The Dustblocker 650 G3 pre-filter is the first filtration stage, removing the largest particles from the air before finer dust is removed by the subsequent G4 front filter and final G4 main Hepa filter.
G3 Pre-filters are designed to remove the largest particles from the air, which helps to prevent front and main HEPA filters from becoming prematurely clogged - thus reducing replacement costs.
Genuine MAXVAC accessory DBF1010.
