What is a Reverse Osmosis System?

First of all, we should know what diffusion is. Molecules tend to move from a region of higher concentration to a region of lower concentration. This phenomenon is known as diffusion. Actually, Osmosis is a special type of diffusion in which molecules are water molecules, not other substances and the concentration gradient occurs across a semi-membrane which only allow water molecules to go through. Other ions or large molecules are not allowed to go through this membrane. Both diffusion and osmosis will be balanced until when equilibrium is reached. However, if sufficient pressure is applied to the concentrated side of the membrane, osmosis can be reversed. This means we can use this method to purify water. Sufficient pressure is applied to the water we need to filter and water molecules will go through the membrane while other icons or large molecules cannot go through it. And then we can get clean water.

A reverse osmosis system is a water treatment device basing on the basic principle of reverse osmosis. We can buy a household ro system to purify our tap water.

The following criteria can help you find the right one and we also use these criteria to evaluate these systems.


When you are looking for the best RO system, the overall performance is one of the most important things we should consider. The best models can remove a variety of contaminants, such as mercury, lead, asbestos, chlorine, bacteria and other dangerous chemicals. They also can remove the bad odor and taste from your water, providing you with an improved taste and odor.

Key Features

We also need to consider water temperature. A filter which can provide both hot and cold water will be better. In most cases, they only can provide cold water. Another thing you need to pay attention to is its operating pressure of the filter. The pressure must be suitable for your faucet, not too weak or too strong. Many of the best RO systems also come with an indicator which can remind you when you need to change and replace your filter. This design is very humanized, because we may forget to replace the current water and we may consume polluted water without any awareness, which is dangerous to our health.

Easy Installation

Try to find the filter which can be easily installed or you have to hire someone to install for you and cost your money. You can read some customer reviews to learn about the ease of installation. If it is difficult to set up, you have to hire one to change the filter when the current filter needs to be changed.


A high quality of a RO system is crucial, because you don’t want to fix or replace your system month after month. The best systems usually include warranties of 1 year or longer. Many exceptional models even provide satisfaction guarantees. You even can send it back if you have used for 30 or 90 days and don’t feel satisfied with the water results.
