How To Use And Maintain RO Water Purifier

When we think about drinking clean and pure water, an RO Water Purifier system is the first thing that comes to mind.

Reverse Osmosis systems or RO systems are now very familiar and very commonly used home appliances without which it is difficult to drink water and even cook food.

If you are someone who has an RO system installed at home, then you must know not just about its working but also you have to be aware of its proper maintenance and cleaning process. 

Working Process Of RO Water Purifier 

Jean-Antoine Nollet, a French physicist first observed the reverse osmosis process in 1748. After a lot of research over the year, in 1977 Cape Coral in Florida was the first municipality in the US think to use the RO process.

RO purification systems use pressure to push water through a semi-permeable membrane, and also eliminates the contaminants from water.

The section of the purifier which is drinkable water contains smaller particles whereas the other section has large ions and molecules that have been eradicated from water.

Some of the common contaminants that make water polluted are arsenic, lead, and nitrates, which can be effectively removed by the Reverse Osmosis process.

Here we will discuss some maintaining tips for RO water purifier that will make your purifier more efficient and keep it in top condition.

Taste The Water Quality

Before purchasing a water purifier, it is highly recommended to get a water quality test in your area.

Proper analysis and research by an expert to determine the type of impurities that are present in water.

Check The Positioning Of The Purifier

Another essential factor that you need to consider where is setting the water purifier.

Depending on the type of kitchen area and surface that you have, you can choose between wall-mounted or under-the-counter water purifiers.

Traditional Indian kitchens are suitable for installing wall-mounted water purifiers. On the other hand, the counter water purifiers are suitable for modular kitchens which have less space.

The water purifier can also be placed in an area where there is a normal temperature. If the place where the water purifier is placed and installed has moisture, water may freeze during the winter season.

Install A Softener For Extra Efficient Functioning Of The RO System

You can wonder whether installing a softener is a good idea in combination with the RO system or not. Well, a softener and an RO system actually make a good combination as they both can result in good tasting and very clean water.

A softener is important for some cases, the presence of magnesium and calcium can make the water hard and difficult for the RO system to do its purification alone.

Maintain the Water Pressure

RO membranes are the most expensive part of this system. As a result, it is extremely important to avoid doing any harm that may damage the RO membrane.

An important factor that you need to keep in mind and check on is the water pressure. The RO membrane can be get damaged if the water pressure is too high.

Before installing a water purifier, you have to make sure that you check the inlet water pressure to avoid damaging the RO membrane.

Clean And Sanitize The Water Purifiers

An efficient way to enhance the life of the water purifier is to clean and sanitize it on a regular basis.

You have to get the RO water purifier thoroughly cleaned at least once a year with the help of a professional.

Additionally, if possible get the water purifier sanitized to ensure that there are no chances of spreading any infections.

Change The RO Filters

RO membranes can damage due to the heavy work that it does on a daily basis. As a result, it is necessary to replace the RO membranes at regular intervals or when the machine indicates to do the change.

Make sure that you replace it with a high-quality RO membrane as it will not damage easily and ensure that the water purifier functions smoothly.

There is also some internals that you have to change also in a regular basis. 


A pre-filter cartridge is used to separate silt, sand, and other components. It protects the RO membrane from any damage due to happen to these particles.

This cartridge has to be changed every 6-9 months in order to safeguard the membrane

Semipermeable RO Membrane:

Here the water is put under pressure and passed through this membrane in order to separate dissolved components like salts, minerals, etc. from water. In this way, only pure water flows through.

This membrane has to be cleaned every 3 to 4 months. This way the life of the membrane can be enhanced. Moreover, every 2-3 years, you have to change it without fail.


This is the last stage of water purification. It helps to reduce any taste and odor from water. It has to be changed every 6 to 9 months.

Polishing filter:

This is the last stage of our RO system. It is an activated carbon filter that makes sure crystal clear water and tastes good. A polishing filter must be changed every year.

Water Tank:

It has to be sanitized every year to get pure drinking water

Keep The Exteriors Of The RO System Clean

Besides the internal cleaning and maintenance, it is very important that you also keep the exteriors clean.

Make sure the outside machinery, as well as the tap attached to the machine, should be regularly wiped with either a dry or a wet cloth.

Frequently Asked Questions 

Why does the reverse osmosis system need maintenance?

To get optimum efficiency, routine maintenance should be performed on reverse osmosis systems. As a rule of thumb, RO systems come with three, four, or five-filter stages. This is important as chlorine can ruin the RO membrane. This carbon filter also should be replaced every 6-9 months.

How often do RO filters need to be changed?

For the pre-filter and carbon filters, you should aim to replace them about every six to nine months in order to protect the sensitive RO filter. The RO filter itself only has to be replaced every two to three years.

How do you make RO water taste better?

Reverse osmosis (RO) is so far the best way to enhance the taste of your drinking water. It reduces the amount of chlorine, total dissolved solids, and organic and inorganic substances present in the water which you get from your tap. Invest in a smart RO purifier that will give you high-quality water with a fresh taste

How long do RO filters last?

It is assumed that RO filters can last 2 years, and in some cases up to 5 years. It can generally be measured how you can maintain it and keep it clean.  

What is the average maintenance cost of an RO water purifier?

The average maintenance cost of the RO water purifier is approximately 1000-6000 rupees. It is quite costly.


So now that you get to know some easy ways and tips to maintain an RO system, you must make sure you keep that in mind and follow them so as to get the best usage out of your appliance.

Basically, by following these steps, you can make your system last for about 12-15 years. However, if you do not maintain it properly then the system might start working erratically and you have to either replace it or spend a lot of your hard-earned income on its repairing.
