HEPA filter is a very common product for cleanroom, for residential and for industrial applications, it can remove dust size over 0.3 microns with good efficiency. Most of the HEPA filters are made of glass fiber media, metal or plastic or wooden frame, sealed by glue and gasket. It should be replaced every 2-3 years if it`s for industrial and cleanroom application. All HEPA filter should be tested before they leave factory and should be tested before its application. At the present, there are two most common design HEPA filter, laminar flow mini pleated HEPA filter and separator HEPA filter.
