This invention discloses an air particulate matter separation device and method. The device includes a fan, a purified water chamber, and a multi-stage separation chamber. A filter element is installed within the multi-stage separation chamber. The fan blows air carrying dust particles into the multi-stage separation chamber, causing the dust particles (calcium carbonate particles) to be filtered onto the filter element. The multi-stage separation chamber is connected to a first gas separation mechanism, which in turn is connected to the purified water chamber. The purified water chamber stores distilled water. The first gas separation mechanism separates carbon dioxide from the air and inputs the carbon dioxide into the purified water chamber, converting the distilled water into carbon dioxide-containing water. The purified water chamber is connected to the multi-stage separation chamber, and the filter element is rinsed using this carbon dioxide-containing water. During physical rinsing, carbon dioxide, water, and calcium carbonate react to form calcium bicarbonate dissolved in the water, effectively removing dust particles adhering to the filter element, preventing filter pore clogging, extending filter element life, and avoiding frequent filter element replacements.
