Environmental cleanliness in enclosed spaces. Guide to in situ high efficiency filter leak testing not-for-sale Short circuit and overload protectionWhere high efficiency filters are fitted, it is important to ensure that the filter and its housing and sealing device do not permit the ingress of particles into a cleanroom or clean zone. This is checked by challenging the filter with an aerosol of particles dispersed upstream of the filter and scanning over the downstream face, frame and gasket of the filter to ensure that there are no leaks that exceed a specified level of penetration.
