Key Factors to consider before buying a Reverse Osmosis System


The importance of safe and clean drinking water is a matter that cannot be debated or understated. As time has continued to elapse with every generation, the quality and quantity of drinking water has continued to reduce even as the number of users is swelling due to the surging increase in human population. This increase has led to the invention of all sort of technological interventions to try and sort these water issues so that we don’t just have the right quantity of water available to people, but also the right quality. Reverse osmosis system is one of the most effective water technologies that help in the production of safe and clean drinking water.

But one thing that is common about all these systems is that they come at a cost and this means that the potential buyer needs to make other considerations in order to get real value for their money. That is why all reverse osmosis system reviews contain both monetary and non monetary factors to consider before you buy an RO system. This article therefore seeks to explore some of the most important factors that you will need to consider outside the cost bracket so that you can get something that will serve you better and for longer with considerable ease. Stay with this article till the last period in order to discover more.

Establish what you want to remove from your water


The first factor you need to consider is the kind of contaminations that you would like to remove from the water you use in your home. In addition, you need to establish the degree of contamination in the water before moving forward and getting an RO system. This is very important because RO systems are meant to purify water from contaminations and it is necessary to establish what these contaminations are first or else the decision to buy the system will be void. To get over this stage, you need to take samples of the water you are using for water analysis by qualified water bodies near you. Some of the places you can take the samples for analysis are municipal water departments and certified laboratories.

The quantity of water that you need to purify

Another important factor to consider is the quantity of water that the system is intended to purify. This output level is usually tested and determined on a daily basis and the potential buyer needs to be clear about it beforehand. The reason behind this is that the daily output of the system will directly affect and determine other important features and factors about the RO system that you will buy. For example, this variable will determine the size of the system that you will buy; this is not to mention that it will also determine the size and type of membrane that the system will have. In addition, the daily output of the system will also determine the size of the holding tank.

The types of membrane in the system

Another factor that you need to consider before you settle for a particular RO system is the type of membrane that it is fitted with. This is because different RO systems have different types of membranes. The decision to settle for a particular type of membrane will be inspired by other factors such as the presence of chlorine in the water. Some of the types of RO membrane are listed below as follows:

  • TFC or thin film composite membranes are made from synthetic material and they remove between 94 and 98% of water contaminants. These types of system usually have carbon pre-filters that safeguard the membrane from chlorine-related damage. These types of membranes are ideal for water that contains chlorine and water that is free from chlorine.
  • Another type of membrane is the CTA or tri-acetate membrane. This kind of membrane is made from organic material and it is able to remove between 88 and 94% of contaminants and it is the lowest removal rate compared to the other types of membranes. These membranes are suitable for chlorinated water.
  • The third type of membranes is the high removal membranes. They are synthetic in nature and have the highest rate of removal standing at 97.5-99% .They are very suitable for removing silicates and they also contain carbon pre-filters that ensure that the membranes are not damaged by chlorine. In addition, they are ideal for purifying both chlorinated and non chlorinated water.


The process of selecting a suitable RO system is attached to a number of factors that determine its overall performance in your life. You need to look for other vital factors that go beyond just how much or how less the RO system will cost you. These non monetary factors will help you to strike a balance that will enable you land a reverse osmosis system that is going to ensure that you enjoy it in all aspects, and not just affordability. Make sure that you prioritize factors such as the quantity of output, the removal rate, and the overall safety of the water. All these factors combined will ensure that you have a better user experience and definitely get the long-term value for money that you are looking for.
