These Purex Pre-filters are designed to capture larger particles before they can enter the main HEPA filter. Graduated fiber matrix delivers excellent particle cpature capacity - up to 20 times more than a standard filter. The main filter life would be much shorter without pre-filters, therefore these would be an asset to anyone using these units.
