What do you mean by good?
Water purification capacity? What is the size? How long does it last? How much does it cost to replace a filter? Or something else?
If it is cost-effective, I personally feel that using a water purifier is not a very suitable decision.

The tap water for daily drinking has undergone a variety of cleaning, sterilization and disinfection methods, and can meet national health standards through factory water quality testing, and then flows into thousands of households through long pipelines and secondary pressurized water tanks. Before entering the households, the long pipes passed through difficult terrain and roads, some pipes were in disrepair, some water pipes crossed with sewage pipes, and some water pipes in the building even had to pass through the toilet before reaching the kitchen. Because the leakage around the water pipe and the secondary pressurized water tank are rarely cleaned and disinfected, the water tank cannot be spotless, and many reasons such as rust in the water pipe will cause secondary pollution to the water quality.
Long-term consumption may become the cause of stones, cardiovascular, arteriosclerosis and other diseases. People have always believed that it is safe to drink as long as it is boiled, but in fact, boiled water just does not cause diarrhea, and the process of boiling water cannot remove those impurities in the water that can cause chronic diseases, so it can be said that the water we have been drinking for a long time is not very hygienic. The water purifier is a kind of pure water produced by filtering the raw water (physical method) without adding any compounds through the current international popular reverse osmosis and other methods.

In terms of function, there are water purifiers, water softeners, water ionizers, ultrafiltration machines, reverse osmosis and so on. Sounds complicated. There are a few things to pay attention to when choosing a water purifier:
2.After-sales service. This is very important because the water machine must replace the filter element to work.
It depends on whether the brand you choose has a perfect after-sales service system for slippery oak. (My uncle's family installed the water purifier a few years ago, because that manufacturer doesn't produce that model now, so I can't replace the filter element, so I can only make do with it).
3.At present, there is no perfect water purifier on the market that can solve all the problems of water information and grinding. Some can't solve the problem of water swimming scale, some need electricity, and some waste water.
This is quite normal, and it is important to put this into perspective. Bona's brand of water purifier is from Zibo, and his water purifier has several advantages, 1Ceramic membrane filtration.
Most of the water machine filtration uses PP cotton, which has to be replaced after a few months, while the ceramic membrane can be cleaned and used repeatedly. Moreover, the filtration accuracy is moderate, the filtration effect is good, and there is no electricity.

Very good, tap water is not very clean, there is the possibility of secondary pollution, bottled water is expensive, bottled water is also very expensive, inconvenient, there is also secondary pollution, easy to expire. For example, Anzhiyuan water purifier has high filtration accuracy, which solves the safety of drinking water from the terminal and can be drunk at any time. Whether it is good or not is unquestionable.

The purpose of the water purifier is to remove toxic substances such as sediment, rust, bacteria, heavy metals, and organic matter in the water, while retaining the minerals and trace elements in the water that are beneficial to the human body. At present, the principle of water purification is different, the process is different, and the water purifier is very cheap, but don't buy it, drinking it for a long time is not good for the body. Coal filter water purifier as much as possible to buy big brands, some small workshops out of the quality is not guaranteed, under normal circumstances, 2500 yuan below the water purifier has a variety of potential problems, either buy more than 2500 yuan, or rather not buy.
At present, the best brands sold are 3M, Aihuipu, Pais, Dalton, Qinyuan, and Lisheng, but Qinyuan and Lisheng are pure water machines, and Aihuipu is relatively low-end.

In other words, your question is a little wrong, the purpose of the water purifier is to purify water, of course, it is good for the human body. The outermost dense material such as ceramics filters large particles, and the inside uses tourmaline and activated carbon to absorb chemicals in the water. It is recommended that you must buy a water purifier with more activated carbon when you buy it, because activated carbon with large rice grains has a large surface area and can absorb odors, chemical molecules, etc.
Therefore, even high-end water purifiers have a lot of activated carbon in them.

The water purifier is the filter, if the harmful substances in the water are not filtered by the water purifier, then it is your kidneys that filter impurities, and the organs will age in advance, and the impurities will accumulate and then easily form stones in the body. Therefore, water purifiers are beneficial to the human body.
