Which Is Better, Ultrafiltration Or Reverse Osmosis Water Purifier?
Dec 17, 2018

In many people's eyes, the water purifier is not used to filter water, the function should be similar. Ultrafiltration and reverse osmosis are commonly used household water purifiers. Their functions are different, which makes it difficult for many friends to choose water purifiers. What kind of water purifiers should they buy?


Firstly, from the functional point of view, the ultrafiltration machine is a water purifier that filters water through ultrafiltration membrane. It can well remove sediment, rust, bacteria, suspended matter, algae, macromolecule organic matter and other harmful substances in water, while retaining minerals and trace elements beneficial to human body. The water filtered by the ultrafiltration machine is similar to the mineral water in the market. On the basis of removing sediment, rust, bacteria, suspended matter, algae, macromolecule organic matter and other harmful substances, the device also filters out minerals and trace elements in water, which is equivalent to pure water on the market.


What is the principle? The core components of reverse osmosis and ultrafiltration are all filter elements. The main difference is that the pore size of reverse osmosis membrane is only 1/100 of that of ultrafiltration membrane. Therefore, reverse osmosis water purifier can remove heavy metals, pesticides, trichloromethane and other chemical pollutants in water. Ultrafiltration water purifier is powerless. Therefore, from the safety point of view, reverse osmosis water purifier filters more thoroughly, can meet the standard of direct drinking, so if conditions permit, you can choose reverse osmosis machine.


Is the reverse osmosis water purifier perfect? NO!

Reverse osmosis machines need pumps and consume electricity, so there are hidden dangers of electrical safety, and the reverse osmosis machines have many joints, high water pressure, complex structure and relatively expensive price. Relatively speaking, ultrafiltration machines do not need pumps, do not consume electricity, there will be no electrical safety problems, and fewer joints, low water pressure, simple structure and relatively affordable price. Therefore, if your tap water quality is good, the ultrafiltration machine can basically meet the daily needs. Of course, if the water quality is poor, the reverse osmosis machine is recommended.


With the improvement of people's living standards, there are higher requirements for water quality. Sometimes people want to drink pure water, sometimes they want to drink mineral water. What should I do? At present, there are many water purifiers with double membranes and double water on the market. A water purifier can produce both pure water and mineral water.
