The Dustblocker 650 G4 front filter is the secondary filtration stage, removing fine dust from the air before the very finest particles are asorbed by the final G4 main HEPA filter.
G4 front filters are designed to remove fine dust from the air, leaving only the very finest and most harmful particles to be trapped by the main HEPA filter. This prevents premature clogging - thus reducing replacement costs.
Genuine MAXVAC accessory DBF1011.
