As a salesman who has been selling water purifiers for nearly 5 years, I have to say that the water purifier industry is chaotic;
If you want to buy a water purifier that suits you, please read and think about this short article carefully:
You may not have thought about it: is there a problem for water purifier manufacturers to produce water purifiers of the same brand, different models and different prices?
Have you ever thought: If the low-priced model (so-called three-stage) water purifier produced by a factory can meet the water purification requirements?
If you can?
So is it necessary to produce high-priced models (so-called class 5 or class 8) for water purifiers?
And much more expensive?
But: if the high-priced water purifier can really meet the water purification standard?
So selling low-priced models of water purifiers is not deceiving customers?
In order to adapt to the market, is the enterprise that sells regardless of whether the quality is up to standard trustworthy? It may be said that our low-end products have actually reached the standard, and the high-end products are just more perfect in function (nonsense, in fact, he is telling you that it doesn't matter whether you use them or not, and tap water is used only after reaching the standard)
So: when buying a water purifier, the price is not important, and the brand is not important. The only thing that matters is the effect!
How to choose an economical and efficient water purifier? You can refer to the following important indicators to buy:
1. Look at the filter element: the core component of the water purifier, and its quality directly affects the purification index of the water purifier.
First of all-pay attention to whether the filter element can filter impurities and make the water look clearer (it can be said that any water purifier can do it, but different filtering methods have completely different effects)
Filtration membrane: the market is also full of various brand-name filtration membranes, pp cotton and so on; In fact, the function is only to filter impurities above a certain specification.
Reverse osmosis: the most common in the market, and the filtration rate of 99% has become its biggest selling point; The disadvantage is also obvious that it is too clean (there are no minerals beneficial to the human body; And cannot filter microorganisms such as bacteria and viruses).
Secondly, pay attention to whether the filter element can filter odor and improve the taste (any water purifier with activated carbon can, but the filter element has different structural effects, different service life and different prices).
Granular activated carbon filter element: odor can be removed in a short time, but after a long time, it will be washed out of the waterway by water and lose the filtering effect; Disadvantages: the service life is uncertain (users will only know if the filter element has lost its purification ability)
High density activated carbon: long service life; Block structure, will not form a waterway; Disadvantages: Due to patent protection (high production cost), the production is complicated and expensive (it is 100 times higher than granular activated carbon with the same weight).
Finally-pay attention to whether the water purifier can kill microorganisms. Viruses and bacteria in microorganisms are potential pathogens and must be removed (general products can't kill microorganisms; Some products can kill microorganisms, but technology determines the risk of purification)
Chemical sterilization: kill microorganisms with chemical filters; Disadvantages: chemical residue, affecting taste and health (treatment: after installing chemical filter, improve the taste of ion filter or activated carbon filter; So that consumers can't directly detect the abnormality from the taste, which improves the difficulty of identifying chemical residues)
Ultraviolet sterilization; The sterilization rate is as high as 99%; Disadvantages: need to be charged (potential leakage safety hazard; Of course, the wireless transmission technology of electric energy can avoid potential risks), but this technology is protected by patent (high production cost)
A qualified water purifier can filter impurities, retain minerals beneficial to human body and improve the taste of drinking water.
A high-quality water purifier must: filter impurities, retain minerals beneficial to human body, filter various chemical pollutants, improve the taste of drinking water, and kill bacteria and viruses at the same time.
2. Look at the installation: Whether the water purifier is convenient to install directly affects your future use (is it convenient to move? Can I install it myself? The simpler the installation, the more convenient the maintenance)
Avoid-most of the pipeline replacement is under the stage, so it will be very inconvenient when the filter element needs to be replaced.
(For example, reverse osmosis needs to install a booster valve, and the pipeline must be replaced, so it requires professionals to install it at home, which is very troublesome and has potential safety hazards for personnel to enter and leave)
(For example, for low-end machines, it is also necessary to replace the pipes and install additional purified water outlet pipes, and it is also necessary for professionals to install them at home. )
Best- There is no need to replace pipes, wall-mounted or desktop water purification devices, and the installation and replacement are very convenient.
(For example, the water purifier of Yizhiyuan uses a diverter valve. Just connect the diverter valve to the faucet, and pure water and tap water can be used separately, which is convenient to install).
3. Look at consumption: wastewater-the water purifier using reverse osmosis technology will produce wastewater in the process of water purification, and the heavy metal elements in wastewater often exceed the standard by several times or ten times, so washing clothes with discharged wastewater will make clothes hard; Used to mop the floor, the floor tiles are damaged; Even flushing the toilet is not allowed, which will corrode ceramics; Washing vegetables is even more impossible; Therefore, the production of waste water greatly increases the use cost.
