When you think about the best reverse osmosis system, you think about water filters able to produce pure water with added minerals for better health and water taste. We have talked about water filters many times before, but today we will discuss each product as we included it into one of 3 main reverse osmosis systems categories: whole house water filters, under the sink water filters, and countertop/portable water filters. In other words, here are our best 8 reverse osmosis water filter reviews to help you make the best choice this year!

How Did We Choose Each of the Best Reverse Osmosis System for this List?

We focused our research with priority upon users’ needs:

  • Some need the best whole house water filters to meet all of their needs and homes. For this reason, you will find on this list an example or two of the best whole house reverse osmosis system money can buy in 2020.
  • Others enjoy more using under sink water filters for using cleaner, healthier tap water for cooking, washing, and drinking. These are the best reverse osmosis system choices if you don’t have enough space to install a more massive water filter and you need one only to purify your drinking water.
  • Many users prefer a portable/countertop water filtration system because they live dynamic and highly mobile lives. Just like faucet water filters and water filter pitchers, countertop water filters can come with you no matter where you go, so students and renters, we’re looking at you now!

In the search for the best products in each category, we asked for details from the manufacturers, browsed the forums and customers’ reviews, discussed with specialists in the field, and researched their environmental importance.

Before we start, you should know that most reverse osmosis systems on the market fall in the “under sink water filters.” However, we found some whole house RO systems and portable ones as well.

Best Reverse Osmosis System: Whole House Water Filters

For this category, we picked the four best reverse osmosis systems that meet the whole house water filtration criteria. You can pick the best whole house reverse osmosis system from this list in case you don’t want to go for one of the traditional whole house water filters we have talked about on a previous occasion.

In other words, they provide pure yet mineralized water for large homes and families, businesses, and even gardens. People prefer them when they register constant large water consumption daily or when they have to rely on well water, highly contaminated city water, and so on.

The APEC is impressive in its design, tech specs, quality, price, and raving customers’ reviews. A must-have item if you travel far and wide, and even if you do not!

Now that we saw each best reverse osmosis system in its category, it is time to talk things in-depth when it comes to this particular tech and the needs it may meet. For you to calibrate your expectations correctly and make an educated decision regarding reverse osmosis filters, here are the main things to know!

What is Reverse Osmosis Technology?

Reverse Osmosis – or RO systems – utilizes a semipermeable membrane to purify the water by stripping it of its impurities and contaminants (of a certain size). The resulting water that goes through that membrane (or membranes) is pure and clean. RO systems, just as you saw when you read the reverse osmosis system reviews above, can successfully remove a very high number of impurities and contaminants, including some viruses and bacteria as well, and also salt from saltwater. 

When water goes through a reverse osmosis water system, it leaves behind all impurities, salt, and minerals. It is what specialists call “permeate” or “product water”, although it is pure water nonetheless. The other water stream – the one containing the left-behind impurities – goes by the name of wastewater. There are multiple solutions to manage the wasted water and you should buy the best reverse osmosis system that best fits your needs:

  • The wastewater goes straight to the drain;
  • A reverse osmosis system sends it back into the main water supply;
  • Almost any RO device can recycle it through the system to save it for plants or washing your pavement.

When you read about the waste/water ratio on our reviews above – although we explained this when we discussed specific under sink reverse osmosis water filters – you should understand that for one gallon of pure water you consume a gallon of water (that the system wastes). The ideal ratio is 1:1, but given the tech advancements of today, a 3:1 waste/water ratio is still a good deal. The permeated water stream goes one way, while the wastewater goes another way.

Are Reverse Osmosis Systems Healthy for Us?

Nevertheless, RO systems receive criticism because the pure water is minerally dead, considering that tap water does contain healthy minerals. For this reason, an RO system comes with a re-mineralization and alkalization system, which adds back the essential minerals we all need to ingest with our water. Some brands, as you already noticed above, are very mindful about the added minerals regarding their origin, quality, and concentrations.

How Many Reverse Osmosis Filtration Stages are Necessary?

Looking at the best reverse osmosis water filter in each of the three categories, you noticed that most products take pride in their great number of filtration stages. Most experts agree that a minimum of 4-5 stages works well for city tap water to ensure its purity and your health benefits. In the case of contaminated water, the more stages a system has, the better. If you want to properly choose and size a water filtration system for your home, check out our guide on how water filters work and what the best filtration technologies are for your specific needs.

Do You Need a Permeate Pump and Other Accessories with Your RO System?

A permeate pump – which is different from an electric pump, mind you – increases the RO system’s efficiency without putting extra pressure on the filter or the process. Moreover, a permeate pump also makes the RO system more eco-friendly and more economical, as it makes the filtration system more productive. In short, the answer is yes – if you have the possibility to add a permeate pump to your reverse osmosis water filter, you should consider it.

Speaking of accessories, UV light is efficient in treating the water against bacteria and other dangerous contaminants. Some of the systems we detailed above work together with added UV lights.

What Else Should You Know about Reverse Osmosis Water Filters?

The most important lesson to take from this article chapter is that you should test your water with the help of professionals before buying an RO system or a traditional whole house water filter for that matter. When you learn about the impurities and contaminants in your water, you are able to make better decisions regarding the type and size of the water filter your home, office, or business needs.

Some go for classic whole house water filters to put their minds at ease, others prefer under sink RO systems for mineral tap water, while others (who move around a lot) simply love to pack their portable reverse osmosis system and set course for their next destination.

What Is Your Favorite Best Reverse Osmosis System?

Large families/homes, buildings, and businesses opt for whole house water filtration (with or without reverse osmosis). Are you a fan of such product or do you prefer the simpler route of installing an under sink RO filter for great-tasting, healthy water, beverages, and foods? Let us know in the comment section if you already use an RO system at home and how you feel about it!
