For a long, manual also did not say. Salesperson told me that my house has a small population can be used for two years and back to. Can my son said at least six months have to change a filter. "Who lives in Beijing's Chaoyang high Dashanzi worried-aunt has to tell reporters," I'm every glance retired home water purifier, the more I like a comfort machine. " Questions with high-aunt, "Fortune Times" reporter has visited Beijing's water purifier market. Found this to clean water and clean water production machine, because no And national standards, arbitrary collection of technical concepts fried products to fish to water purifier market is not standardized. Water purifier concept of random speculation , Cuiwei building and other home appliances That nearly 20 water purifier Including imported and domestic production of. These are basically two types of water purification machine, one is installed in the On the other is seemingly The drum-type. According to reports, no matter what kind of water purifier, water purification is achieved by filter function, filter adsorption and sub- To filter the water purifier is relatively cheap price, the price is generally more than 100 yuan to 300 yuan; membrane filter for water purifier large difference in price, 400 yuan to 5,000 yuan; one senior Membrane water purifier sold at more than 2000 yuan. Reporter found, however, whether the water purifier price of 100 yuan or 4,000 yuan a water purifier, the mark of technical concepts are very attractive. Gome Beitaipingzhuang in stores, the reporter saw a model Qinyuan water purifier products labeled "hydrophilic membrane" concept, another model claimed that "nano-films"; wave wooden water purifier is marked "hollow filter membrane "; beautiful body water machine play" pure crystal technology, "the word; Bette water purifier is that" digital "concept. In addition, the reporter also saw the "far "And" soft water "and other technical name of the water purifier. Water machine patterns occur repeatedly in the face of new terminology and technology The recommendation of staff glib, cheeky puzzled many consumers, Ruzhui clouds. Some consumers have identified a host of manufacturers leaflets, said the home carefully; some consumers simply to refer to the brand, price and appearance, was quick to buy; some consumers to seize the filter life of this vital issue asked one stop, but got the response was vague. Do not Let the water purifier into Reporters a few stores we have just heard, said sales to consumers, water purifier can be a year and back to filter. "A year for a filter, water purifier has become the comfort machine." Promotion of healthy drinking water of China Medical Professional Committee Officer Lee told reporters rehabilitation, water purifier and general electrical differences can not be once and for all. One filter from at least three months to more than half a change. This is because, regardless of what kind of filter, filter adsorption on both the large amount of organic matter, it is easy to become a breeding ground for bacteria, leading to deterioration of water purifier purifying effect. A study in Japan showed that activated carbon water purifier using the second day running that can detect micro-organisms, when run to 28 days, the number of bacteria per milliliter of water actually reached 120,000, far more than the safety of drinking water range. Bacteria can lead to water purifiers produce nitrification and denitrification, if not on the water purifier to clean and change batteries, water purifier nitrite levels can be higher than 7 times more than tap water, but nitrite is Killer. With the increasing use of time, water purifier adsorption capacity is also decreasing harmful substances, when the water purification machines rated more than the net amount of water, the water absorption of these substances are not only, will be released from the filter into the water. China Medical Foundation Health Professional Committee Lee rehabilitation of drinking water that the water purifier manufacturer sales personnel for consumers to buy products on the filter change time is extremely vague should not be, it is misleading to consumers. To make water purifier into the console Mozambican machine, a health assistant, rather than a healthy killer, using the water purifier should be based on different filter, in a certain period of time in a timely manner backwash. That let water flow through the membrane from the opposite direction, the adsorption of the membrane impurities washed away, the backwash of water generally should be the net amount of water has been produced twice, usually three months to clean. Lee revival speaking, the best of every six months with the reduction Agent disinfected once. "The best filter replacement." Water purifier production specifications call It is understood that water purifier originated in the early eighties of last century the United States, the nineties into the Chinese market.
