Reverse Osmosis (RO) water purification systems are one of the best ways to get pure water at home for relatively little hassle. These systems can be installed under the kitchen sink and are especially popular because they are extremely good at removing waste thanks to their multilevel approach to water filtration.

Through a series of filters and a membrane, as much as 99% of contaminants can be removed from your drinking water before exiting a faucet as supremely purified water.

The ease of installing an RO system at home and the relative low cost associated with purchasing one combined with the effectiveness of these systems make them ideal for those looking to purify drinking water. Keep in mind that a RO system works best when limited to one water source. In other words, this method is not necessarily best used to treat a whole home water system. The process involves some time and the demands of water pressure in the home would likely exceed the capability of the RO system.

For those looking for clean drinking water at home for a low cost however, an RO system may be exactly what you need. We will highlight four of our favorite picks for home Reverse Osmosis (RO) systems.

What can an RO system remove from drinking water?

RO can effectively remove everything from carbon particulate to chlorine. A few examples of other contaminants treated by RO systems are Flouride, Arsenic, volatile organic chemicals (VOCs), like formaldehyde, as well as salt, lead, and radium. However, although able to eliminate the occasional bacteria, these systems should not be counted on to remove most bacteria and viruses.

Other Benefits of an RO System

The benefits of using a reverse osmosis filtration system in your home are many.

As stated before these incredible systems can remove myriad impurities that pose a variety of health threats. Each individual water source will benefit from a RO system differently depending on which impurities are being treated. Some of the health benefits observed as a result of reverse osmosis filtration include: improved gastrointestinal health,  stabilized blood pressure and decreased infertility in some people.

Obviously, these health problems have more factors than the patient’s drinking water, and we are not making medical claims. However, these RO systems remove harmful toxins and have been linked to a positive effect on the health of many people suffering from a variety of ailments.

The remineralization process used in many RO systems also ensures that you receive minerals that your body needs in the recommended amounts, taking the guesswork out of making your drinking water healthy and safe.

RO systems are not only reliable ways to get healthy drinking water that lacks dangerous contaminants, but they improve the taste and smell of water as well, often by adding in important minerals and balancing pH in the water that would have previously had an unpleasant taste. Many of the customers who use the systems we recommend here commented on the vast improvement to the taste and smell of their water thanks to the multi level approach used in reverse osmosis, which removes even dissolved substances out of drinking water.

Other Features that Matter

When it comes to reverse osmosis filters for drinking water, here are a handful of additional features that are important to consider when shopping for a system.

  1. Stages of filtration: The way that RO works is through levels or stages of filtration whereby impurities are removed by increasingly smaller filtration. In other words, the largest particles are removed first and then the stages of filtration progress to remove even the tiniest bits of contaminants which have been dissolved in the water. All of the systems on our list have at least five stages of filtration and as many as seven. When shopping around be sure to look into the percentage at which the company guarantees impurities are removed, and how many stages the filter uses to purify the water.
  2. Length of filter life: Check with the manufacturer of the particular model you go with to determine the optimal time to change the filters. Many can go for six months or even a year, though are usually measured by the gallon, as in “change every 300 gallons”. You will probably have to determine how many gallons of water you consume on a daily basis in order to establish a schedule for changing the filters.
  3. Included faucet/Quality of faucet: You should also keep in mind which models include a faucet and the quality thereof. Most of the reviews of the RO systems we recommended here were very positive about the faucets included. Most are stainless steel or brushed nickel and look sharp and classic in just about any kitchen. Occasionally a reviewer is unhappy with the faucet, though overall the vast majority of consumers are satisfied with every feature, faucet hardware included.
  4. Warranty: The warranty that is offered with the purchase of an RO system is significant. Most of the systems on our list have warrantees of at least one year, and many for longer. It may be worth a phone call to the manufacturer to ask some questions about what exactly is included in the warranty before you ever need to use it. Obviously the hope would be that with an excellent product functioning properly you would never have need of a warranty but having one provides a lot of peace of mind and can save you money and time in the event that an issue comes up with your RO system. You could also look into a company like American Home Shield which will actually insure your appliances and replace them whenever they malfunction.


When all is said and done, the concept of reverse osmosis filtration is both incredible and effective but it can also prove confusing. After careful consideration of how each of these systems works and what specific features are most important to you, this list offers some of the very best options for your drinking water.

Having pure, healthy drinking water is something that all of us, literally can’t live without.

We think that the process of choosing a RO filter for your home is an important one but doesn’t have to be extremely complex. Hopefully these four systems and the information provided has helped and you are well on your way to a purchase you can feel good about in more ways than one.