The proportion of wastewater directly affects the consumption of water purifier. The ratio of waste water produced by low-end water purifiers is as high as 1:6 (purifying 1 ton of drinking water requires 6 tons of water; 1 ton of tap water uses 3 yuan money, so it costs 1 ton of direct drinking water.
Some mature enterprises can reduce the waste water consumption to 1:3 (that is, drinking 1 ton of direct drinking water requires 9 yuan).
For water purifiers that do not use extreme technologies such as reverse osmosis, no wastewater will be generated during the water purification process, which greatly saves the purification cost.
Filter element-the filter element will be polluted by harmful substances such as impurities during the purification process of the water purification device, and it needs to be replaced regularly.
Water purifiers with several common filtration technologies in the market: generally, the impurity filter element, pp cotton and activated carbon filter element are replaced every 3 months; Replace the reverse osmosis filter element in 6 months; Price150-800 yuan. If the filter element is replaced on time within one year, it will cost about 100 yuan *3 filter elements *4 times +800 yuan *2 times = 2,800 yuan; In fact, the cost of the filter is far more than that, but many people just want to replace it on time)
High-end water purifiers only use the filter element once a year (the filter element is integrated), and the cost is about 1500.
4. Easy to see: Whether the water purifier is convenient in use is also an important indicator to determine the quality of a water purifier.
Replacement-Whether it is convenient to replace the filter element.
Some inferior or low-end water purifiers boast that their water purifiers do not need to replace the filter element in order to make people feel convenient and save trouble; There is a problem. Where are the filtered impurities?
So they made it up: magnetization?
Magnetization: refers to the process of obtaining magnetism from substances that are not magnetic.
Instead of what some salespeople say: consciousness is melted by magnetism!
Let ordinary water pass through a magnetic field with a certain intensity at a certain speed along the direction perpendicular to the magnetic field lines, and ordinary water will become magnetized water. They boast that they can purify this. Where is the improvement? However, magnetized water can completely lose its magnetic force only by leaving the magnetizing device for 30 seconds, and the effect can be imagined.
Cleaning: Not long ago, I heard some salespeople say that the filter element of a brand water purifier does not need to be replaced. As for cleaning once every 7 days, it can be used for 20 years (cleaning once every 7 days, 4 times a month, 48 times a year! 960 cleanings in 20 years)
It is also a miracle to persist (so, how much can it cost to clean each time) (if you forget to clean the clean water you drink? ) I admire them for playing so well!
It is often complicated to replace the filter element in the water purification device on the market (if it is a 5-level purification device, replace the filter element every 3 months and 6 months, with 5 filter elements at a time; 3 filter *4 quarters +2 filter *2 half a year = 14 times; Once a month on average) and for the average family, it needs professional on-site installation (14 on-site service, which may result in 14 service charge! )
High-end water purifier adopts filter element, which can easily replace the whole filter element by itself, which is convenient and time-saving.
Recoil: There is also a ridiculous design (recoil) on the market. It is said that the filter element will not be changed for 20 years. I bought that man just to see what backwashing is.
Water enters from the inlet, filters out impurities with larger particles through the coarse screen, and then reaches the fine screen. In the process of filtration, the fine screen gradually accumulates dirt and impurities in the water, forming a filter impurity layer, because the impurity layer is accumulated on the outside of the fine screen.
1for backwashing it-that is, tap water is connected to a fine filter screen, and water is filtered from the inside out (how terrible! For impurities and bacteria that have been adsorbed, it is said that these harmful substances can be washed away by water alone, but the internal reaction will attach a lot of impurities to the inner wall of the filter element of the water purifier, so that when the water is filtered in, these harmful substances will be mixed into the purified water to cause secondary pollution, which will not play a role in purifying water at all)
No.2 backwashing-because the impurity layer accumulates outside the fine mesh, a pressure difference is formed inside and outside the fine mesh. When the pressure difference of the filter reaches the preset value, the automatic cleaning process will begin, during which the supply of clean water is cut off and the cleaning valve is opened. Tap water does not pass through the fine filter screen of the filter element, but enters the sewage pipe to form a drainage flow, and the filter screen is washed with stored filtered water and tap water through the pressure difference inside and outside the filter screen. The pollution of the inner wall of the filter element is skillfully avoided. There are two kinds of automatic and manual)
By discharging waste water, it gives people the illusion that the filter element is clean. Why is it illusion? First of all, this method can only be used on the filter screen, but it will increase the consumption of activated carbon filter (activated carbon filter: the maximum service life of particle filter is 6 months, and it must be replaced 1 year). In fact, such constant backwashing of the filter will also consume the life of the filter.
