ProFilters - The new generation of replacement nonwoven dust bags for industrial and professional vacuum cleaners. Dust bags made of nonwoven material. Our dust bags are characterized by higher durability and resistance to a blow-out when compared to paper dust bags. Thanks to the application of the special filtering nonwoven material ProFilters dust bags adapt easily to the shape of the vacuum cleaner’s container, which enables making the most of its capacity. After turning a vacuum cleaner off the dust bag settles due to its elasticity – fine dust settles on the bottom, and when a vacuum cleaner is turned on again its thrust is still high. A ProFilters dust bag’s capacity can be used in 100% , whereas ordinary paper dust bags lose their suction power when only partly filled. Therefore ProFilters dust bags can work 2-3 times longer than ordinary paper dust bags.
