Reverse Osmosis: Why Is It a Great Choice?

After reading about Reverse Osmosis systems, the next step would be deciding to purchase one. But why is it the perfect choice for a water filtration system? Before we give you the advantages, give us the chance to explain what in the world Reverse Osmosis even means. Let’s start with the basics, shall we?

Reverse Osmosis (RO)

This is the process of demineralizing or deionizing water by pushing the water under pressure through a semipermeable RO Membrane.


To comprehend Reverse Osmosis, one must first understand the process of Osmosis. I mean, I guess that’s given.

Osmosis is a process wherein molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one. In other words, it’s where a weaker saline solution “migrates” to a high saline solution, just as plant roots suck up water from the soil and human kidneys get water from the blood.


In case you were wondering, a less concentrated solution will really have a natural tendency to move to a highly concentrated one. Just imagine having a can full of water with low salt concentration and then having another can full of water with higher salt concentration. Now imagine that they’re separated by a semipermeable membrane (I know it’s a bit difficult to imagine but just bear with me). Because the membrane allows some of the substances to pass through, the water with low salt concentration would then start to transfer to the can of water with high salt concentration.

Semipermeable membrane

Still confused? Let me define what this membrane thingy is. A semipermeable membrane allows some molecules or atoms to pass through it by diffusion. Take for example a screen door. It permits air molecules to pass through it, but insects or anything bigger than the holes can’t pass through. Let’s have another example—the Goretex synthetic fabric which contains super fine plastic film into which millions, even billions of tiny pores have been cut. These pores are sufficiently large to allow water vapor through, but it’s small enough to block liquid water.

Reverse Osmosis…again

Now, do you have any idea what reverse osmosis is? That’s right! It’s the osmosis process in reverse! Quite obvious, isn’t?

However, reversing the naturally occurring phenomenon of osmosis requires energy and the application of that energy to the more concentrated solution. You’re probably aware of the components of an RO system already, and you might have come across its RO membrane. Though this membrane permits water molecules to pass through, it rejects the majority of dissolved bacteria, salts, organics, and pyrogens. To do this, enough pressure should be used to push the water through the RO membrane. Pushing the water allows it to get desalinated (demineralized or deionized) in the process, enabling pure water to go through while blocking most of the contaminants.

Now that you understand osmosis and reverse osmosis, you’ll appreciate the following advantages even more!

Perks of Having an RO System

RO systems improves the taste of water

Thanks to the powers of Reverse Osmosis, contaminants such as salt, particles, colloids, and others are removed! Now, you can enjoy drinking water that doesn’t only smell great, but tastes good too!

RO systems remove contaminants

contaminantsRO systems can also remove pollutants like pesticides, nitrates, fluoride, bacteria, sulfates, arsenic, pharmaceuticals, and more. If your RO system uses a carbon filter, it can also remove chloramines and chlorine. There’s no better way of cleaning water than with an RO system!

RO systems are easy to maintain

Yup, you’ve read that one right! These water filtration systems have few moving and replaceable parts, making cleaning and servicing hassle-free. Plus, if you take care of your RO system the right way such as following the annual cleaning process and changing out the filters, it can stand the test of time. RO systems that have been properly-maintained can even last up to 15 years!

RO systems can save money

Sayonara, water delivery services! Owning an RO system will also save up your money by providing all the safe, clean water you’ll ever need. You don’t have to buy cases of bottled water too because RO filtration provides safe-to-drink water.
