Users must be aware of the importance of product quality when purchasing water purifiers. Provisions of the Measures for the Supervision and Administration of Drinking Water Hygiene; The manufacturer of the water purifier must obtain the hygiene license from the health supervision department at a higher level (as shown in the figure, it is identified by the technical supervision department and meets the national drinking water quality standard). At present, there are about 45,000 water purifier manufacturers in the water purifier industry, of which 80% are unqualified small workshop enterprises. Without health approval, the quality of products is unqualified, and many manufacturers are in danger of closing down or being returned at any time.
Two: it is very important to choose qualified filter elements.
Filter element is the core component of water purifier products, which is related to the quality of filtered water of water purifier products. At present, domestic first-line brands mostly use RO reverse osmosis filter elements such as Dow filtration and Han Shi filtration, and the R&D manufacturers of ultrafiltration filter elements are well-known domestic manufacturers such as Angel and Li Sheng. The brand of Ouen water purifier adopts German technology, and the core product adopts international excellent Han Shi filter element to ensure healthy drinking water safety for families.
Third, is there a safe and effective sterilization technique?
At present, there are two ways to disinfect water purification equipment. One is to add disinfectant, which can kill some bacteria, but contains trace chemicals harmful to human health; Second, ultraviolet sterilization is one of the internationally recognized effective sterilization technologies, because ultraviolet sterilization is safe and efficient, and can quickly kill almost all bacteria; Moreover, ultraviolet sterilization adopts physical principles, does not need any chemical agents, and has no side effects on human body. The third is to remove bacteria and viruses from water by pure physical filtration, such as OWIN water purifier products. The front end is partially adsorbed and disinfected by high-quality compressed carbon and activated carbon, and at the same time, it is physically filtered by Han Shi membrane, the core component of the water purifier, and the purified water without any impurities comes out.
4. Whether there is a perfect after-sales service system.
The after-sales service system is very important: at present, there are many counterfeit products on the market, and the products of small brands and miscellaneous brands can not achieve the effect of direct drinking. Once something goes wrong, agents and manufacturers close their doors and leave. Some manufacturers do not have a perfect after-sales service system, which makes consumers and agents very helpless. You should know that the replacement of filter elements and the untimely maintenance service will cause great harm. Ouen company has been adhering to the advanced service concept, bringing unique 7-level service to our customers: Love-humanized service; ? Comfort-shopping guide service; ? Careful-nanny service; ? Rest assured-quality assurance service; ? Private archiving service; ? Intimate installation service; ? Peace of mind-after-sales service. With your concern and encouragement, we will do better!
Verb (abbreviation for verb) Do you have your own core technology and R&D team?
Some manufacturers have assembled or branded water purifiers. In order to maximize profits and continuously reduce costs, the quality of products is not guaranteed by using inferior equipment. Manufacturers without production will not have good after-sales service, because after sales, manufacturers have to bear the cost and purchase spare parts. Many parts suppliers keep changing, and the quality is not guaranteed. And many manufacturers are unwilling to do after-sales, and consumers are still very hurt. Therefore, the choice of water purifier manufacturers must choose enterprises with production, technology and research and development.
Sixth, buy a cost-effective one.
In fact, the more filter elements in the water purifier, the better. It's important to look at the model. For example, the quality of many water purifiers with more than 10 filters on the market is very poor, because the more filtration stages, the smaller the water pressure and the greater the risk of water leakage. There are many filter elements with repeated filtration stages, and the annual maintenance cost is high. Some filter elements are just for display.
Seven, according to the purchase of water quality.
1, the water quality in different regions of China is different, so different water purification schemes should be selected in different regions, which is also of great significance to the water purification industry. 1, the hardness of water is different in different regions. The high-hardness water in limestone areas in the north and south of China is high in calcium and magnesium ions and easy to scale, so you should buy an advanced filtration water purifier with ion exchange resin filter element. The general matching model is: (pre-filtration) whole house water purifier (central water purifier)+water softener+water purifier+pipeline model number.
2. For urban tap water with heavy residual chlorine, abnormal color and odor and high organic content, you can choose a household water purifier with a large activated carbon load. Because activated carbon has a strong adsorption effect on residual chlorine and odor in water, it has obvious removal effect on organic matter. Pre-filtration+whole house water purifier (central water purifier)+kitchen water purifier+taste factor+pipeline machine: mode.
