Founded in 1987, Angel is a high-end water purification brand built by Shenzhen Angel Drinking Water Industry Group Co., Ltd. ... Since 1988 developed the first water purifier in China, Angel has obtained more than 700 patents at home and abroad, among which the self-developed three-year long-term reverse osmosis membrane technology has broken the monopoly of foreign technology.
Composite filter, the most widely used water purifier in Angel, is equivalent to one-piece ultrafiltration, and an ultrafiltration membrane is arranged outside with folded PP cotton and activated carbon to enhance the filtration effect. Among them, folding ultrafiltration membrane is used in the periphery, which can not only remove impurities, but also reduce the pressure of RO membrane filtration.
On the filter element of PP cotton, the traditional direct winding process was changed into a folding tube, which greatly increased the filtering area of PP cotton, effectively intercepted pollutants such as rust and eggs, reduced the impact on water flow speed and improved the flow speed.
Matters needing attention in using water purifier
1, the purchase of water purifier requires regular cleaning or replacement of internal filter elements. The replacement cycle of the first PP cotton filter is once every three months, and the front granular activated carbon filter, the rear granular activated carbon filter and the activated carbon filter are replaced once every six months.
2. After the water purifier is used, the ultrafiltration membrane filter should always be kept wet. If the ultrafiltration membrane filter is dry, the water yield will drop sharply and cannot be recovered. If you don't use the water purifier for more than three days, rinse the water purifier repeatedly for 2-5 minutes when you use it again until the water in the water purifier is used up.
3. The water purifier should be placed in a cool place to avoid direct sunlight. Because of the direct sunlight, cyanobacteria are easy to breed in the machine and affect the water quality.
