The EcoPor dust bags represent environmentally friendly cutting-edge technology. These bags reliably trap dust and dirt while conserving resources: made from recycled paper and plastic, the filter bags are largely made from recycled materials. EcoPor is an anti-allergen filter developed by SWIRL with a filtration performance of 99.99%. The filter not only traps normal house dust, but also allergenic fine dust such as pollen, mould spores, mite droppings and bacteria safely in the bag. The room air is relieved of allergenic fine dust, so that not only allergy sufferers can breathe easy. The Dirtlock dust seal makes it easy to close the bag when it is full and needs to be changed. The closure prevents fine dust from being released back into the room air when the hoover bag is changed. Thanks to Dirtlock, the dust stays where it belongs: in the bag. The retaining plate is also made from 100% recycled material.
