Buy water purifier to compare water quality difference

At present, there are two major types of water purifiers on the market. One is a water purifier (commonly known as pure water machine) that uses reverse osmosis (RO) technology. It has high filtration precision and can remove most impurities and harmful chemical components in water. The other type is a water purifier (commonly known as water purifier) ​​that uses activated carbon, ultrafiltration, microfiltration, etc., to remove impurities, bacteria, colloids, organic macromolecules and other substances in the water.

A few days ago, the Shenzhen Consumer Council selected two types and 10 brands of water purifiers for comparative testing. The test shows that although the water quality of the 10 water purifiers after the initial use and continuous use for a period of time all meet the requirements of the national standards, different types and brands of water purifiers have their own advantages and disadvantages, and the cost of use is significantly different.

The purchase price of the comparative test sample ranged from 998 yuan to 3298 yuan; the cost of replacing the filter element ranged from 367 yuan/year to 1355 yuan/year, and the cost difference was large.

From the functional point of view, the pure water machine has high filtration precision, can filter out most of the substances in the water (including harmful and beneficial), can only allow water molecules to pass through, and generally has double water discharge function, which can produce pure water and Clean water; but there are also disadvantages, such as a wastewater ratio of about 1:3 (about 4 liters of tap water is required to produce 1 liter of purified water), the tap water utilization rate is low, and the water output is small, and most of the electricity is consumed. The water purifier does not produce waste water, does not consume electricity, and has a large amount of water; however, the filtration accuracy is not as good as that of a pure water machine, and the filtration effect on inorganic salt substances is relatively weak, and there is only one purified water outlet.

Combined with the results of this comparative test, the Shenzhen Consumer Council reminded consumers to pay attention to the following points when purchasing water purifiers:

Choose well-known brand products. Judging from the results of this comparative test, the water quality of the well-known brand water purifiers is stable and reliable during the one-month test cycle (three tests).

Combine local water quality. When purchasing a water purifier, different types of water purifiers should be selected according to the water quality and the area. Want to remove most of the water, you can choose the pure water machine using reverse osmosis technology (such as the northern part of the water with higher hardness); want to remove impurities such as suspended solids, heavy metals, but retain some mineral elements, Choose another type of water purifier.

Measure usage costs. For different types and brands of water purifiers, comprehensive consideration should be given to factors such as performance, price, filter replacement cost, and after-sales service.

Pay attention to regular maintenance. Whether it is a water purifier or a pure water machine, the filter element needs to be cleaned or replaced regularly to ensure that the water purifier can perform its proper function and avoid secondary pollution caused by the failure of the filter function of the filter element.

Think of "direct drinking" rationally. For many propaganda that water purifiers can be directly consumed, consumers should look at it rationally. The comparative test found that among the 10 water purifier samples, the total number of colonies in the 8 water purifiers effluent was increased compared with the tap water. Therefore, consumers are advised to use the water purifier to boil and drink as much as possible to reduce the risk of drinking, especially children and the elderly with relatively weak immunity.
