How Reverse Osmosis Works Reverse osmosis is the same process used by many of the major bottled water suppliers. By purchasing a Whirlpool® Reverse Osmosis Filtration System, you can have the highest-quality water available from your own faucet for a fraction of the cost of bottled water. Just how does the reverse osmosis process work? During the process, water is forced through a semi-permeable membrane that traps contaminants. These contaminants are then flushed out of the system and down the drain, leaving your drinking water clean and fresh. The reverse osmosis filtering process reduces dozens of contaminants. Here is a short list of the most common contaminants.
