1, reverse osmosis pure water equipment: it can completely remove beneficial and harmful substances in water and produce pure water. Pressurized power supply is needed, and the utilization rate of water is low (there is more waste water and less pure water, which generally wastes about 50% of tap water). The purification cost is high and the flow rate is small, which only solves the problem of drinking water.
2. Activated carbon water purification equipment: it can eliminate different colors and odors in water, but it can't remove harmful substances such as bacteria in water, and the removal effect of sediment and rust is also very poor.
3.PP filter element pure water equipment: Single-cylinder water purifiers with various PP filter elements are generally low in price, but the filter elements are easily blocked and need to be replaced frequently, and the filtration accuracy is not high, so they can only be used for preliminary filtration of water.
4. Barreled purified water equipment: The barreled water purifier installed on the drinking machine generally adopts filtering materials such as activated carbon, ceramics, etc., which has low filtering accuracy, inconvenient cleaning, easy secondary pollution and small water volume, and only solves the problem of drinking water, but in fact, people who know filtering technology are afraid to drink.
5. Functional pure water equipment: There are many water machines in the market under the banner of health care function, such as ion water machines, spectrum water machines, magnetized, mineralized and activated water purifiers.
Which is better?
This needs to decide which one to use according to the needs of users, not which one is good.
