What are the main considerations for purchasing water purifiers?

For example, RO membrane reverse osmosis technology: the higher the filtration accuracy of the water purifier, the greater the relative wastewater rate. As the core part of the deep water purifier, the working process of RO membrane is actually a process of liquid concentration, so the proportion of water purification and wastewater of the general water purifier may reach 1:3, and the amount of wastewater is also 1:1.

Nutrients left in filtered water:
If it is the reverse osmosis principle, the filtered water is generally pure water
The higher the precision of the water purifier, the more thorough the filtration of water. When the harmful substances in the water are removed, the mineral elements beneficial to the human body are filtered. Therefore, we drink clean pure water after the water purifier, which can only supplement the water demand of people, but lack of mineral demand.
There are also claims on the market that pure water is not suitable for long-term drinking, but the impact is not significant. Now there are some mineral water purifiers on the market.
And the size of the fuselage,
Some of the smaller ones will not affect the beauty of the kitchen, and will not occupy a lot of space. But it depends on personal preference
Moreover, the problem of filter element replacement and cleaning
There are some filter elements that can be taken out and cleaned on a regular basis, which can generally detect the effect of water purification and guarantee the quality of water purification to a certain extent, but also need to be replaced on a regular basis. Another is not allowed to change, such as photon filter element. This also depends on everyone's situation, but I suggest that it's better to buy enough detachable products and clean them
