Reverse Osmosis Water Purifier – Factors to Consider Before You Buy One

By | March 14, 2017

Drinking safe, pure water is such an underrated necessity in life that it is a shock how many people invest in their daily luxuries than ensuring their families that they will not get sick by drinking water. But one reason behind is it that these necessities do not get advertised with the same flair that SUVs and designer brand bags do.
Here are the things to consider when buying yourself a reverse osmosis water purifier:


This should never be a problem when it comes to this, but ironically, many would far rather get a modest water purifier instead than resort to ridding themselves from an excessively luxurious lifestyle. That’s on them. We believe you’re different; you wouldn’t be reading this article if you didn’t care much about your health as well as the wellbeing of your family.

For a GBP 150, you can already get a fully-functioning unit. However, you cannot expect quality and longevity, in comparison to their more expensive contemporaries. Middle-ranged RO systems fall somewhere between GBP 200 to GBP 450, and these can already do the job efficiently. However, if you want to take it one notch higher, you can perhaps consider investing in a GBP 1000 RO unit.


This is usually directly proportional to the amount of the system you desire to purchase. Just remember: the more stages the system has, the more effective its filtration is. That seems pretty basic enough.

For example, a four-stage RO unit probably has a sediment filter for sand, pebbles and other earthly materials. Another would be a carbon filter, which will not permit other chemicals from passing through. Of course, there’s the semi-permeable reverse osmosis membrane which will safeguard the unaccompanied passage of water alone, while others that have a bigger molecular weight. After that, is a post-carbon filter, to take care of other contaminants that might have escaped from the three previous filters. In the UK, you won’t usually need to have more than this. But for those places that do not have as much privilege when it comes to this, producing clean, pure water to drink might require more than four filters.

Size and Amount of Water

This is also another factor that needs to be considered, as not all RO systems produce the same output, and exert the same reverse-osmotic pressure to counter the naturally-occurring osmosis. The product specifications will tell you how much water a particular system can      handle in a day. The most common sizes are usually capable of 50-100 gallons.

Amount of Waste Produced

So what happens to the water that did not successfully pass through the filters? They become wastes, as it is necessary for the system to retain some water for it to be able to remove the contaminants from the system.

There are some RO systems that allow for you to use the waste water, however. Some don’t mind using it to wash the dishes, clean the house, or water the plants. If you want to have safe water for drinking and cooking purposes, and minimize waste, you can try out zero-waste systems.


Installing an RO unit can cause you some trouble. If you’re just going to have to go through it, why not install something that can last long? Do not entrust everything to customer reviews, although they can already do the legwork for you. Check it out for yourself, and compare the available units in your area. Buy the ones with warranty, and you can never go wrong.
