The Kirby has been around for awhile. With two shedding dogs, we had a full vacuum bag and needed new ones ASAP. We got these bags quickly and they made the difference with suction.They're genuine Kirby bags.They work as expected.For the count and the price Ill be ordering again in the future!Fit as they should and have had no issues with these.I liked that I didn’t have to run all over town looking for my sweeper bags.These work better than the generic ones.Great vacuum and bags make the differenceWork well! Thanks!Good value for the price.These do the job, as you would expect of Kirby ...one tip though, they can be tight to fit to the pipe inside, so just smear a little washing up liquid on the pipe first.After 20 years in storage and a move from the tip of the African continent, we found our faithful Kirby G4 and needed bags, My partner has never had so much fun de-dusting our victorian villa, As they say, you only buy a Kirby if you either own a hotel or are a dust freak! Kirbys are not cheap but they are the best. The bags supplied by Amazon fitted perfectly and we now live in a perfectly dust-free victorian villa which suits me no end since I have a nasty case of COPDThese were not the same as I have had before from Kirby Vacuum bags.One's I have had in the past were made of a form of cloth, not paper.and were allergen reduction filters.Although both packages say "Micron Magic" they are not of the quality I was expecting from the last ones received.For a proper dust removal you must use the original bags.They were the Kirby ones for the vacuum cleaner. Excellent service from the seller.
