However, there are some drawbacks to RO purifiers.

UF is one of the processes by which some of the best water purifiers work in India. Like RO, it also uses a semi-permeable membrane to eliminate impurities from the water. It has a membrane with a pore size of 0.01 microns. However, due to the larger pore membrane, it cannot reduce the hardness of the water.

This high-end water purifier can run without electricity as the water passes using the natural force of gravity. The external water pump doesn’t hold water; therefore, there is no wastage. Water purifier brands that work on the principle of UF include Kent, LG RO UV UF, Aquaguard, Havells, etc.
