The unique features of the s-bag® Anti-Allergy are: Anti-allergen effect: s-bag® Anti-Allergy protects your health, contributing significantly to the hygiene and air purity of your home, while still maintaining excellent performance. s-bag® Anti-Allergy reduces the exposure to allergens and the risk of allergies in your family. High filtration capacity: s-bag®Anti-Allergy has high filtration to capture pollen, dust particles, dust mites, mite allergens and cat allergens as small as 1 micron (15 times smaller than the diameter of a human hair). This level of filtration is of benefit to asthma and allergy sufferers. Powerflow™ s-bag® is 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. s-bag® is also available in different materials to fit your needs and to optimise your vacuum cleaner performance: Classic Long Performance, Anti-Odour 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® Hygiene Anti-Allergy vacuum cleaner synthetic bags. Reference also known as GR206S
