How To Choose A Reverse Osmosis System

In choosing an outstanding water filter, experts are of the opinion that Reverse Osmosis System is the best. Reverse Osmosis System (ROS) as a water purification technique employs a semipermeable channel to sieve small particles, bacteria, and some pathogens from drinking water. While removing contamination’s through filter, Reverse Osmosis System also neutralizes the taste and odor of water, making it a much-demanded requirement during water filtration processes.

As reliable as this system, choosing a trustworthy Reverse Osmosis System may be somewhat hard especially if you are buying for the first time. The market has too much reverse Osmosis System in stock, getting a standard one may not be easy.

To tackle the problem of not knowing the right Reverse Osmosis System to choose, we have prepared a detailed market guide to getting the best of the bests. 

The Capacity Of The Filter

The capacity of a Reverse Osmosis system is important especially if it is intended to be used for industrial purpose. A small filter may not serve a large volume of water to those who need it, instead a big ROS is needed.

In case you have a limited space in your home or industry, a big Reverse Osmosis system may not be advisable for the kind of setting; else, you will have to send it back to the seller. To be free from this problem, it is necessary to measure the available space, and purchase the system that fits into this space. 


You need to consider the cost of RO-System you are buying. A costly Reverse Osmosis System may not be your demand at a time. The market is saturated with too much costly RO-System due to different output and capacity. However, these products come with different prices.

The cost of an industrial RO-System may be hugely higher than the ones designed for homes because they generate hundreds of liters of clean and refined water.

While choosing RO-System, you must take note of the maintenance cost that may be involved, using possible repair expenses for a year to determine this is good. A product without available spare is not advisable since the cost of maintenance may be high, and the hardships that would be taken to repair it might be unbearable. Some RO-System do not have repairer in some environments, while some have but their spares are expensive to buy or scarce. 


For most product, the present market is filled with varieties of manufacturer and different quality. Surely, the quality level, on most occasion is directly proportional to the live span of the product, durability and functionality. The quality of a product is dependent of the materials used in making it.

Depending on what you want to use your RO-System for, the quality is an important factor one should consider when choosing a RO-System. Since quality is likely to have effect on the functionality of a product, and you need a filter to dispense out drinking water, you should select a RO-System that will give out a standard pure water. When getting a RO-System, you also should select a type that will be durable, long lasting and does not break down often. You also need to select one that has a warrant attached to it. 

Number Of Stages In The RO-System

The number of stages found in the filter varies from one to another, and it has effect on the quality of water dispensed out of, it stability, and how prone it is to problems. Comparing a 5 stage system to a 3 or 4 stage system, the result you will get from a 5 stage system will surely be better than that of a 4-stage or 3-stage system. A 5-stage filter is less prone to problem, more stable, gives better water quality, and the filter is not replaced frequently. With the 5 stages, you’ll save more money and get a better quality. Confidently, I will advise you to get a 5 stage RO-System over a 3 or 4 stage RO-System.

Arrangement Of Filter

This is an important characteristics of a Reverse Osmosis System you should take cognizance of. Understanding the benefit of the filter arrangement in a RO-System will enhance your choosing ability.

Usually, before the reverse osmosis membrane, you will have 3 filter that comprises of a sediment filter and two carbon blocks. Firstly, having this three is important, the composition and arrangement in the right manner is also very important because the quality (purity) of the water is dependent on these factors. Some RO-System is equipped with two-sediment filter and a carbon block because a sediment filter is cheaper than a carbon block, but this will never give you a good quality RO-System. Also, a good quality RO-System is made of 2 carbon filters placed before the RO membrane (stages 2 & 3) so that the carbon filter will protect the membrane from the damage of chlorine. exposure

Type Of Carbon Filter

You also need to consider the type of carbon filter in a RO-System before selecting one. The best carbon filter is a block carbon type because it prevents the membrane from chlorine effect and don’t leak out carbon powder that can block the system. This is unlike the granular activated carbon filter and the small in-line filter.

Water Contamination Level

Choosing a Reverse Osmosis System, the contamination level of the water needs to be evaluated, as it will help you determine the number of filter you actually need. Basically, a much more contaminated water require more number of filters and vice-a-vice. You can test the level of purity with the aid of some home test kits sold in the market and you will have a perfect idea on the number of filter the RO-System you will get should contain.

To conclude, it is quite important to safeguard what you take into your body system especially water, therefore, you need one of the devices that can give you the best quality of water. Reading this article, you have been informed about the criteria you should take cognizance of when selecting a reverse osmosis system.thanks to team hellojuicer for helping us to make this guide
