EspañolWith the improvement of people's living standards, people are no longer satisfied with simple food and clothing, but pay more and more attention to the quality of life. At the same time, the harm caused by water pollution is closely related to human health. In order to drink healthy water, every household is already using water purifiers. It is understood that many users still prepare water purifiers when they buy water purifiers. I am troubled, so I walked into many misunderstandings, and various problems appeared after the purchase. Here, in order to allow users to more accurately purchase the most suitable water purifier, I will sort out the following water purifiers for everyone The misunderstanding of the purchase of a water purifier is only for reference for users who need to buy a water purifier, and I hope it can help users.
Misunderstanding 1: The filter element can not be replaced for a long time
In the process of using a household water purifier, the longer it is used, the longer the filter element will intercept harmful substances, which will cause more serious damage to the filter element’s blocking and functional degradation. However, some unscrupulous manufacturers deceive consumers under the pretext that they do not need to change the filter element. This kind of business does not only exaggerate, but also damages people's interests and health. If the filter element is not replaced for a long time, it is more harmful than tap water. Like people, they will continue to age.
Misunderstanding 2: The more filter elements of the water purifier, the better
Most consumers think that one more level of filtering will be more safe, but in fact, it should be more dangerous. The key to the water purifier is to look at the effect of filtration. There are many claims on the market: eight-stage filtration. The industry knows that the so-called eight-stage is nothing more than PP cotton, activated carbon, then PP cotton, then activated carbon... Repeated use, the effect How can you imagine. The most important thing is: the filter element of the water purifier must be replaced regularly. If the filter element is not replaced for a long time, the filter element will become inevitable. Multi-stage filtration makes the filter element easily contaminated by bacteria. In addition, it also adds difficulty to the after-sales service of the water purifier. How to replace which filter element scientifically after a period of use? If all are replaced, will the user agree? Therefore, the number of filtration stages is not the more the better, but the most important thing is to choose a reasonable purification product according to the water quality of your home area.
Misunderstanding 3: The higher the filtering accuracy, the better
Bacteria harmful to the human body in water such as Escherichia coli, cyst bacteria, etc., their volume is generally above 0.7 microns, while the volume of microorganisms and minerals that are beneficial to the human body is about 0.3 microns, so the higher the accuracy of the water purifier While processing the water quality, it also intercepts substances that are beneficial to the human body. Readers who have done a little research on water purification products should know that drinking pure water for a long time is harmful to the human body. Consumers should read more and compare how to choose a water purifier with appropriate accuracy. Detailed introductions of various products and working principles are necessary to understand in detail. Generally speaking, domestic RO reverse osmosis household water purifiers are equipped with PP cotton, granular activated carbon, sintered activated carbon, reverse osmosis RO membrane, and post activated carbon 5-stage filter element, which is the 5 continuous rows seen on the appearance. The filtration accuracy of the cartridge is generally claimed to be above 95%, which can filter out a lot of heavy metal ions. However, the ultrafiltration membrane used in the ultrafiltration water purifier has a much larger pore size than the reverse osmosis membrane, so the filtration accuracy is low, and it is incapable of metal ions.
Misunderstanding 4: The newer the technology, the better
Not long ago, I heard of a water purifier for mineralized water. It is said that it can add minerals needed by the human body into the water. Let alone whether adding minerals to the water is as convenient as adding sugar, even if it is added, whether the body can absorb it is still a question. If this causes other adverse effects, it is really not worth the gain. With new technologies and new products in other fields, you can be the first batch of people who eat crabs. However, for water purifiers that are closely related to the health of yourself and your family, you are responsible to your family by choosing reliable products that have been proven over time.
Misunderstanding 5: The more expensive the better
This is a typical buying misunderstanding. Many buyers think that the technology is too esoteric and troublesome, and they think: I don’t want to be cheap, I’m willing to pay for my health. I choose the most expensive one. Many merchants are targeting this point, using some new technologies as their selling points, and the price is a bit tricky. If you see that the price of a product is much higher than that of similar products, you have to carefully study where it is expensive. General household water purifiers are too cheap to buy, and too expensive have to wait and see.
Misunderstanding 6: Products with stainless steel enclosures are not necessarily good
Stainless steel shell products, must the quality be good? Is it safe? I don’t know that stainless steel is just the “coat” of the product itself. Most manufacturers using stainless steel shells use 301 and 302 stainless steel. 304 stainless steel is rare, let alone 306; that is, the product that everyone understands. Appearance, and in fact, the internal filtering devices of the current water purification products in the industry are actually plastic materials. This is an indisputable fact.
Misunderstanding 7: The longer the service life of the water purifier, the better
The longer the service life of the water purifier, the better. This is the wishful thinking of some manufacturers to provide consumers with wrong guidance. Many manufacturers are eager for quick success and short-sighted behavior, claiming how many years their water purifiers can last, but they don’t talk about the replacement of filter elements. This way, sales in a short period of time will increase, but in the long run, it is a kind of Unreasonable and unscientific methods are tantamount to killing chickens and taking eggs, and will ruin their own way for this.
