How do Reverse Osmosis Water Filters Work?

Before you can understand how reverse osmosis water filters work, you need to understand the principles of osmosis. While this term is probably familiar to you, most of us don’t quite remember those lectures from our high school science classes. In order to have osmosis, you need to have at least two chambers which are separated by a semi-permeable membrane. This is any substance that allows certain particles through but not others. The walls of our intestines are a great example of a semi-permeable material.

If you have two fluids on each side of the membrane, the fluid which has a lower concentration of impurities will go to the other side so the concentration is equalized. As a result, you are left with less “clean” fluid and a “less dirty” fluid on the other side. Obviously, this does not help us when it comes to cleaning our drinking water. Reverse osmosis changes the process of osmosis by adding pressure to the side with a higher concentration. The fluid passes through the membrane and we are left with more clean fluid.

Reverse osmosis water filters are effective ways to remove bacteria, pathogens and minerals. However, many chemicals are smaller than water so they also may pass through the membrane. That is why good reverse osmosis water filters often work on several different levels with different filter and purifications systems included. These systems are often divided into many different steps and almost always include an additional carbon filter to remove chemicals and chlorine. That is why reverse osmosis water filters usually are several smaller chambers rather than just two. While they may not be the cheapest home water treatment systems, reverse osmosis filters are one of the most effective.
