These AF-CT paper dustbags suit the Cleanstar Starlite backpack vacuum cleaner as well as the Cleantech Piggy and Kerrick VH060 backpack vacuum cleaner as well as the Nilfisk DV1100 Domestic Backpack Vacuum Cleaner in a lime green and purple colour.

These have a membrane with a cardboard barrier, where the spout out of the lid pierces the membrane and delivers the dust into the dustbag.