3. For the purification of tap water with turbid water quality in urban and rural areas, a household water purifier with dual functions of coarse filtration and fine filtration should be purchased. Pre-filtration+whole house water purifier+kitchen water purifier+taste factor+pipeline machine mode.
Eight, some basic principles of choosing a water purifier.
1, choose big brand manufacturers and after-sales enterprises with guaranteed quality.
2. It is normal that the water filtered by the ultrafiltration water purifier contains white suspended matter or floating objects. This is calcium hydroxide and magnesium hydroxide, which are components of calcium tablets and are beneficial to human body.
3. The water filtered by the pure water machine can be safer and more secure, and the minerals that the human body ingests from the water every day can be ignored. Some manufacturers are deceiving consumers by saying that pure water is unhealthy.
4. It is safer and more reliable to use pure water machine in areas with serious heavy metal pollution.
Some consumers think it is safe to use groundwater. In fact, groundwater is a seriously polluted water source, especially heavy metal pollution, which is invisible to the naked eye, extremely harmful and carcinogenic. More unsafe than surface water.
Myth 1: The more product filters, the better.
The more filters, the better. Some low-end water purification products are easy to be filtered by seven or eight grades, but they all use simple filtering materials, and the filtering effect may not be as strong as that of high-performance filter elements. Water purifiers without ultrafiltration membrane filtration, such as GPAN material or U-PVC material or RO membrane material, have no practical significance and effect.
Myth 2: Just look at the brand and don't consider professionalism.
When choosing a water purifier, you must choose a professional water purifier manufacturer. For example, the brand OWIN water purifier was founded 194 1 years ago, with a history of more than 70 years and more than 100 patents. In 20 14, the scale of China's participation in water purification exceeded 10000㎡. Aon is a big manufacturer in the field of water purification, and there is no one. Aon has successively managed household water purifiers, commercial water purifiers, engineering water purification equipment host production and testing plants, water purification pipe joint manufacturing plants, filter bottle filter element manufacturing plants, brand operation centers and OEM/ODM operation centers, with complete production facilities, which further accelerated the vertical integration operation process. International excellent technology and excellent quality make OWIN water purifier trusted by hundreds of millions of consumers around the world. Not only entered thousands of households, but also entered various domestic units, such as hotels, schools, hospitals, etc., to protect the health of more and more consumers, and even became a 20 14 special water purifier for China's border defense.
Myth 3: Different manufacturers have different materials, and activated carbon is out of date?
No, activated carbon is a good filtering and adsorption material in essence. Almost all water purifiers use activated carbon. If activated carbon is not used, no matter how high the filtration accuracy is, the taste of the effluent will be discounted. There are three kinds of activated carbon: granular, powdery and activated carbon rods. The first two are lower in cost, but often do not need filtration. The latter is a safer choice, which can achieve 100% complete filtering. However, different kinds of activated carbon have different point values and different effects. Generally, domestic activated carbon includes coconut shell carbon (point value: 900), fruit shell carbon (700) and coal-based carbon (300). Imported activated carbon: Calgon carbon (2000), Nuoli carbon (6000).
Myth 4: The filter element cannot be changed for a long time.
In fact, the filter element that will block is a good filter element, which also shows that the water purifier is really effective. However, water purifiers with reasonable product design and excellent quality will not be banned. The service life of the first generation water purifier is 3 months for PP cotton or activated carbon filter, 2 years for PVC and PAN filter, and 6 years for GPAN and U-PVC filter. It is often exaggerated in the market that there is no need to replace the filter element, so don't pursue low prices too much. At present, the water purifier is still the demand of people who pursue high-end quality of life in China. Generally speaking, the higher the price, the better the effect will be. In addition, the life of high-quality filter elements and the purified water will be relatively high, and the price is naturally determined by the value. So the overall calculation is very cost-effective, and health itself is priceless.
Myth 5: Ultrafiltration machine can't completely remove scale. Is it safe to drink water?
You can drink it safely. Scale can be divided into hard scale and soft scale. The main component of hard scale is calcium and magnesium compound, which is harmful to human body after long-term drinking. The main component of soft scale is calcium and magnesium ions (just the calcium tablets we eat every day are also calcium and magnesium ions), and moderate drinking is beneficial to the human body. The filtering accuracy of the ultrafiltration machine is 0.0 1 micron, which can filter out substances harmful to human body such as rust, sediment, virus, bacteria and heavy metals. Filter out the heavy metals in the water to prevent calcium and magnesium ions in the water from reacting with them to generate compounds (i.e. hard scales), which can be safely drunk.
