Water purification people teach you how to choose a suitable water purifier

In today's era of focusing on healthy living, the quality of water is directly related to our quality of life and health. Tap water may be affected by aging pipes, secondary pollution and other problems during the delivery process, which makes many families begin to consider installing water purifiers in the hope of obtaining purer and safer drinking water. However, in the face of a wide range of water purifier products on the market, a variety of complex parameters and functions, in the end, how to select a truly suitable for their family water purifier?

A survey shows that in the world's tap water, measured chemical pollutants are as many as 2221, some of which are recognized as carcinogens or carcinogens. From the tap water drinking standards, China is still at a low level, tap water can only be used to precipitation, filtration, chlorination and disinfection methods, river water or groundwater simply processed into potable water. Chlorination of tap water can effectively kill germs, but also produce more halogenated hydrocarbon compounds, the content of these chlorine-containing organics has increased exponentially, which is the biggest source of various gastrointestinal cancers in human beings. According to the latest information, China's major cities, only 23% of the residents of drinking water in line with health standards, small towns and rural drinking water qualification rate is even lower. With the improvement of living standards we care more and more about the quality of water at home, the installation of water purifiers in the renovation of not a few, especially at home with the elderly, children.

But in the face of the choice of water purifiers, many people are “lost”, can not buy the right product, for example; do not understand the technology, the pursuit of big brands, ignoring the after-sales service and so on! I also experienced a number of water purifiers to understand the problem of water purifiers, in order to let the people less detour before embarking on the water treatment industry. Today, we will talk about the water purifier seven do not buy.

Water purifier 7POINT do not buy

First, no brand, no certification of the “three no products” do not buy

Some low-priced water purifiers under the banner of “factory direct” “export single”, seems to be cost-effective, but hidden hidden dangers. These products often have no production qualifications, not through the national water-related approvals, and even the basic brand identity, after-sales contact information are not available. There is no quality assurance of the water purifier, not only the filtering effect is difficult to guarantee, but also due to the material does not meet the standard precipitation of harmful substances, long-term use of health hazards. Recognize ** “water-related approvals” is the key! Each regular water purifier needs to be tested by the national health department to obtain water-related approvals before they can be listed. Purchase can log on the “national disinfection products online record information service platform” **, enter the product name or manufacturer information to check the authenticity of the water purifier without approvals, and then don't touch the cheap!

Second, over-exaggerated features of the “black science and technology” do not buy
“three days in addition to limescale, seven days down three high” “filtered water cure all diseases” ... ... In the face of this kind of outrageous publicity, must remain awake. The core function of the water purifier is to filter impurities, heavy metals, bacteria and other harmful substances, can never be a substitute for medication. Remember, a water purifier is not a miracle cure-all! When choosing priority attention to filtration technology (such as reverse osmosis RO membrane, ultrafiltration membrane), cartridge materials and other core parameters, away from those with false concepts to harvest IQ tax products.

Third, the cartridge cost outrageous “consumables assassin” do not buy

Filter is the “heart” of the water purifier, but also the main cost of long-term use. Part of the brand to depress the machine's selling price, deliberately raise the price of the cartridge, and even the use of ** “bundled cartridge ”** (can only buy the original high-priced cartridge), resulting in the late maintenance costs far more than the water purifier itself. For example, a thousand-dollar water purifier, the annual filter replacement cost of up to 2,000 yuan, with 3 years of spending enough to buy a new machine! When choosing, be sure to ask about the type of cartridge, replacement cycle, unit price, calculate the cost of long-term use. It is recommended to choose a strong generality of the cartridge, price transparency of the product, or support ** “independent core” ** model, reduce the late expenditure.

Fourth, the flux is too small, the water is too slow “turtle speed machine” do not buy

flux (unit: G) determines the speed of the water purifier. Flux is too small water purifier, full of a cup of water to wait dozens of seconds, soup, cooking is more anxious to go round and round. For a family of 3-5, it is recommended to choose a model with a capacity of 600G and above, while a product with a capacity of 1000G or even 1200G will be faster in receiving water and provide a better experience in daily use. For small households or single-person use, choose 400G models, but be careful: water purifiers with too low a capacity may need to be paired with pressure buckets to store filtered water, and pressure buckets carry the risk of secondary contamination, so they are not the best choice.

Fifth, the water efficiency level is low, the waste water ratio is high, “water-consuming machine” do not buy

water purifier will produce a certain percentage of waste water, the higher the waste water ratio is more wasteful of water resources. According to the national standard, the water efficiency level is divided into 1-5 levels, 1 level of the most water-saving (water production rate ≥ 65%), 5 levels of the most water-consuming (water production rate ≤ 35%). When purchasing, recognize the 1 - 2 level water efficiency products, not only environmental protection, but also can save water expenses. Some of the old reverse osmosis water purifier wastewater ratio as high as 1:3 (i.e., filtering 1 cup of pure water to produce 3 cups of wastewater), long-term use is very uneconomical. The new water-saving technology (such as dual-water design, zero-aged water technology) can reduce the wastewater ratio to 1:1 or even higher, the purchase of priority consideration of such models.

Six, installation and maintenance of complex “toss machine” do not buy

For families who have been renovated, the installation of water purifiers should try to avoid destroying cabinets, pipes. Part of the water purifier requires professional drilling, change the water and electricity, installation difficulty, high cost; there are also some products cartridge replacement steps are cumbersome, you must make an appointment with the after-sales service door to door operation, the use of the experience greatly reduced. It is recommended to choose free installation, plug-and-play desktop water purifier, or support ** “independent core” under the kitchen model. For example, some brands have designed a magnetic filter **, bare hands 3 seconds to complete the replacement, saving time and money.

Seven, after-sales no guarantee of “orphaned machine” do not buy

water purifier needs regular replacement of filter elements, maintenance, after-sales can not keep up, the machine is easy to become “ornamental”. Some small brands or e-commerce platform “net red models”, sales are hot but very few after-sales outlets, no one to repair after the failure, the filter element is nowhere to buy, and ultimately can only be abandoned. Priority is given to large brands, national warranty products, such as the United States, Haier, Qinyuan and other veteran manufacturers, not only the quality of products is reliable, but also provide door-to-door installation, regular maintenance, cartridge reminders and other services. When purchasing, confirm whether the local after-sales outlets, or support online fast repair, to ensure the use of worry-free.

Summarize

Selecting a water purifier is like choosing a “family health guard”, never figure cheap, greedy gimmick. Keep in mind ** “7 do not buy” principle **, from the brand qualification, core technology, cost of use, after-sales protection and other multi-dimensional comprehensive consideration, in order to buy a good product that really suits you.
