Reverse Osmosis Water Benefits [The Good & The Bad]

This is a brief list of reverse osmosis water benefits and the benefits of using a reverse osmosis water filtration system.

Choose the questions that you want to see the answers.

Let’s start with the RO water.

What is reverse osmosis water?

Reverse osmosis water is purified water that has undergone filtration through a reverse osmosis system to remove impurities, contaminants and other substances like minerals. The water is completely clean and it’s ideal for drinking.

A reverse osmosis system provides a simple and effective solution for purifying your water and making it safe and clean both for consumption and other uses.

Below are several distinct benefits of the water that come with using an RO system.

The Good

Reverse osmosis water benefits

Eliminates Sodium

The first huge benefit of using an RO system is that it gets rid of virtually all the sodium in your water. This is a great benefit because sodium is known to cause high blood pressure, kidney disease as well as liver problems especially when consumed at high levels.

Many water softeners can’t achieve this since they are only capable of removing hard water minerals such as iron.

Removes Lead and Other Contaminants

Lead is another very common contaminant found in water.

Like sodium, it has extremely detrimental health effects when consumed at high levels. It can increase high blood pressure, cause kidney issues, nerve damage and has even been linked to infertility.

It can also cause serious developmental problems in infants or even cause anemia in children.

Reverse osmosis systems effectively remove all traces of lead from the water making it safe for consumption.  

Apart from lead and sodium. RO rids your water of many other particles, chemicals, and contaminants that can adversely affect your health, this includes cryptosporidium parasites, iron, manganese, arsenic, bacteria, and viruses.

Better Tasting Water

Water from the tap often contains chemicals such as chlorine and fluoride which have been intentionally added to it. Together with other contaminants and impurities, these substances end up influencing water’s natural taste making it unpleasant.

By removing all these additives, chemicals and particulate matter, RO filters not only enhance the quality of your drinking water but can also drastically improve the taste and odor.

It produces water that’s pure, fresh and tastes much better than regular tap water.

No Operating Costs

Most reverse osmosis systems (except the ones with a booster pump) solely rely on natural flow and water pressure to filter out contaminants hence add nothing to your electric bill. Therefore, for those that want to utilize as little energy as possible to purifier their tap water, an RO system can be of great benefit. 

Saves space

Reverse osmosis systems are often compact and much smaller in size compared to other typical home water filtration systems. They occupy very little space, about the size of a small traveling suitcase. 

They can fit right under a kitchen sink or even in tiny corners.

Moreover, you can personalize some RO units to fit your home, so if your house falls on the small side, then a RO system can certainly be very convenient.

Easy to Maintain

Maintaining and taking care of a reverse osmosis system is a breeze for the most part as the system is fully automated.

It usually requires maintenance every 6 months or so, and typically the only you will need to do once installed is changing out the filters to keep the system running at its peak capabilities.

You can either do it on your own or hire a professional water contractor or plumber to do the job. The rest of the unit runs automatically, without any assistance while the semipermeable membranes can go for up to 3 years before requiring replacement.

Money Saver

Finally, another best benefit of using a reverse osmosis system is that it can save you a lot of money especially if you frequently purchase bottled water for drinking purposes.

Even many bottled water manufacturers utilize an RO system to produce pure water.

Therefore, by having your own RO system, you can generate bottled-quality water at the comfort of your home whenever you want for no additional cost whatsoever.

You can even buy reusable water bottles, fill them with your RO filtered water and take it with you to the office or any other place saving you the cost of having to purchase bottled water.

The Bad

Although reverse osmosis systems offer substantial benefits, they do have some downsides too that are considering when purchasing a unit.

They include:

Removal of Essential Minerals

One of the major drawbacks of a reverse osmosis system is that due to its excellent filtration system, it also ends up getting rid of healthy minerals like iron, calcium, and magnesium which are naturally found in water.

These minerals are essential to the body as they aid in overall muscle and heart health and without them in the RO water can lead to mineral deficiency in the body. However, using a re-mineralization filter alongside your RO system can help replace these beneficial minerals.


The small pore of a reverse osmosis membrane can become clogged especially when the filter replacement does not meet the system guidelines or the maintenance schedule is not followed.

