The reverse osmosis system was originally developed for industrial use in printing and photo processing but because of the need for clean water, systems have been adapted for domestic use. Finding the right reverse osmosis filter system for cleaner water at home is important if you understand that there are more than 2000 toxic chemicals in our drinking water.

Reverse osmosis is a process that makes use of high pressure to force unpurified water through a semi-permeable membrane so that toxic chemicals are removed from the water. The only problem with this system of ‘cleaning’ water is that while toxins are removed, almost all other minerals (even trace minerals) are often also purged from the water, leaving water without any nutritional content.

It is important to understand that the concentration of toxins, water pressure and quality of membrane used to design a filtration system. There are generally two types of membranes used in reverse osmosis – the cellulose triacetate (CTA) membrane and the FTC membrane – each with their own functions. While CTA membranes are organic and more cost effective, they tend to attract bacteria growth and sometimes may generate a smaller volume of water with a lower quality.