In addition, many bacteria and germs can resist high temperature and fungicides, not to mention being washed with water.
So I suggest that you'd better buy a product to replace the filter, but it's hard to find such a door-to-door service now, and many of them are not free. You can choose to replace the water purifier with a filter element, so you can easily replace it. Just take out the filter cartridge and replace it. This is the safest and healthier way, and you can change it yourself without looking for someone else.
Tip-when to replace the filter element is also one of the advantages of high-end products.
Low-end products will not prompt the service life of the filter element, and it depends on the user's own estimation or replacement according to the instructions (in this way, even if the filter element fails, it will not meet the purification requirements or even become waste water, and the user will not know to drink it as usual; How terrible! Heavy metals and pollutants accumulated for several months were inadvertently drunk by you)
High-end products provide template indicator light to remind users whether the filter element needs to be replaced.
Convenience-different technologies will also bring different experiences when used (for example, some products need to be turned on, powered off and turned off, and calls must be restarted, but after a long time, customers can't find the book and forget which button to restart? You said trouble! This will not happen to high-end products, and incoming calls can be used normally without restarting. Is it convenient)
5. Look at word of mouth: Through the above understanding, you should have a very clear understanding of the purchase of water purifiers. Therefore, any water purifier that says that there is no need to replace the filter element is fooling you. If you don't believe me, let him read the instruction manual, which will definitely indicate the replacement time of the filter element. For an untrustworthy company, the product quality will not be so good!
6. Look at technology: the technology here refers to world-class patents (not everyone in the market can use it, everyone is using it).
Protection period of patented technology: 20 years for invention patents, and 10 year for utility model patents and designs from the date of application. During the period, others have no right to use it. If the protection expires, they can apply to the patent applicant or unit for authorization and pay the fee (it will be the technology used by everyone in about 30 years, and it will be free at this time). So the technology that everyone is using in the market can be regarded as outdated technology.
7. Look at the sales volume: A good salesman will give you a detailed introduction of the water purifier he sells, as well as the comparison with other similar products, the advantages and disadvantages of various devices, instead of blindly advocating his own products.
8. Look at after-sales: A good brand has a perfect after-sales system (however, this often requires the real purchase of products, and the use problem can only be realized if you are satisfied)
Not much to say here. If you need a water purifier, you can click on the blue word at the bottom of the answer and contact me in the first row of Amway solver's private letter.
How about buying Qinyuan water purifier filter in Taobao? And the security code query. Is it true? It's hard to say whether it's true or not. What is the security password?
Have you checked the security code? If it is a code anti-counterfeiting query, it is not guaranteed to be true. Because code anti-counterfeiting is no longer anti-counterfeiting, it is easy to be copied, and some people recycle anti-counterfeiting codes and paste them on fakes.
Why does Jumei clio have no security code? I heard that Jumei is really mixed with the fake. My friend didn't believe me and bought something specially. After comparison, it was found to be false. . .
You can doubt whether it is true.
Hope to adopt
Why does Midea Water Purifier need to replace the filter element? There will be a large flow of pure water when you use it for the first time, but the water volume will decrease after a long time.

How to check the security code of Tianzhilan water purifier? The water purifier, also known as the water purifier, originated from 1832 cholera in London, England, and was invented by Reed Stewart in England. Its water purifier can be divided into RO reverse osmosis water purifier, ultrafiltration membrane water purifier, energy water purifier and ceramic water purifier. The RO reverse osmosis water purifier comes standard with five stages of filtration, namely: PP cotton, granular carbon, compressed carbon, RO reverse osmosis membrane and post-activated carbon; Ultrafiltration water purifier is mainly ultrafiltration membrane, supplemented by other filter elements such as activated carbon (excluding energy filter element). Ultrafiltration water purifiers are divided into vertical and horizontal types according to installation methods. The vertical ultrafiltration water purifier consists of PP cotton, granular activated carbon, compressed activated carbon, external pressure ultrafiltration membrane and T33. The horizontal ultrafiltration water purifier consists of stainless steel shell, internal pressure ultrafiltration membrane and KDF. Water purifiers are mainly divided into household water purifiers and commercial water purifiers.
