HEPA Filtration: Validation, Testing and Changing: eLearning

This 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.

It is an online eLearning course studied in your own time, followed by a multiple-choice assessment, leading to a certificate of completion. The eLearning course is designed to provide an understanding of HEPA filters, from background material, to testing and handling, and onward to changing and disposal; both the volumetric and face-scanning methods are included, according to Standard EN 1822-1 & BS EN ISO 14644-3:2019. This module is prepared in English (UK) and success will be recognised with a certificate of completion. 

Please note that this module does not include any hands-on practical training. For those wanting practical experience of testing using the volumetric method, we do offer a 1 day instructor-led course (ILC) held at our Surrey site in the UK.
