RO-system – Buying Guide

Buying the best product is only a game of understanding your needs and requirements along with adequate knowledge of what you are going to purchase.

Look into some of the important factors that must not be overlooked while looking for various products that are available in the market. 

Water Source 


Talking about the basics, it is important to understand the type of your water source; city water or well water. 

Well-water contains a higher amount of contaminants than city water as it is treated in the plants, which determines the type of filter you need. Well-water needs a good reverse osmosis system with a UV light sterilizer to get 100% cleaning. 

Stage requirement of filtration 

Reverse osmosis filters come in variable stages of filtration as per the level of contamination in the water. For most people as standard 4-stages water reverse osmosis system is good to go. 

Whereas, sub0urban areas with well as a main source of water need to have a 5-stage reverse osmosis system that offers additional filtration for sediment removal. 

The pressure of the water 


This is another important yet overlooked factor that highly determines the performance of the filtrations system and that is water pressure. These filters require a specific amount of pressure to work properly. It is ideal to have at least 40 PSI of pressure to let it pass through the membranes for filtration. 

If the pressure of the source water is less than 40 PSI, you need to have a booster pump to increase the flow. 

Filtration quality 

Reverse osmosis systems vary depending on the technology that is being used in them. There are pre-filters and post-filters that determine the effectiveness of the whole system. Where some companies claim to give 99% cleaning of all the contaminants, but it is important to have a TDS meter to gauge the effectiveness of the filtration system. 

Go for WQA and NFS tested water filtration systems to have the best result. 

Water requirement


Different systems offer different water output as per their capacity and water intake. A regular production rate, GPD (gallon per day), is 600% to 80% approximately, which is ideal for optimal conditions that are hard to meet. For standard households a 50% GPD rated systems are adequate. 

There is no need to go for a larger system if not required. 


When it comes to water filtration systems, we do not only talk about the initial investment but there is maintenance cost that counts as well. Different systems come with different levels of maintenance, depending on their manufacturing, design, and components that are included in the system. 

Maintenance counts for changing of filters and replacement of faulty parts. To save yourself some bucks, go for the system with affordable and easily available filters and spare parts. 

No matter how many types of filtration systems are available in the market, reverse osmosis systems are the most effective than any other option that is available in the market. The basic components that need proper consideration are sediment and carbon filters, holding tank, and RO membrane that creates the whole difference among the products when it comes to quality and performance. 

The right choice can save you from a lot of trouble in the future. To make it easier for you we have gathered the best products that are available in the market.
