Abstract
An air-purifying device for a front-opening unified pod to purify the air in it is provided. The air in the front-opening unified podis sucked through one of its breathing holesand directed into an air-purifying device (M) that includes a fan-driving means, a dust-filtering means, and a chemical-filtering means. The moisture, chemical gases, and dust in the air are removed by the air-purifying device (M), and then the purified air is forced into the front-opening unified podthrough the other breathing hole. Thus the air in the front-opening unified podis purified, and its purity is maintained by circulating the air.
