what do you mainly look at when choosing a water purifier? Many people may be confused. They don't know the working principle of the water purifier, and they don't know where to start when choosing it. In fact, the following points are the main points to choose a water purifier. ● understand water quality. This is a necessary principle. The hardness of water quality varies in different regions, so you should first understand your own water quality before buying. The tap water quality in most urban areas is good, so you can choose a filter water purifier; However, reverse osmosis water purifiers can be purchased in heavily polluted areas with chlorine and heavy taste in the water, or families with direct drinking needs. ● see the product certificate. The manufacturer producing the water purifier must obtain the hygiene license issued by the superior hygiene supervision department, which meets the requirements of the "Specification for sanitary function and safety evaluation of drinking water quality processors — — general water quality processors". In addition, Lu Jianguo stressed that the electrical safety of the water purifier should have a test report that meets the requirements of the national standard gb4706.1-2005 safety of household and similar electrical appliances Part 1 General requirements; The product performance shall have a test report that meets the requirements of qb/t4143-2010 ultrafiltration water purifier for household and similar purposes, or qb/t4144-2010 reverse osmosis water purifier for household and similar purposes. ● know the filter of water purifier. Read the instructions or communicate with the shopping guide to understand the substances that the water purifier can filter. Generally, it should be able to filter chlorine, sand, heavy metals, etc. If you have special needs, you should find one that matches your situation. For example, in the high hardness water quality of northern China and the limestone area of southern China, the content of calcium and magnesium ions in the water is high, and it is easy to scale. Therefore, advanced filter water purifier with ion exchange resin filter element should be selected. For urban tap water with chlorine, heavy heterochromatic odor and high organic content, domestic water purifiers with high activated carbon load can be purchased. ● see the waste water rate. Check whether there is a test report from the national accreditation body, and whether it is marked with the detailed manufacturer and the wastewater rate of the water purifier. For similar water purifiers, try to choose one with low wastewater rate. ● check the purification capacity of the filter element. The quality of water purifier mainly depends on the filter element. Consumers can know from the manual how much water the filter element can purify at one time, and then buy it according to demand. It should be reminded that the service life of filter elements of different water purification technologies and processes is also different, and the actual service life depends on the local water quality, frequency and quantity of use. Frequent flushing is conducive to extending the service life of the filter element of the water purifier