Ensuring that you invest in an RO system that has a sediment or carbon pre-filter and doing routine maintenance can help reduce the chances of clogging.  

Slow Process

While reverse osmosis provides high-quality water, it’s a relatively slow process compared to other water filtration methods.

This is mainly due to the fact that the system relies on water pressure. Therefore, if you need a large amount of water within a short time, then you will have to be a little patient and allow the system to refill the RO storage tank.

May not Kill all Bacteria

There’s a high chance that a fraction of microorganisms and bacteria can pass through the RO membrane. It’s quite rare for this to happen but using a complete RO system with additional stage containing UV light filtration can help prevent the probability of microbiological contamination.

The uses of a reverse osmosis system

Reverse osmosis system use is growing rapidly but it finds frequent use in the following areas:

Filtering Drinking Water at Home

Many households around the world use reverse osmosis systems alongside water softeners to purify and soften water entering the house for drinking, cooking and other purposes.

Production of Bottled Water

Reverse osmosis systems are used in bottled water factories in the production of bottled water.

Water is passed through an RO water processor where pollutants and microorganisms are removed.

Food and Beverage Industry

Reverse osmosis system is extensively used in food and beverage processing plants as a more economical method for concentrating food liquids like fruit juices.

It’s also widely used in the dairy industry purposely for the production of whey protein powders.


The pharmaceutical drugs industry requires highly-purified water that is free of bacteria, dissolved solids and other contaminants for production purposes. Therefore, many companies utilize RO systems with UV sterilizers to treat and disinfect the feed water in order to produce the high-purity water needed for production processes.


Freshwater aquarists also use reverse osmosis systems for filtering tap water that enters their aquariums to remove excess chlorine and other contaminants which can lead to excessive or unwanted algae growth.

Boiler Feed-Water Treatment

 In industry, reverse osmosis systems are extensively used to remove minerals and impurities from boiler feed water as they can cause corrosion or leave deposits inside or outside boiler tubes resulting in reduced efficiency and poor steam production.


Reverse Osmosis is no doubt one of the most effective and efficient water filtration systems on the market. As you can see, the system offers many benefits despite having some disadvantages.

The good thing is that all the disadvantages of a reverse osmosis system are relatively mild compared to other water purification methods.

They can easily be corrected by incorporating other filters or purchasing a complete RO system that features extra filtration process like re-mineralization filter and UV light filter.

Therefore, if you are looking for the best way to purify the tap water in your home, then you should consider getting an RO system.


What is the pH level of reverse osmosis water

The pH level of water produced by a reverse osmosis system ranges from 5.00 to 6.00. The reason for this is that the system removes most of the buffering alkalinity. However, the acidity in RO water tends to be very weak which makes it not much of concern. Plus a re-mineralization filter can help improve the pH to a neutral point which ideally 7.00.

Is reverse osmosis water safe to drink?

Yes, it is. Reverse osmosis water (RO water) is safe to drink as the RO system removes up to 98% of lead and contaminants from water and frees people from many diseases such as high blood pressure, nerve damage and low fertility.

Is reverse osmosis water distilled?

No, it isn’t. RO water is the result of the reverse osmosis process that uses an external pressure (water pressure) to force the water to overcome the osmosis flow through the RO membrane while the distilled water is water that has been boiled into vapor and condensed back into liquid in a separate container.

Is reverse osmosis the same as distilled water?

No, they are different. For example, a water distiller does not remove chlorine and other chemicals completely from water while an RO system does.

Is reverse osmosis water safe for neti pots

In theory, the answer is Yes as the RO water is clean enough, but if you choose to make your own saltwater for neti pots, distilled or sterilized water is recommended, so you better follow the instruction.

Is RO water acidic?

Yes, it is. The pH level in RO water often drops below 7.0 ranging from 5.0 to 6.0 and it is considered acidic.

Is RO water bad for you?

No, it isn’t. Even RO water is acidic and lacks some minerals that good for your health, the RO water is not bad for you as you can have the minerals from your food and the pH level of RO water is about 5-6 is still higher than the pH level in your stomach which is about 2.
