The difference is still quite amazing. Water purifier or water purifier is a general term. If the water purifier is refined, it can be divided into single-stage ultrafiltration water purifier, such as Vantage's Li Sheng Spring, which has a stainless steel shell and contains ultrafiltration membrane, and can also be called water purifier or water purifier. There are also classified filtration generally divided into four or five stages or more, mostly PP cotton, activated carbon, granular carbon, powdered carbon, ultra-filter element and post-carbon. The biggest difference is that these so-called water purifiers or water purifiers do not need power supply, and the filtration accuracy is mostly above one thousandth of a micron.

The difference between a water purifier and a water purifier is that it needs electricity (mostly) and has a vacuum water storage tank. The water purifier contains the functions and materials of the water purifier, and the filtration rate can reach one tenth of a micron. The most important thing is that it uses RO reverse osmosis technology, and because the filtration is finer, the general water pressure cannot pass smoothly, so electricity is needed. Electricity needs to drive the booster pump worn by the machine to suppress the raw water before it can pass. In fact, many bacterial viruses can only be completely filtered by pure water machine. This is just some basic common sense.
