HEPA Filtration: Validation, Testing and Changing

This 1-day practical course is designed primarily for maintenance technicians and those wanting an introduction to the principles of testing, validating and changing HEPA filters that are installed in air handling systems, forming part of a biocontainment barrier. 

The course will provide delegates with the theory found in our online eLearning course, covering both the volumetric and face-scanning methods, according to Standard EN 1822-1 & BS EN ISO 14644-3:2019 complementing this with the practical experience of setting up, carrying out and recording a volumetric test on our purpose-built test HEPA filter housing.  

What you need to know
