The build-up is necessary to avoid the need to replace the absolute filter quickly. An absolute filter is commonly referred to as a HEPA or ULPA filter.<\/p>\n<div><span>HEPA (high efficiency particulate air):<\/span><\/div>\n<div>Stops particles 0.3 \u00b5m in diameter with an efficacy of 99.97%.<\/div>\n<div><span>ULPA (ultra-low penetration air):<\/span><\/div>\n<div>Stops at least 0.1 \u00b5m diameter particles with an effectiveness of 99.999%.<\/div>\n<p>There are several methods for bringing air into the cleanroom, including:<\/p>\n<ul>\n<li>Via Filter boxes in the ceiling grid of various kinds<\/li>\n<li>Via air-sockets<\/li>\n<li>Via Filter Fan Units<\/li>\n<li>Via open plenum<\/li>\n<\/ul>\n<p>When a HEPA \/ ULPA filter becomes saturated, it should be replaced without delay.
