The quality of Angel water purifier is okay.

Angel was established in 1987. It is a high-end water purification brand created by Shenzhen Angel Drinking Water Industry Group Co., Ltd. Since Angel developed China's first water purifier in 1988, it has won more than 700 patents at home and abroad. Among them, the long-lasting reverse osmosis membrane technology independently developed over three years has broken the monopoly of foreign technology.

The most widely used US composite filter element of Angel water purifiers is equivalent to integrated ultrafiltration. An ultrafiltration membrane on the outside is paired with folded PP cotton and activated carbon to enhance the filtration effect. The periphery adopts a pleated ultrafiltration membrane, which can not only remove impurities but also reduce the filtration pressure on the RO membrane.

On the PP cotton filter element, the traditional straight-rolling process is changed to a folded cylindrical shape, which greatly increases the PP cotton filtering area, can effectively intercept pollutants such as rust, insect eggs, and also reduces the impact on the water flow rate. , improved traffic.

Precautions for using a water purifier

1. When purchasing a water purifier, you need to clean or replace the internal filter element regularly. The first PP cotton filter element is replaced every 3 months, and the pre-granular activated carbon filter element, post-granular activated carbon filter element and activated carbon filter element are replaced every 6 months.

2. The ultrafiltration membrane filter element should always be kept moist after use. If the ultrafiltration membrane filter element dries out, it will cause a sharp drop in water production that cannot be recovered. If the water purifier is not used for more than three days, when it is used again, the water purifier should be flushed repeatedly for 2-5 minutes until the water in the water purifier is drained.

3. The water purifier should be placed in a cool place without direct sunlight. Because of direct sunlight, blue algae can easily breed in the machine and affect the water quality.
