The EcoPor® dust bags represent environmentally friendly cutting-edge 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, dust mites, and bacteria. This reduces allergenic fine dust in the indoor air, allowing not only allergy sufferers to breathe easier. The Dirtlock® dust closure allows the bag to 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.
