves on being specialists, we also pride ourselves on being able to offer you a wide selection of high-quality, highly efficient air cleaners that do exactly what they are supposed to do.

Perhaps it’s time we shook up the market and turned our hand to vacuum cleaners.

Trotec. Because good just isn’t good enough.
