Molekule Air Mini+ features 360-degree air intake that replaces the air in a 250-square-foot room every hour. Its designed to sit on an elevated surface like a table or counter and pull in pollutants from all sides. The device uses a patented PECO-Filter, which is coated with a proprietary catalyst and breaks down VOCs, bacteria, mold, viruses, allergens, and other pollutants at a molecular level when activated by light. The sensor in Air Mini+ is designed to detect particles, giving you a window into the air quality of the room its operating in.
