DFS uses a proprietary technology that prevents bacteria growth from building up on your air purifier. Although true HEPA air purifiers expel fresh air, they don’t do anything to keep the filter itself clean from contracting mold and other bacteria from growing on the filter.
By preventing growth, DFS also prevents live organisms from escaping back into the air. In effect, by using this technology you are improving your air without exposing yourself and others to harmful bacteria growth.
