Inverse osmosis

Glass of water

You have probably heard of reverse osmosis, since many people from all over the world decide to install a unit in their home.

The main reasons to do so is because they are concerned about the quality of their tap water or simply wanting to improve its taste.

What is it?

It is one of the most complete and effective water filtration methods. It's about a chemical treatment used to purify tap water. The result is a better taste and healthier type of water for drinking and cooking for people with certain diseases.


Simply put, reverse osmosis devices filter water through special membranes. Using a certain pressure, they leave out practically everything that accompanies tap water: external pollutants, solid substances, large molecules and minerals.

The purified part is ready to drink, while the other part is diverted as wastewater. That is, it is discarded. This means that reverse osmosis consumes large amounts of water.



The reverse osmosis filtration system can remove lead. Too much lead in the body can lead to high blood pressure, infertility, and other health problems. That's it beneficial for people with certain health problems, such as people with a very weak immune system or who need to eat a low sodium diet.

It is also worth noting that reverse osmosis water does not contain Cryptosporidium. Once ingested, this parasite from contaminated water causes fever and diarrhea. It is especially dangerous for children, who can lead to dehydration and malnutrition.

Reverse osmosis makes tap water taste better and contributes to reducing the use of plastics. As an alternative to bottled water, it can also save money. However, it depends on the price of the appliance, the spare parts and the revisions.

How to have a home reverse osmosis system

Home reverse osmosis systems are often installed in the kitchen, specifically under the sink. Thus, the most important step prior to installation is check if there is enough space for one of these computers in that part of the kitchen.

Once you have made sure that you have a place to put it, you must decide on the make and model. Today's market offers numerous options to suit all budgets. Prices range from 100 to several thousand euros depending on the technology and materials with which it is manufactured. However, to that we must add the price of the installation, the revisions, the annual spare parts and the possible breakdowns.



There are mixed opinions about whether it is healthier than tap water when it comes to healthy people. Some say that it is healthier, while others find it neither better nor worse than normal tap water. Among its detractors, there are also those who come to consider it dangerous because this system changes the parameters of the water.

Also, reverse osmosis units are accused of wasting too much water. And the truth is that pulls a lot more than it produces. Many people dismiss it because of it.

In addition, these units need maintenance. Otherwise, pollutants accumulate in the filter and can cause a deterioration in the quality of the water, which is just the opposite of what is sought when opting for a water filtration system for the home. And that, of course, entails an annual expenditure of money.

Taking into account both its pros and cons, as well as the particularities of each home, It is up to each one to decide whether to opt for the installation of a reverse osmosis system Or conversely, continue to use tap or bottled water, or a combination of both.
