HEPA Filter Testing

HEPA Filter Testing

High Efficiency Particulate Air filters (HEPA Filters) are devices which remove solid particles such as pollen, dust and bacteria from the air.  HEPA Filters are used to remove ultrafine dust, aerosols and viable organisms. High Efficiency Particulate Air filters are most commonly found within operating theatres and patient isolation rooms within hospitals, cleanrooms and laboratories but also for micro-electronics, optical and pharmaceutical production.

Why HEPA Filters are Installed in Cleanrooms

Good quality Filters are necessary in a cleanroom to remove various different types of contaminant from the air and ensure the right level of air purity is maintained consistently. Filtration provides protection for people working in the confined space, as well as for production and the surrounding environment.


The choice of a ventilation system for a cleanroom is a major decision and must be carefully considered. In many instances design advice from experts will be required to highlight which equipment is most appropriate. As well as the design and layout of the area, other key points to bear in mind include the type of application and the direction of airflow which is needed.

A critical ventilation system must have the right filters installed within it. High efficiency particulate air (HEPA) filters have to meet official standards including the British and European standard BS EN 1822-1: 2009. This means that, in factory testing, these filters must have an efficiency level of more than 99.995%.

A high quality HEPA filter will remove particles of solid contaminants including dust, mould, and bacteria room the air. It can screen tiny particles above 0.3 micrometres in size. There are various different types of HEPA filter available and they are frequently used in cleanroom settings within pharmaceutical and electronics production, as well as in hospitals and healthcare facilities.
