With the improvement of the quality of life, more and more families began to pay attention to the health of drinking water. The water purifier, as a major “magic weapon” to improve water quality, has gradually become a new favorite in the kitchen. But! The market is full of a variety of water purifier products, but let a person pick the eyes. In the end, how to avoid the pit of IQ tax? Today we will talk about the purchase of water purifier, as long as you recognize “this” key points, you can easily find a good machine for yourself!
What is a water purifier? What does it do? First of all, to clarify what is a water purifier, so that you can know what you buy is worth it! Simply put, a water purifier is a device that removes impurities and harmful substances (such as heavy metals, bacteria, viruses, etc.) from tap water through filtration technology, retaining only the clean, “pure” H₂O.
Many people may ask: “The family has the habit of boiling, still need to install?” The answer is: yes! Because boiling can only kill bacteria, but like heavy metals, pesticide residues, these inorganic pollutants will not be eliminated by high temperature. Want to drink really healthy and safe water, or have to rely on professional equipment!
Selection must be recognized - RO reverse osmosis cartridge If you want to say that the most important point can not be ignored when purchasing a water purifier, that is the RO reverse osmosis cartridge. Why is it so important? It has to start with its powerful filtration ability.
RO cartridge can be seen as the brain of the whole machine, it uses a kind of ultra-precision filtration membrane, pore size is only 0.0001 microns. This means that even a millionth of the size of the diameter of a hair strand will be blocked out! Heavy metals, bacteria, viruses, etc. are almost completely OUT, leaving only pure water that is clean to the core.
So, no matter how fancy you see a machine advertised, do not forget to carefully check whether it is really equipped with RO reverse osmosis filter. If it doesn't, then it's a waste of money even if it's cheap!
Why is there such a big price difference on the market? I believe that we have shopped on the e-commerce platform, will be confused about a phenomenon: why is the same called “water purifier”, the price is from a few hundred dollars to a few thousand dollars ranging? In fact, this mainly depends on the following aspects:
-Core component quality: good brands usually use imported or more durable RO membrane, while low-quality products may cut corners, with low-cost materials.
-Level filtration design: the mainstream on the market is a 5-stage filtration structure (including PP cotton, activated carbon, RO membrane, etc.), but some low-priced products may lack the necessary steps.
-After-sales service and the cost of changing the core: do not just focus on the machine itself is cheap, some brands later change the filter element is incredibly expensive, even more cost-effective than a new machine!
So don't just look at the price, but combine it with the configuration and long-term use costs.
How to quickly recognize reliable brands? In the face of a wide variety of emerging brands, what should we ordinary consumers do? In fact, it is very simple, look at three indicators will be enough:
1. Whether there are authoritative certificates such as the domestic health department issued by the water-related approvals and internationally recognized NSF certification, to a certain extent, to ensure that product quality standards.
2. Clearly the actual waste ratio (output / waste ratio) excellent products generally reach 1:1 or higher, while some low-quality products may waste more of the original tap water, not only environmentally friendly but also cost money!
3. user reputation and after-sales system perfect degree of real evaluation on the network is very important, while choosing those who support the national warranty, professional customer service team of the big brands, more peace of mind.
Small science and technology tips: how to determine whether your tap water needs to be installed? Not every household must install a full-featured water purifier. Before deciding to buy, you can first understand the local water supply, as well as your family's drinking needs:
-If the tap water in your city has high hardness (obvious scale) and a strong odor, then it is recommended to directly choose a model with RO function;
-If you just want to improve the taste, you can also consider other types, such as ultrafiltration or nanofiltration equipment;
-If you are not sure, you can buy a TDS pen (total dissolved solids detector), measure the value of tap water at home, higher than 300ppm basic recommendations for the installation Oh ~!
In the matter of purchasing water purifier, “recognize this” is crucial, that is, RO reverse osmosis technology. Regardless of how appealing the ad words, gimmick how cool, without it, your money will really become IQ tax. Of course, but also according to your budget and the actual needs of a reasonable choice of configuration, do not blindly follow the trend of the pursuit of expensive styles.
Finally, a reminder, now many well-known brands have promotional activities, such as the gift of the first year of free replacement of filter services and so on, you can pay more attention to the preferential information Oh ~ after all, who do not want to save and save money?
I hope that today's article can help you avoid the pit success, next time to bring you more practical knowledge of it ~!
