Reverse osmosis is a filtration method that removes harmful compounds found in water to make it potable. It uses pressure and a semi permeable membrane to purify water of impurities and foreign contaminants.
The RO filter has become very popular since its introduction to the market because more and more people are becoming aware of its benefits.
Though R.O. shower filter systems may be unnecessary in most cases, having a good supply of reverse osmosis drinking water would be healthy for pretty much anyone.
