The Swirl MicroPor Plus anti-allergen filter not only captures regular household dust but also allergenic fine particles such as pollen, mold spores, mite droppings, and bacteria in the bag. This means that allergy sufferers are relieved from allergenic fine dust in the indoor air. The Swirl carrying handle bags contain an antibacterial agent that stops the growth of bacteria in the bag and inhibits unpleasant odors, making them suitable for the Hoover Telios Extra model.
