Since the Miele vacuum cleaner bags but are a bit expensive, I simply chose the much cheaper option of turning Flex. I was not disappointed. One bag will cost 50ct converted that they respect as long as the originals. As a strong house dust allergy I had concerns about the fine filter function. But everything was great, no increased sneezing and Pfeifatmen after sucking. The only drawback is the bag of box holders, one fixed with the bag in the unit. For over ten times change me a pouch is torn on cardboard. But that may be due to gruff pulling out from the pack, etc. And in 50ct loss I will pull for no star. Have already recommended the bag.
