The Filtero bags turned out to be just as good as the branded bags for my Vitek vacuum cleaner. In vain I was worried that they would not fit, would not fit snugly and that all the dust would accumulate not only in the bag . In fact, everything turned out to be the opposite. It even seems to me that the power of the vacuum cleaner itself has increased, and it does not decrease as the bag is filled. Apparently such an effect is due to the fact that the bags are five-layer, made of a special material. Waiting for the item to be in stock!
