In the renovation of new houses, whether to install a water purifier is often a controversial topic. Some people are not worried about the hygiene of tap water, and for health reasons, they feel that water purifiers must be installed. But some people think that this is completely an IQ tax, our water is from qualified and compliant waterworks, and there is no problem with drinking it for so many years, and the water purifier is an IQ tax at all, and it is not worth it.
So, is there a need to install a water purifier? Is it an IQ tax exactly? In the face of a dazzling array of water purifier products on the market, some claim to be the best technology, and some claim to be patented products, how to choose the right one? Today, let's take a look at this issue together.
The water purifier itself is not an IQ tax, and an inflated water purifier is an IQ tax. Let's put it this way, the water purifier itself is not a high-tech product, and its existence can indeed optimize water quality, but the chaos in the water purifier market, exaggerated publicity and other problems have made many people who have not bought a water purifier question it, and even consumers who buy a water purifier for the first time may also realize that they are on the road after buying the product.
For example, some small brands of new water purifier manufacturers will put the label of foreign brands on their own water purifiers to pretend to be foreign brands, many consumers who do not know how to do it feel high when they hear it, and they are willing to pay five or six thousand to buy, in fact, the cost of the entire water purifier is two or three hundred yuan.
There are also some businesses that sell water purifiers that will take root in the community, specifically target the elderly, give them false promotional materials, and then lure the elderly to attend classes on the grounds of giving away water purifiers for free, spread rumors to exaggerate the disadvantages of drinking tap water directly, alarmist, and even do all kinds of small experiments to make them believe that the water quality at home is really bad, so as to further persuade them to spend a lot of money to buy their filter cartridges. This is also the reason why water purifier products have been so controversial for a long time.
Whether there is a need to install a water purifier depends on your water needs. If you have high requirements for water quality and want to filter floats, heavy metals, bacteria, viruses, residual chlorine, sediment, and rust in the water to drink healthier and cleaner water, a water purifier must be installed.
But if the family budget is limited, living in the city, there is no serious water pollution, you can also not install it, after all, the cost of consumables such as filter cartridge will be counted in the follow-up of the water purifier. It is enough to boil the water and drink it every day, and it usually does not cause health effects.
Look at the brandIn case you buy a water purifier with excessive heavy metals, not only can you not purify the water, but it will also have an impact on your health. Those like Qinyuan, Angel, and Smith who have a national joint insurance will be more assured.
Look at the way the water is filtered:The effect of water purifier filtration mainly depends on its filtration method, and when purchasing, it is recommended to choose a water purifier using RO reverse osmosis filtration technology. The filtration accuracy of the RO membrane is high, which can reach 00001 microns, 999% heavy metals and microorganisms, drinkable straight.
Like the ultrafiltration water purifier can not be reached, can not filter some heavy metals and calcium and magnesium ions, although there is no need to plug in, but the filtered water has to be boiled and then drink more securely.
The water purifier is not like other household appliances that are one-time input, its filter element is a consumable, ** must be asked in advance, it is best to have a universal filter element, so that the replacement cost is low.
Look at the rated water purification and water efficiency level:The water rating will vary depending on the filter. The lower the number, the more often the filter needs to be replaced, and therefore the more costly it will be. Generally speaking, level 1 water efficiency: water purification water yield is 65%, and the rated total water purification is 4000L;
Level 2 water efficiency: 55% of water production rate, 3000L of rated total water purification;
Level 3 water efficiency: water purification water yield is 45%, rated total water purification is 2000L;
The water purifiers on sale from July 1, 2022 are pasted with water efficiency labels, and the level 1 water efficiency represents the most water-saving. Therefore, as much as possible, choose Class 1 water efficiency products with high rated hydrostatic flow.
See the speed of the water:Water purifiers with slow water discharge speed often need to spend your time waiting for water there, so it is recommended to choose a water purifier with a flow rate of more than 3L min to ensure that the water output speed is faster. You can experience for yourself how long it takes to get a glass of water at the time of purchase.
In addition to the above points, it is necessary to look at the flux and wastewater ratio, but the most critical thing is **. In addition to the factor of brand premium, if some unknown water purifiers are sold for five or six thousand yuan, it is definitely an "IQ tax". Big brands are their own shells, the cost is higher, and the miscellaneous water purifiers are basically shells produced by foundries, OEM, as long as it is the same filter element, the filtration effect is actually the same. Finally, it is not suitable to drink filtered for a long time, because it does not contain the minerals needed by the human body, which will make the human body lack trace elements for a long time and cause sub-health problems.
