"The bags I got were original Nilfisk branded bags (contrary to other reviewers). Bag fits my Aero 26 so may fit all Aero machines. Packaging also includes a spare filter and some kind of elastic band\rubber gasket - not sure what that's for. Great bags at a great price."
"These are brand named for the Nilfisk machine. Excellent value from Screwfix, in fact cheaper than some non-branded bags. They are a good fit and great capacity even holding small brick, mortar rubble or using as a dust extraction for wood working. I have used a number of these bags and never had a problem with them. I purchased another pack for spares when they came back into stock."
"I use these bags daily on my refurbishment project together with a Nilfisk Aero 25-21 vacuum cleaner. The bags are affordable and I've never had one tear or break. Both the vacuum cleaner and bags have performed perfectly for very fine dust and rubble."
