The filters of the Karcher vacuum cleaners help to reduce the level of air pollution, with special filters that capture even the smallest dust particles. The exhaust fine filter is mounted on the outlet inside the vacuum cleaner and is designed to release hygienically clean air. A high-efficiency HEPA filter is used as such a filter. The Karcher filters are made of high-quality materials. The flat pleated filters of the Karcher vacuum cleaners ensure a cleaning efficiency of up to 99.9%. The filters provide effective air purification by significantly reducing dust, pollen, pet droppings and other allergens in the air you breathe.
