I want to know this too; waiting for a professional’s answer.
The effect is basically none. You can ask the seller about the water quality data; it will be clear from their response.
I don’t think it’s necessary; over time, it will still be a source of pollution
There are many manufacturers in this field these days; for example, the first is Midea, the second is Lisheng, the third is Qinyuan, the fourth is Quanlai, the fifth is Aimate, the sixth is Kaineng, the seventh is Angel, the eighth is Aipuote, and the ninth is Shenhua Water Pipe Expert

Working principle of the RO pure water machine: It undergoes five stages of filtration. The first stage of filtration uses melt-blown fiber filters to remove sand, rust, copper oxide, silt, phosphorus contaminants, and other impurities from the water. Second-stage filtration: Granular activated carbon filter element – removes unpleasant odors and the chemical taste of chlorides from tap water. Third-level filtration: Sintered activated carbon filter element – effectively adsorbs various odors and discolorations in water, thereby protecting the RO membrane. Fourth-level filtration: RO reverse osmosis membrane – filtration precision of 0.0001 microns; bacteria must be reduced in size by 4000 times to pass through, and viruses must be reduced in size by 200 times to pass through. It removes bacteria, heavy metals, salts, minerals, and other dissolved substances from water, as well as the chemicals added during tap water treatment. Fifth-level filtration: post-filter activated carbon – to adjust the taste of pure water and maintain its freshness.
Just buy any one. It is quite water-intensive, though. Generally, people buy Angel, Lintang Bird, and AO Smith. Most of them are domestically produced. Those with good hands-on skills can simply buy some accessories and install them themselves. The price should be kept under 1500.
Home water purification devices can be purchased at renovation stores like B&Q, with prices starting around 1,500 yuan or more. . .
It’s fine when it’s new, but after some time the water quality becomes very poor; colleagues who used it found that, several months later, its quality was even worse than that of tap water. If you contact the manufacturer, they will ask you to replace the filter element, which will cost several hundred dollars. Then you’ll use it as a decoration. The main post-maintenance operations are difficult to carry out.
