How to choose? Four steps to see
When the street well, Xiaoquan village, Dayuanqiao, Qianxi Road and so on are rich in "water vapor" place names, telling the old generation can not be separated from the normal state of well water, stream water. Nowadays, well water and stream water have long gone, and another kind of "water life" has gradually become the new favorite of home decoration after the 80s - household water purifier. However, there are many kinds of water purifiers on the market, and their functions are different. How to choose a suitable water purifier?
Good sales, can sell thousands of units a week
The old week is made by selling water purifiers. Ten years ago, he took a brochure and carried out a cumbersome prototype to sell it, and he couldn’t sell one piece of his skin. The maximum sales volume per year was no more than 10. Ten years later, Lao Zhou opened an online shop, sat in front of the computer, hired 4 customer service, and moved his fingers. The weekly sales volume was thousands. In his words, after the formation of the family after the 80s, the "spring" of the water purifier came.
Enter the keyword “tap water filter†on Taobao.com, showing that there are more than 112,000 related products in the whole network. The “leaf water purifier†sold by a shop in Tmall Mall has recently sold 11,638 pieces. The shop owner said that at present, most people choose activated carbon filters, the most effective reverse osmosis water purifier, the price is slightly higher, the volume is not high.
In large-scale electrical stores, branded household water purifier equipment generally requires professional installation, the average price of two or three thousand yuan, "now new decoration, generally installed water purifier, young people buy more, sell at least five or six units a week "A salesperson at an electrical appliance store said.
More miscellaneous brands, leaking into a big dispute
According to the statistics of the China Household Electrical Appliances Association, at present, there are more than 3,400 domestic water purification products manufacturers, but there are only more than 900 production licenses, and there are only a handful of well-known water purification brands in the country.
In addition, the concept of water purification market is constantly changing, ultrafiltration, soft water, reverse osmosis, nano energy... all kinds of water purification terms are dazzling, most of them claim to have the latest water purification technology, the price ranges from several hundred to several thousand . There are many disputes caused by water purifiers, the most common is water leakage.
Ms. Duan bought a household water purifier on the Internet, and the decoration master took the installation tutorial video on the ipad and took it in ten minutes. After half a month, the busy renovation ended, Ms. Duan took a sigh of relief and ended up receiving a community call. “Community let me go and see, our water leaks have affected the downstairs.†Ms. Duan rushed to the new home. The corridors were filled with water. The ceilings of the neighbors were all water stains, and the water kept going. Drop down.
The community staff helped the lady to find a leak. Go to the bathroom first, no leakage; problems found under the kitchen sink, water leaks in the water purifier and faucet joints, the valve has been closed, and the joint position is still “tickingâ€. Ms. Duan asked someone to unscrew the joint and found a crack in it.
"The solid wood floor is all broken, and there are furniture, plus the loss of the neighbors, at least 10,000 yuan. Going online to find the seller, people say that it is caused by improper installation. Consumers said that the responsibility is not good." Ms. Duan was almost mad.
Lack of standards, water quality is good or not
Due to the lack of mandatory inspection and testing standards, the water purifier has no effect, it is really not accurate.
"There is a water purifier installed at home. I think that the purified water is definitely clean, so I will drink raw water directly." Xiaozheng installed the water purifier for 3 years. He changed a new filter device every year. Recently, his stomach has been It became fragile. "I often have diarrhea. It is the same for all three meals at home. It is better to not drink raw water. I began to doubt the effect of the water purifier."
At present, the water purifier industry only has industry norms, including the “General Water Quality Processor Health Safety and Function Evaluation Regulations†issued by the health department, “Sanitary Safety and Functional Specifications for Drinking Waterâ€, etc.; national standards have not yet been officially released.
According to industry insiders, the structural principle of the water purifier is not complicated. Small manufacturers can purchase filter devices such as filter cartridges and install the outer casing. Material differences are difficult to distinguish with the naked eye. The quality of household products is good or bad, and there is no accurate indicator guarantee.
At present, the household water purifiers on the market, one is a pure water machine, which filters out most of the water in the water, which is equivalent to the bottled pure water on the market. This is currently considered to be the safest water treatment method. The filtered water can be directly consumed; the second is a water purifier, which can partially or completely filter out harmful substances in tap water, such as residual chlorine, impurities, odor, heavy metals and bacteria, as well as rust, viruses, colloids, etc.; It is a pre-filter that uses a strainer to intercept impurities deposited in a water pipe to improve the quality of tap water entering the house. This is the biggest sales volume of online stores. Xiao Zheng chose this type of water. The water filtered by it cannot be directly consumed.
Learn a trick
Four steps to pick the water purifier
1. Is there an authority certification?
Try to select well-known brands. These products have been appraised by the national health and technical supervision department, which meets the national water purifier water quality standards and are more reliable. At present, most of the mainstream water purifiers are certified by authoritative departments. Some well-known brands have passed the test of the National Sanitation Foundation and have obtained the nsf/ansi61 standard certificate.
2. Filter technology can be unreliable
One of the most critical components of a water purifier is the filter element, which is a key component in determining the water purification effect.
At present, there are three mainstream water purification technologies in the market: ro reverse osmosis, ultrafiltration, and microfiltration. Among them, the filtration membrane diameter of the reverse osmosis membrane is 0.0001 μm, the filtration membrane diameter of the ultrafiltration membrane is 0.01 μm, and the filtration membrane diameter of the microfiltration membrane is 0.1 micron. All three water purification technologies can filter bacteria 100%, and the ultrafiltration membrane is said to retain trace elements beneficial to the human body.
3. Provide system professional services
As the saying goes in the industry, the water purifier is a "three-point product, seven-point installation."
The merchants with excellent service will provide the purchaser with a personalized water purification plan for the family, and will regularly change the filter after the sale. The water purifier is used for a long time, and the filter element is easily blocked by impurities, resulting in re-contamination. At present, the frequency of water purifier filter replacement is changed once every 6 months, 8 months, 1 year, 2 years, 3 years.
A brand-name water purifier that does not have professional service capabilities, although it does not hesitate to put the samples and the exhibition hall to look like a decent, but the troubles in use follow. For example, the installation requires additional charges, confusion in the installation process, and hidden dangers in the water and electricity pipelines.
4. Pay attention to the material of hardware accessories
If the hardware is out of order, it will not be exposed until after a while.
There are several large water purifier brands on the market, most of which are also big-name hardware accessories. The hardware accessories have passed the strength test, salt spray corrosion resistance test and load fatigue test. Many miscellaneous products in the market use low-end hardware accessories, the difference between the outside viewing is not big, but because of the low price (the cost is less than one-tenth of the quality imported brands, the process materials are rough), it is easy to rust, loose, deformed, leaking.
