Some time ago, the mother found out that she had stones. She usually drank a lot of water. She suspected that she had water quality problems. Therefore, she recently wanted to purchase water purifiers at home. However, she went to several home appliance stores and found that there are many styles of water purifiers and the functions are complex. , The price difference is also large, they do not understand at all, I do not know how to choose. 'A few days ago, Mr. Guan sent his doubts about the water purifier to the circle of friends for help. With Mr. Guan's doubts, the reporter recently visited the area. A number of home appliance stores. In the sand home appliance stores, the reporter saw a lot of water purifier products. These water purifiers, whether brand or price, are dazzling, the publicity on the products is full of tricks. Consumers who don't understand the water purifier cause 'Mengcha' feeling.
In a brand water purifier counter, the reporter saw that there were 4 filter cartridges inside a water purifier hung on the wall, respectively marked PP cotton filter, pre-activated carbon filter, silver-loaded activated carbon filter, ultrafiltration membrane filter. For these filter efficiencies of the water purifier, the reporter did not understand it and asked the sales staff. The salesperson Ms. Liang explained to the reporter that the water purification products on the market can be classified into adsorption type, filtration type, ion exchange type, and Penetration type, etc. She said: 'Adsorption type activated carbon filter can remove heterochromatic odor in the water, residual chlorine and colloid.

The taste is similar to mineral water
For the salesman's introduction, the reporter was skeptical, and the two customers beside him said they did not understand. In order to dispel doubts, the salesperson Miss Liang invited the reporter to experience the effect of the water purifier together with the customer. Miss Liang took a glass of tap water from the faucet. Then, I took another cup of water from the water purifier and placed it in front of the reporter and the customer.

On the palate, the reporter felt that this glass of water was not much different from the quality bottled water in his own home, and it smelled of unpleasant smell of chlorine in tap water. It was almost the same as bottled mineral water sold outside the market. Miss Liang explained that: After 4 layers of filtration, the water purifier basically removes inorganic, organic compounds, heavy metals, pesticides, solvents, nitrates, chlorine, lime and other impurities in the tap water, so the taste is not worse than that of domestic bottled water or mineral water. Can be directly consumed, so now more and more people choose to buy water purifiers in order to improve the quality of home drinking water. '
Filters need to be replaced regularly
'The filter element of the water purifier filters so many impurities. Will it be very dirty. Will it be too hygienic for the drinking water to exceed the standard for a long time?'

If the filter cartridge of the 'extended service' is not replaced in time, it will not only fail to achieve the purification effect, but will also cause harm to the human body. 'After tap water passes through the water purifier, a large amount of residual water will remain. The impurities on the water purifier filter element, these impurities will cause the 'secondary pollution' of the water, which means that after a period of time, the water from the water purifier may be more dirty than the tap water, so it needs to be replaced regularly. Water filter to ensure the cleanliness of water quality. ' Miss Liang said that in the replacement of filter elements, the public can determine the specific replacement time according to their own family water consumption and water quality. In general, PP cotton 4-6 months, before Activated charcoal 8-12 months, ultrafiltration filter 18-24 months, RO reverse osmosis membrane 18-24 months, post activated carbon 12-18 months.
