Leak test of a high-efficiency filter

High-efficiency particulate air (HEPA) filter leak testing generally involves applying challenge particles upstream of the HEPA filter and then using a particle detection instrument to scan the filter surface and frame for leaks. Several different methods of leak testing exist, each suitable for different applications.
