Passage of water or other solvents across a semipermeable membrane is part of a water purifier’s filtration mechanism. Dissolved solutes that pollute water are blocked by the membrane present in the filter. As a result, many different contaminants can be removed from the water, such as ions, pesticides, bacteria, and other compounds. Using a UV filter eliminates all germs in the water. On the other hand, the dead bacteria float to the water’s surface. An RO water purifier destroys germs and removes their floating corpses. As a result, RO water is more sanitary.

Test the water quality and examine its ability to eliminate specific contaminants before purchasing a water purifier. In addition to the cost of filter replacement and the amount of water your family consumes, you should consider the filter’s lifespan and the frequency of replacements.
