Stop fetishizing RO membranes! How should we choose a water purifier?

Have you noticed that more and more friends around you are discussing water purifiers, some say that the home tap water tastes strange, some are worried about the baby's milk powder water is not clean, and some directly by the word “RO membrane” this few words bluffed, think that it is equal to have peace of mind to drink pure water. In fact, if you think so, then you really have to be careful not to step on the pit! Today we will talk about what is RO membrane, it is not a panacea? Buy water dispenser and what hidden doorway worth paying attention to? After reading this article, I believe you will spend less money, choose a really good water purifier for your home.

Talk about RO membrane before, we have to first understand the market common several ways to purify water, in fact, the simplest kind of activated carbon cartridge called, this goods mainly rely on the adsorption of odors and impurities, large particles of sediment, rust is more effective, but to say that the bacteria and heavy metals, it is basically impotent; and then there is ultrafiltration technology, can stop most bacteria, but like viruses and dissolved heavy metals, such as a small volume of pollutants, it is still difficult to escape the clutches. The clutches of the devil. At this time we often hear the “reverse osmosis” (also known as RO membrane) to shine. In layman's terms, this thing has a very small pore size, only allows water molecules to pass through, most of the impurities can be blocked, so theoretically out of the high purity of pure water, used to make tea, cooking, or to the baby milk are no pressure. So it sounds, is not think RO membrane equal to everything?

In fact, the so-called “high-tech”, everything has its limitations. For example, RO membrane is indeed powerful, but it also has its own shortcomings - filtering too thoroughly, the calcium and magnesium minerals are all removed. Some people are accustomed to drinking spring or well water, and then suddenly switch to “soft” pure RO direct drinking, may feel taste astringent, and long-term zero mineral element drinking health, there is still controversy. Therefore, different areas of different family needs are quite different, some people like sweet taste, will tend to bring the right amount of mineral residues that type of ultrafiltration / nanofiltration products; and some newborn families or immunity weaker people, more concerned about the safety of non-polluting, that gives priority to RO.

# How to determine whether the home needs to install RO machine #] Here to teach you a simple judgment method, if the city tap water itself is up to standard and taste good, at the same time there are no special populations (such as pregnant women, infants and young children), ordinary ultrafiltration is enough to use. If the local water supply is usually turbid, heavy odor, or home health requirements are particularly high, you can consider upgrading to a water purifier containing RO reverse osmosis technology. But always remember, there is no one option that works for everyone!

Then say that many friends are easy to ignore some of the “small details”. For example, many people think to buy a more expensive big brand machine on everything, in fact, the real impact of the daily experience of the key, is the cost of maintenance and after-sales service. Some imported brands of consumables are very high prices, once a year to replace the calculation is far more expensive than the machine itself; while some national brands, although initially cheaper, but the subsequent replacement cycle is short, maintenance trouble, will also make people crazy. So it is recommended that you pick before you make sure to ask about the frequency of filter replacement, price and after-sales response time. If you have the conditions, it is best to choose to support the independent replacement design - this is not only to save money and convenient, only a few minutes to do it yourself, more reliable than honestly waiting for the master to come to the door!

In addition to the cartridge issue, you must also consider the actual speed of water and waste ratio. Some people have a small family, only two pots of boiling water a day, then the small flow rate of slow is not a big deal. But if the kitchen is busy all year round, a cooking to fill the pot, then meet those “one hour only out of a pot” slow model, you will doubt life ...... In addition, many of the early low-end products to deal with 1 liter of pure at the same time discharged 2-3 liters of wastewater, if a long time a lot of use, not only a waste of resources but also pull up the cost of living. Use, not only waste of resources but also pull up the cost of living. Therefore, the mainstream products are now generally publicized low waste ratio, such as 1:1 or even 0.5:1, is an effort to reduce waste, so that environmental protection and economic coexistence.

Speaking of this, I believe that many friends already have some inner spectrum. But there are many functions on the market, such as intelligent display, water quality TDS numerical monitoring, automatic rinsing and other black technology, looks dazzling, in the end there is no need for it? In fact, these intelligent features belong to the icing on the cake type, for usually too lazy to remember the maintenance cycle or the pursuit of digital life of the crowd more friendly. For example, TDS monitoring can help you understand in real time in and out of the level of cleanliness changes; automatic flushing can extend the life of core components. However, if you have a limited budget and spend your money mainly on the core filtration system and reliable brand after-sales service, these extra features can be taken as a reference item, not a must-have.

Remind consumers, now the network platform is a serious phenomenon of counterfeiting, try to recognize the formal channels in the purchase, do not easily believe the excessive touting ads. At the same time, you can check the authoritative test report before purchasing, to see whether it is approved by the national health license, which is also an important criterion for identifying the advantages and disadvantages!

Written here, you are not beginning to rethink their original mind “myth”? In fact, no matter which type of purifier, there is no absolute sense of the “strongest”, only fit their own needs will not fall into the trap set by the business. In the aftermath of the epidemic, people are paying more and more attention to healthy eating, and clean and safe drinking water is one of the tips to enhance the sense of well-being. If you plan to buy a reliable device for your home, you may want to clarify the daily use, the composition of the population and the subsequent maintenance budget, and then combined with the above dimensions of comparison shopping, ask a question, take a look at more, you will always be able to pick the one that suits your needs.

Finally, I would like to give you a tip: “Don't be fooled by gimmicks, pay more attention to the real experience.” I hope that every family can enjoy a good level of peace and prosperity!
