Prima bag at an unbeatable price! Replace the bag perfect for my Philips vacuum cleaners and cost only a fraction of the original bag. A difference in terms Saugqualität and cleanliness can not be established with the best intentions. I am allergic and had to while vacuuming always watch a little, with these bags there is no reason, they seem fine filter. If my package is all, then I'll just re-order these bags.
