Useful, of course useful. For example, Liyang, Kelingshui, these two brands are good. I'm not selling water purifiers, I'm not advertising them.
I have done experiments on these two brands of water purifiers, including pressure resistance and filtration capacity. Of course, the faucet water purifier is also insufficient, that is, the filter element is replaced frequently, generally 3 to 4 months, and half a year. For more than half a year, no manufacturer dares to give you a guarantee, don't look at them are very good.
If you live in a big city, it is enough to use a water purifier with a filtration capacity of 0 1 to 0 4. The water source in big cities is filtered by water purification plants, and the mineral content is not as high as that in inland mountainous areas, so it is mainly filtered sand and gravel, bacteria and chloroform, carbon tetrachloride, one type of water. Generally, bacteria are 0 2 to 3 microns in size, and the filter element is 0 4 can also be filtered out, because activated carbon is not a layer of paper and will go through many 0 1 to 0 4 channels, so there is no need to worry.
Recently, there have been many reports about unqualified imported water purifiers. In fact, don't worry, the ones who are blown up are all big enterprises, if none of these work, can a small workshop do it? Personally, I do not recommend the use of water purifiers, especially for children and the elderly, as frequent use will cause users to suffer from calcium deficiency and other mineral deficiencies.
At the same time, the water purifier wastes a lot of water, which I don't agree with. Every brand manufacturer has water purifiers and water purifiers, and it is better to choose after careful consideration.

The faucet water purifier can usually only filter large particles of impurities, and the filter cotton area is small, so the time to replace the filter element is shorter, but it is easy to install, and the observation is intuitive, and you can see whether the filter is dirty at any time.

At present, there are not many brands specializing in faucet water purifiers, and the more famous one is Damai water purifier.

The ranking of household water purifiers is all business behavior, and I think that household water purifiers mainly look at the function. In the countryside, you can choose an ultrafiltration machine, which mainly filters small insects and parasites in sediment and water to retain minerals. However, in areas with hard water, it is recommended to use a RO water purifier.
It can reduce calcium carbonate, commonly known as limescale.
The upstairs in the city is all tap water, it is recommended to use a ** pre-filter to filter rust or something, and then the kitchen is installing an ultrafiltration machine, I think it is enough. A magnetizer can also be installed in a bathroom with better conditions, and bathing and washing your face can beautify**.
The larger brands are 3M, Qinyuan, and Haiermei, which are also produced. Abroad it's Smith and Honeywell. The production base is basically in Shenzhen, mainly depending on their own conditions, I think ordinary families are ordinary brands.
My home is an ultrafiltration machine that was installed free of charge by an insurance company.
Finally, the most important thing is to look at the filter element, the ultrafiltration filter element must be the mainstream of the market, the new popular is the RO filter membrane of aviation technology, it is said that astronauts use it in the sky, recycling water.
If it helps, please.

1. If the amount of water flowing out of the faucet is small, it means that there are debris on the filter screen of the faucet outlet, which is mostly caused by the accumulation of scale.
