The unique features of the s-bag Classic Long Performance are:
Long lasting performance: s-bag Classic Long Performance lasts 50% longer than traditional vacuum cleaner paper bags.
60% more suction power: the resistant synthetic material of s-bag Classic Long Performance ensures optimum air flow and gives your vacuum cleaner constant suction power as the dust bag fills up.
High filtration capacity: the synthetic material of this vacuum bag filters most of the up to 99% of particles as small as 1 micron (15 times smaller than the diameter of a human hair). It filters the air 40% more efficiently than a normal paper bag and helps you get rid of airborne particles such as allergens and some bacteria.
Designed with a special folding that gives it more capacity vs. a flat bag. Powerflow makes the bag flexible and easier to fit in the vacuum cleaner.
Improved closing system – durable and hygienic: The closing system has been re-designed, and made more rigid by using stronger material and a new sealing technology. This to ensure the s-bag closes every time and doesn’t break or leak.  This vacuum bag is easy to fit in the cleaner, and hygienic as the bag automatically seals when removed, preventing any spillage and making bag changes quick and clean.
Anti-Odour, Anti-Allergy and Ultra Long Performance.
For optimum performance, bags should be changed regularly and filters should be changed with every 4th vacuum bag. All filters should be replaced at least twice a year or when they become visibly soiled. The use of non-genuine s-bag vacuum bags may adversely affect the performance of your vacuum cleaner.
This pack includes 4 s-bag Classic Long Performance vacuum cleaner synthetic bags.
