Do you occasionally see particles or sediments in your cup when you fetch water from the kitchen tap? Or do you ever fear that those irritating green plants have contaminated your plumbing? Perhaps you just want to ensure a 100 percent clean water, free of toxic chemicals, germs, and solid contaminants? Well, a reverse osmosis system is what you have been looking for.
A reverse osmosis system forces water molecules through ultra-small holes that usually make up the filtration membrane, and often there are several layers of these filters, each catering to trapping different forms and types of contaminants, to deliver to you pure and ultra-clean water.
And in this article, we are going to highlight our top picks for the best reverse osmosis systems as well as share our buying guide which we used to select the very best of these products from the myriads available in the market.

Things to Consider When Shopping for the Best Reverse Osmosis System
Before heading on into our specially selected reviews, a buying guide is essential to help you know what exactly to look for in a Reverse Osmosis system. As these systems are usually a bit costly, it is vital to pick one with the most value while being considerate of its price. The essential factors will be discussed below but know that there is more to choosing an RO system, and these other factors will be better highlighted in the review that follows.
Efficiency & Water Wastage
Many, if not most Reverse Osmosis (RO) Systems are water waters. Usually, about 80 percent of the total water intake of these systems doesn’t get through the filtration process.
Hence, you have water you know for sure is contaminated, but that cannot be ingested. Thus, efficiency in regards to RO systems refers to the percentage of clean and useful water that comes out of the faucet compared to that your pipes supply it.
Excessive water wastage leads to an increase in your utility bill for the water you did not even use. To avoid this, you want a highly efficient RO system.
When your reverse osmosis system starts letting leaky water into your tap, then the point of the process is defeated. Different RO system manufacturers go about solving this issue in a lot of different ways, including leak detection notifications using LED lights, automatically shutting off the water supply to your faucet, etc.
However, you should ensure to only purchase one that you can be sure won’t betray your trust by serving you contaminated water when you think it has been purified just because of a leak.
Filtration and Purification
Different filtration stages are present in RO systems. The general ones include the sediment stage for solid contaminants, carbon stage to combat chlorine and other toxic chemicals, and the reverse osmosis stage where the primary purification occurs at a molecular level.
A number of different filtration stages are available as well for various purposes, but these usually drive up the price of the RO system. So you should pay attention to this in order to choose a product that suits your specific needs.
The one filtration stage you, however, should look out for the most is the alkaline remineralization stage that functions to re-introduce useful minerals into the already filtered water.
The thing is that pure water is slightly acidic. And other than the health risk acidic water poses, it just doesn’t taste as refreshing as water with natural minerals. So this stage of the purification process “remineralizes” the water, adding a bit of alkali to balance the acidity and ensure that your purified water tastes fresh and refreshing as well.
A price can never be placed on safety, especially an essential product as the water we take in, hence the need to invest in robust and dependable water reverse osmosis systems. We hope this article has been able to make your decision-making process easier.
