[direct reporting network, Beijing, July 4 news Beijing Times recently, readers Ms. Jiang Xiang Jinghua home editing department reflect that she spent 4000 yuan to buy the Baojian brand water purifier, "it is said that can produce small molecules of water, easy to absorb. But in use, the merchant also told the ginger water purifier filter 7 to be replaced regularly, to spend 1500 yuan per year.

Ms. Jiang said that he bought water purifier is mainly for newborn babies, we all say that the filter is more safe." According to her introduction, buy water purifier of this kind of product without understanding, and listen to the acquaintances choose Baojian brand products. And the product in the ordinary commercial super and large electronic business platform is not sold.

Last September, Ms. Jiang contacted the brand sales staff through friends Jian song, the door installation. Water purifier for some time, the sales staff also told Ms. Jiang, water purifier filter is required to be replaced regularly, the core price is 1500 yuan a year. "Water purifier is expensive, and every year to spend 1500 yuan!" the cost of this is beyond the expectation of jiang. Ms. Jiang said she did not know before buying water purifier in the future to change the core, the sales staff has never mentioned, even the door installation workers did not say. Later gave me a list, said to be based on the date of the above tips to replace the filter."

At this point, Ms. Jiang search after a look at other similar water purifier products found, generally 5 - 3 layers of filter, and the price is about one thousand or two thousand yuan." Their buying only ordinary domestic products, "4000 yuan is not been fooled?" in addition, for seven layers of filter settings, Ms. Jiang also has the different idea, the more layers, follow-up for core prices higher, businesses have suspected of deliberately designed filter make money. " "1500 yuan enough to buy a new machine for individual brands." In the meantime, the water purifier actually leaked a water, flooded the kitchen, which makes her more skeptical about the quality of water purifier. So, Ms. Jiang contacted the song, ask the effect of the water purifier in the end how. Song again to appease Ms. Jiang said the water after the product is filtered into small molecules of water, but also rich in minerals and trace elements, very suitable for the elderly and children. Hear this explanation, Ms. Jiang and determined to continue to use.

However, the quality of the water purifier into her heart. Recently, she pulls out a product packaging found small molecule, easy to absorb other propaganda, not in equipped with the product brochure. Later, the sales staff through WeChat sent to her Guangdong local CDC issued a screenshot of the water quality testing report, which indicates that the water quality in line with national standards. "What can this report prove? If we want to test the quality of our products?"

Ms. Jiang on the water purifier home is now full of doubt, I do not know which 4000 yuan spent is right or wrong.

Miss Jiang's doubts, when the JINGWAH Times reporter asked him to produce a shopping voucher, but her face is blank. In addition to install at home products, packaging and some brochures, nor what she was shopping vouchers. According to its introduction, and sales staff are usually the phone, WeChat contact. On the day of the installation of the payment of the purchase price of 4000 yuan, but never someone gave her a invoice, contract and other shopping vouchers.

By JINGWAH Times reporter to remind, Ms. Jiang and sales staff, said to make up the invoice or receipt. Start each other Mankoudaying, but as of press time ago, the other no reply.

JINGWAH Times reporter from the materials provided by Ms. Jiang, the purchase is only an ordinary home ultrafiltration water purifier. In the product packaging, the implementation of the standard, as QB/T4143 - 2010 "household and similar use ultrafiltration water purification machine", approval wading batch Wei Yue water [2014] the S1833,. But businesses did not provide consumers with health documents relating to the original or copy.

Ms. Jiang's home to buy a water purifier ultrafiltration. First of all, the main means of filtering direct drinking water is ultrafiltration, nanofiltration and reverse osmosis three categories. Their membrane accuracy from low to high. In brief, ultrafiltration is the lowest level of filtration. And the function of ultrafiltration water purifier also is the removal of large particles of impurities, such as silt, part of the chemical pollution, heavy metals, organic matter and scale is not removed. But it can keep the minerals in the water. The whole price is cheaper, and no electricity, no waste water.

There is also a kind of pure water machine, the price is high, want to use electricity, and there is waste water rate. But it can through the reverse osmosis membrane, remove the water most of the harmful and beneficial substances, such as organic matter pollution, heavy metals, minerals, scale, and so on, filter class higher and safer.

From the above concept presumably we have learned that the use of the ginger lady is only one of the filter level is not high water quality processor. As for the price, as mentioned above, due to the filtration technology is not high, so the relative reverse osmosis water purifier filter is generally cheaper. But the Jinghua Times reporter in an electronic business platform of proprietary brand ultrafiltration water purifier comparison found that "Baojian" the industry experts said "have not heard of the brand, with the price of 4000 yuan to catch up with the part of the international big name imported similar products (not found seven stage filter products, the business platform for the sale of products the highest element number 6). Even more than some well-known domestic brands of reverse osmosis pure water machine is also higher than one thousand or two thousand yuan.

As for the core price, Western brand price also really is not low. A reporter from the online store to see only a PP cotton price is 100 yuan, according to Bao Jianjing
