Which Water Filter Removes the Most Contaminants?

Reverse osmosis, or RO, is considered the most economical method to remove 90% to 99% of all impurities from the water. The structure of the membrane in an RO purifier is much smaller than UF or other membranes. It can reject practically all kinds of particles, bacteria, and organics. Many leading water plants are using reverse osmosis technology. Naturally, osmosis happens when the solution of two different concentrations is divided by a semipermeable membrane. Osmotic pressure drives the water through the RO membrane, where the water dilutes a more concentrated solution ending in a more balanced result.
