The EcoPor® dust bags represent environmentally friendly top technology. These bags reliably capture dust and dirt while conserving resources: made from recycled paper and plastic, the filter bags are primarily composed of recycled materials. EcoPor® is an anti-allergen filter developed by SWIRL® with a filtration efficiency of 99.99%. The filter not only traps regular household dust but also securely contains allergenic fine dust, such as pollen, mold spores, mite droppings, and bacteria. The indoor air is relieved of allergenic fine dust, allowing not only allergy sufferers to breathe easier. With the Dirtlock® dust closure, the bag can be easily sealed when it is full and needs to be changed. The closure prevents fine dust from re-entering the indoor air during the vacuum bag change. Thanks to Dirtlock®, the dust stays where it belongs: in the bag. Additionally, the holding plate is made from 100% recycled material.
