Water pollution problems become more and more serious day by day, and water purifiers are becoming more and more frequent in the lives of ordinary consumers. There are various kinds of water purifiers on the market. Not only that, but there is no difference in connectivity and non-energization. Is the water device good for buying and plugging, or is it not plugged in?
First of all, we need to understand the difference between plugged in and unplugged water purifiers.
Plug-in water purifier is what we often call "pure water machine" or RO reverse osmosis water purifier, its filtration accuracy is about 0.0001 micron, almost all the harmful substances in tap water can be filtered out, such as heavy metal. , viruses, fluorescent substances, pesticide residues can be eliminated.
It is an ordinary water purifier that is not plugged in, and is generally an ultrafilter. Its filtration accuracy is about 0.01 micron, and it is necessary to filter harmful substances such as bacteria, rust, colloid, sediment, suspended matter, and macromolecular organic matter.
From this we can also see that the RO reverse osmosis water purifier is generally suitable for places with poor water quality environment. It can deeply filter harmful substances in water and provide us with a safe drinking water environment. The ultrafiltration machine is suitable for use in places with good water quality, because its filtration accuracy is not very high, so even in a place with good water quality, the filtered water needs to be boiled and then consumed.
Which of the two is better for plugging in and unplugging? Let's summarize their advantages and disadvantages:
Advantages of pure water machine: The filtration precision is high enough to filter out harmful substances in the water and improve the taste and smell of water. Disadvantages: Because it is attached to electricity, it can not be used after power failure; the filter has a short service life, and the filter replacement cycle is short and the maintenance cost is relatively high.
The advantages of the ultrafiltration machine: no need to use electricity, can be used at any time, and will not produce waste water, the filtration amount is relatively large, the filter core has a long service life, and the maintenance cost is low in the later stage. Disadvantages: The filtration accuracy is not high enough, and the filtered water needs to be boiled and then consumed.
Found out, in fact, the two are complementary, may be an advantage in you, but what I embodied is a disadvantage.
