Nilfisk VP300 and VP400 Commercial Vacuum Cleaner Replacement Sack Main Filter
Replacement barrier sack filter, for the Nilfisk VP300 HEPA and the new Nilfisk VP400 commercial vacuum cleaner.
These shouldn't be washed, just gently vacuumed should they get dusty.
As a rule of thumb, the dustbag filters out dust greater than 50 microns, about the diameter of a human hair. This filter probably filters down to about 8 microns, and protects the HEPA filter.
The HEPA filter will filter down to .03 of a micron, and should probably be replaced each couple of years.
