Advantages & Disadvantages of a Reverse Osmosis System- All you need to know

What is a Reverse Osmosis

Reverse osmosis (RO) is a water purification process that uses a partially permeable membrane to separate ions, unwanted molecules and larger particles from drinking water.

They can remove many types of dissolved and suspended chemical species as well as biological ones (principally bacteria) from water, and is used in both industrial processes and the production of potable water. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side.

Requires a lot of water and energy to undertake the process which is quite unfortunate. However it raises the pH to around 7/8 making it 97% pure drinking water. Every 4 Litres, it wastes 1.5L of water.

How does a Reverse Osmosis Work

Water is accessed via a separate faucet on top of the bench sink or by a 3 way mixer and comes complete with a stainless steel storage tank. .

By storing the pure water ready for use., they quietly and automatically produce pure water and shuts off when the tank is full.

When required, pure water is drawn from the storage tank. And then receives a final polish from the chemical reduction cartridge, just prior to drinking. It produces only the best tasting, pure drinking water for your good health.

Removing ions, unwanted molecules and larger particles from drinking water making it 97% pure by raising the pH. Also filters bacteria, parasites and repels heavy metals plus removes fluoride and hydrocarbons

Pros of a Reverse Osmosis

Exceptional Water QualityHealthier Drinking Water For You And Your Family
Chlorine and Fluoride RemovalRemoves Chlorine And Fluoride From Your Water
Better Tasting WaterBetter Tasting Water Means Your Family Will Drink More Water
Minimal MaintenanceYou Only Need To Change Filters Every 6 To 12 Months On Average
Saves You MoneySaves You Money From Buying Bottled Water
Convenience97% Pure Water On Demand
Odor-Free WaterNo More Odd Smelling Water
No Water Jugs To ChangeLess To Store And Lift Heavy Water Jugs

Removes Many Contaminants:

Nitrates and Nitrites (hexavalent & trivalent)
Cysts (Cryptosporidium)
Total Dissolved Solids (TDS)

In addition if don’t like the smell and taste of chlorine in your water, and you don’t want added fluoride in your drinking water, a reverse osmosis drinking water system with an activated carbon filter is perfect for you.

An activated carbon filter is different than a reverse osmosis membrane as it can remove particles that are much smaller than the reverse osmosis membrane can catch.

As a result, having a reverse osmosis drinking water system that has an activated carbon filter along with a reverse osmosis membrane will provide you and your family with quality water. Without the unwanted salt and chemicals that can be found in many water supplies.

Cons of a Reverse Osmosis

Initial InvestmentSmall Investment With Big Future Savings
Slow Water ProductionFills A Storage Tank Slowly
Removes Beneficial Minerals Reduces Some Beneficial Minerals That Are Also In Many Foods
Wastes Alot Of WaterFrom Every 4 Litres, it wastes 1.5L of water
RO Water Is Too PureIf Your Water Is Very Pure Already, You Probably Don’t Need Reverse Osmosis

To clarify you will need to the put the waste water either down the sink or into a storage container as grey water so you can water your plants or use it on the lawn. Not to be consumed! Anything over a 5stage or more is an overkill and waste of money.

Meanwhile it does waste a lot of water and not to mention works pretty slow. On the average, to produce 4.5L of clean and filtered water reverse osmosis wastes about two to three gallons of water. Also, it takes roughly an hour to fill with clean water.

Generally, you should be changing your reverse osmosis filters once per year. Considering the small expense of the filters, it is worth it. The reverse osmosis membrane should be changed every 4 years.


Most importantly you will notice when it is time to change your filters as the flow rate with drop, the taste will be totally different or you might smell an odour.

Additionally you can get spare parts for all systems including faucets, connectors, housing O-rings. Spanners. Pressure limiting valves and much more here

The Advantages & disadvantages Reverse Osmosis is a vary of many things. Literally comes down to how much you want to spend, how many filters, how dirty your water is. We do have another option that don’t waste water but won’t get your water totally pure by having a fluoride filter in a twin system
