Research is the base of all innovations and inventions. The development of water purifiers involving using of the various purification mechanisms took years before they were finally introduced in the market. Had there been no research activities, the world would have turned out to be a difficult place to live in. And it is no exaggeration if it is said that the introduction of water purifiers is one of the most significant effects of research!

Amid the purification processes, one mechanism widely used across the world is reverse osmosis filtration. It was in the year 1748 that Jean Antoine Nollet, a French clergyman and physicist, first observed the process of osmosis through semipermeable membranes. Nollet was the first professor of experimental physics at the University of Paris. His experiment did not find commercial or home usage except being observed in the laboratory for the next 200 years. A home water purifier during those times was a typical conventional type until the first investigation of desalination of seawater using semipermeable membranes was done in the year 1949 by the University of California at Los Angeles (UCLA). Along with efforts of researchers from the University of Florida fresh water was produced from sea water involving the use of reverse osmosis filtration. The process was gradually adopted worldwide though it still took few more years for people to know and accept use of water purifiers with reverse osmosis filtration mechanism.

Use of the RO home water purifier is a popular trend in almost all countries across the world. Its use is recommended in areas where total dissolved solids in water are high. The reverse osmosis filtration process involves application of pressure to the solution when it is on one side of a selective membrane. Pure solvent, i.e. water molecules, passes to the other side while the solute is retained on the pressurized side. An RO home water purifier should come with multiple filters so that life of the membrane is enhanced and only 100% pure and safe water flows from the faucet. These filters, usually optional, may include sediment filter, activated carbon pre-filter, RO membrane, mineral preserver, post taste enhancer, etc.

You will come across numerous water purifiers of reverse osmosis filtration mechanism in the market. Not all purifiers guarantee purification effectiveness. Conduct research online, read reviews and users’ comments; it is then only that you can get the best RO home water purifier.
