Water purifier is a common early filtering equipment in our life. It uses physical and chemical methods to realize the non-function of filtration, because there are a lot of chlorine, rust and some organic wastewater in urban tap water, which need to be filtered before drinking. The water purifier needs to be pressurized by household appliances, that is to say, it needs to be plugged in like a water dispenser to be used normally, and the filtering effect is really better. Because it adopts reverse osmosis, Al membrane and other corresponding filtration technologies, the filtered water can be directly drunk, which can meet the standard of drinking water, but its cost is relatively high and the filtration efficiency is limited.
Ultrafiltration machine is a way that can be used normally without the pressure of household appliances. It only uses the method of physical filtration to filter out some filter substances and organic residues in water. There is no need to plug in, and the filtration efficiency will be high in normal work. This kind of water can be directly used to wash vegetables and cook, but the effect of drinking it directly is not particularly good, and it has no effect in the short term. However, from the health point of view, it is not recommended to drink the water directly from the ultrafiltration machine.
There are also some differences in price between the two. Ultrafiltration is cheaper than pure water machine, and the cost will be much higher because of the corresponding electronic processing technology, so the price is relatively high, and it needs to be plugged in all the time to work normally. Therefore, from a practical point of view, it is completely possible to install an ultrafiltration machine in the kitchen.
