High-Efficiency Filtration: The precise non-woven surface layer and inner melt-blown non-woven fabric are equipped with silver ions, which can easily filter large dust particles. At the same time, they help reduce unpleasant odors. Premium Activated Carbon: The addition of activated carbon components effectively absorbs odors. Good Seal Design: High tightness prevents leakage of ash or dust, ensuring that particles captured by the vacuum bag are not released back into the air. Effective Filtration: The dust bag is made of melt-blown fabric and non-woven fabric, working with the cleaning station to capture 99.7% of ultra-fine dust particles as small as 0.3 microns. Auto Lock Feature: Automatically seals when the dust bag is lifted, locking the inlet to contain dust and dirt inside the bag.
