Do you understand the professional words in the water purifier logo?

Recently, the Guangxi Food and Drug Administration announced the list of unqualified enterprises in the first quarter of 2015, and the batches of 289 batches of bottled water were unqualified. The unqualified items were the total number of colonies. Pseudomonas aeruginosa, total arsenic, the safety of drinking water for a time has become a hot spot of public concern. However, the reporter found in the survey that in addition to drinking bottled water, many people choose to install a water purifier in their homes, such as “activated carbon”, “microfiltration”, “ultrafiltration” and “reverse osmosis” in the water purifier promotion. Professional vocabulary is also to let consumers in the clouds, how to choose a water purifier, we also listen to the advice of the industry.

Look function

High-grade water purifier filtration accuracy of up to 0.0001 microns

The reporter saw in an electrical appliance store in Nanning that the water purifiers of more than ten brands including Midea, Angel, Smith, Gree, 3M and Yikou were placed in a conspicuous position. The price was as low as several hundred yuan, and the high was over ten thousand yuan. . Reverse osmosis, ultrafiltration, small molecular clusters, weak alkaline... The function of the water purifiers in the forest, so that reporters do not know how to choose.

According to the law enforcement personnel of the Autonomous Region Health Supervision Institute, the simplest water purifier is a filter core structure, but in the assembly, it is equipped with a pre-filter that can remove large impurities in front of it, and the filter core is sterilized and removed. Odor and absorption of impurities in one. The other is relatively complex. It consists of five filter cores. The five filters of PP cotton, ceramics, ultrafiltration membrane, activated carbon and reverse osmosis are responsible for filtering scale, bacteria, heavy metals and odors. The role.

The insiders told reporters that the main function of the water purifier is "filtering", which is to purify the water "clean" through the safest physical methods. The core component of the water purifier is the filter membrane. The smaller the pore size, the better the purification effect. The main filtration membranes currently on the market, from small to large pore size: reverse osmosis (up to 0.0001 micron), ultrafiltration (0.01 micron), microfiltration (0.2-5 micron).

How to choose a household water purifier?

Industry insiders come to the trick

How do consumers choose to face a wide range of water purifiers?

The law enforcement officials of the Autonomous Region Health Supervision Office said that the water purifiers currently sold in the Nanning market and supermarkets are relatively standardized. When consumers purchase, if conditions permit, try to choose a big brand of water purifier, such as Yikou water purifier.

In this regard, the industry also gave their own advice, the purchase of water purifiers, first of all should be based on the size of household water consumption to choose the appropriate specifications. Secondly, the appropriate water quality processor should be selected according to the regional water quality. It is best to choose a branded product. Most notably, as the core of the water purifier - the filter element needs to be replaced regularly to avoid the use of bacteria for a long time, which will affect the quality of the water. Finally, the professional installation service is also very important! Professional installers provide professional door-to-door Installation and commissioning ensure that the water purification products can fully utilize the filtration performance.

Filter the material efficiency from the water purifier:

PP cotton: It can filter rust and relatively large sediment, and the filtered water can not be drunk directly;

Granular activated carbon: It can adsorb residual chlorine and organic matter in water. The filtered water is not recommended for direct drinking;

Ceramic membrane: can filter bacteria, rust, sediment, residual chlorine, macromolecular organic matter, etc., filtered water can theoretically drink directly;

Ultrafiltration membrane: It can filter bacteria, rust, sediment, residual chlorine, macromolecular organic matter, and can filter out mineral water and reach the standard of direct drinking.

Reverse osmosis membrane: It can intercept more than 0.0001 micron. It is the most precise membrane separation product. It can filter harmful substances such as heavy metal ions, bacterial viruses, volatile organic compounds, etc., and obtain pure water. The layers are precisely filtered. The filtered water does not need to be heated. You can drink. Chen Jiajia
