The pre filter is designed as a barrier, to capture the larger dust and particulate, protecting the HEPA filter from premature blocking.
BOFA offers a range of pre filters, all designed for different applications and processes, depending on the amount of dust being extracted.
The efficiency of the pre filter is directly related to the life of the HEPA in that the more particulates captured in it, the less can pass through and prematurely block the HEPA. Most pre filters have an efficiency grading of F5 - F7.
