Cleanroom filtration refers to the process of removing contaminants from the air within a cleanroom environment to maintain a controlled and sterile environment. Cleanrooms are typically used in industries such as pharmaceuticals, electronics manufacturing, and biotechnology, where even small particles and contaminants can have a significant impact on the quality of the products being produced.
Cleanroom filtration typically involves the use of high-efficiency particulate air (HEPA) filters or ultra-low particulate air (ULPA) filters to capture and remove airborne particles and contaminants. HEPA and ULPA filters are designed to capture particles as small as 0.3 microns and 0.12 microns, respectively.
Cleanroom filtration systems typically consist of a combination of pre-filters, which capture larger particles and contaminants, and HEPA or ULPA filters, which capture smaller particles and contaminants. Air is typically drawn into the cleanroom through the filters and then recirculated through the room.
