Pre Filter

Pre filter / primary air filter

As their name suggests, pre filters are responsible for filtering out the particulate in air before it gets to the HEPA or ULPA filters. Generally, these remove larger particles. Using pre-filters is also a great way to extend the life of your HEPA filters, as it makes the HEPA filter work less. 


If your filtration system has pre-filters, it's good practice to change them about 6 times a year, or every other month. This will keep everything in your filtration system running smoothly, and will ensure that none of the cleanroom system parts past the pre-filters experience excessive contamination.
