There are several modern techniques to filter impure water. Reverse Osmosis (RO) is one of them. It is a water purification process that helps in removing contaminants and impurities from unfiltered water. In this technique, a semi-permeable membrane is used with the objective of removing undesired molecules, ions and different kinds of particles that make the water impure and unfit for any kind of consumption.

The fresh water produced through this process is called permeate and the amount that remains unused is referred to as brine. A partially permeable membrane consists of small-sized pores that block the access of contaminants but facilitate the movement of water molecules from one direction to another. In the reverse osmosis process, contaminants are blocked from getting inside the part of the membrane which has a lesser concentration of water. When reverse osmosis is applied on a bottle containing salt water, the salt residue remains in the bottle and clean water comes out of the bottle. Here are a few water filters that use reverse osmosis process to purify the drinking water.

Here Is The List Of The Best Reverse Osmosis Systems With Our Expert Review:

The Benefits of Osmosis Water Filter

Are you tired of buying bottled water? A reverse osmosis system ensures there is quality water in your home fit for your drinking and cooking needs. With the best reverse osmosis system, you can filter out more than a thousand harmful contaminants from your water.

Additionally, you will easily remove foul taste and odor from the water. In this section of the article, we’d like to share with you some of the benefits of using a reverse osmosis system.

Better Taste

As earlier mentioned, a reverse osmosis water system removes debris and chemicals from any water source, which makes it taste better. It’s not magic – it’s as a result of the passage of water through as much as three to seven filtration chambers in a reverse osmosis purifier.

Clean Water

With the best reverse osmosis system, you can remove many harmful aliens from your water. You’ll have rest of mind knowing that you don’t drink contaminated water.  The contaminants that are removed by a reverse osmosis system include but are not limited to lead, chlorine, taste, odor, sediment, etc. to mention a few.

Low Energy Usage

Again, a reverse osmosis water system uses less energy when compared to similar water filtration systems. A reverse osmosis machine is ideal if you want to save on energy and still enjoy quality water. However, if you have a reverse osmosis filter installed in many of the faucets in your home, your energy consumption will increase.

At this point, we suggest a faucet water filter which uses no energy at all.

Saves Space

Do you want to buy a reverse osmosis water filter but you are concerned about installation space? Don’t worry, most RO water purifiers are very compact and can fit under your sink. The image below shows the space saving design of a popular reverse osmosis water filter

Low Cost Of Maintenance

Maintaining a reverse osmosis system is as simple as ABC. Generally, a reverse osmosis machine requires a change of the filters at least once in 6 months. You’ll only need to spend on purchasing the filter but not on anything else.

Multi-stage Filtration

The best reverse osmosis system for well water offers up to 7-stages of filtration. Each stage removes different contaminants from your water and improves the quality and taste. The lowest number of stages you should go for is 3. Anything below it won’t be worth spending money.

Saves Cost

Save the money you spend on bottled water with the best reverse osmosis system. Reverse osmosis machine eliminates or lessens the amount you spend on bottled water.

Reduces Plastic Wastes

Water from reverse osmosis water filter is as good as bottled water. Installing Ro water purifier in your home or office reduce the number of plastic waste in the environment. In addition to that, it saves you a lot of money in the long run.

Imagine buying bottled water for a household of 6 or 7 not forgeting the pets!

Easy To Install

You can easily install a reverse osmosis system yourself after reading the instruction manual – no need for professionals. There are also tons of installation videos on YouTube aimed at guiding you in installing your reverse osmosis water system.

Best Reverse Osmosis System Buying Guide:

Now, that you know the benefits of having a reverse osmosis system for home, you need to know the factors to consider before buying one. Read this buying guide thoroughly to make sure you buy a unit that will meet your needs.

The first factor to consider is the cost.


Here on WaterFilterIQ, we always advocate that you buy what you can afford. However, you shouldn’t sacrifice quality and performance on the altar of price. In the long run, you may end up spending more shipping back defective or low quality products.


Most reverse osmosis systems require a separate faucet to dispense the treated water. You can easily change the faucet in your kitchen to a RO faucet without losing the finish, style, and color of your old faucet.

The non-air gap faucet is the common type of RO system faucet. There is a valve inside the non-air gap faucet that prevents the backward flow of water into the reverse osmosis tank.

Stages of filtration

The best reverse osmosis system usually has 3 to 7 stages of filtration. But, your water source will determine the number of filtration stage your RO system should have. Typically, well water and tap water are the most common sources of water.

Treatment plants treat the water they channel to homes. So, tap water logically contains fewer contaminants compared to well water. This is not always so as the water may be contaminated in the pipes.

If you live in an urban area with tap water, an RO water purifier with 3 to 5 stages of filtration should be your base system. Well, water, on the other hand, requires a reverse osmosis system with 6 to 7 stages of filtration since they are known to have high levels of contaminants.


Reverse osmosis machine uses water to clean the reverse osmosis membranes after filtering for a while. RO water purifiers generate wastewater in the course of purifying your water. Most reverse osmosis systems waste up to 4 gallons of water contaminated water for every gallon of purified water.

However, once the Ro system storage tank is filled, the system shuts down. The wasting of water is referred to as pure water to waste water ratio. Opt for the best reverse osmosis system with a low pure water to waste water ratio.

You might want to ask, are there no zero-water-loss reverse osmosis machines?

There are but they re-inject concentrated wastewater into the RO system feeding pipe. The best way to make your reverse osmosis machine more efficient is to connect it to a permeate pump.

Know Your Water Hardness Level

The best RO water purifiers for home does not soften water. So, if your incoming water has a hardness of up to 7 grains per gallon (GPG), consider a softener pre-treatment. This will preserve the life of your reverse osmosis system and membranes.

Installing a whole house water softener is arguably the best solution for this.

Water Pressure

Water pressure is a not-so-important factor that should be considered when buying a reverse osmosis system. The pressure of your water source forces the water through the RO membrane for purification and removal of contaminants.

Many of the RO water systems require a minimum water pressure of 60 psi to work effectively. Most water sources in homes meet this minimum water pressure.

However, if your water source pressure is less than 40 psi, consider buying a Ro system with a booster pump.

Reverse Osmosis System Production Rate

To understand this factor, you need to understand Ro membrane GPD (gallons per day) rating.

Generally, a reverse osmosis system operates efficiently within a pressure range of 40 to 100 psi. Within this pressure range, a reverse osmosis system generates 10 to 75 gallons (45 to 340 liters of water) per day.

Note that cold water cuts the production rate of RO systems by half. In addition to that, GPD ratings are issued to reverse osmosis systems under specific conditions – contaminants, temperature, and water.

We recommend an RO system with a GPD rating between 50 to 70. One gallon per hour with a water source pressure of 60 psi, therefore, a 50 GPD rating will serve a whole house adequately.

Filter Replacement

Buy an RO system with easy to replace filters. Don’t forget to check for the price of the filters before you buy the reverse osmosis unit. If you intend to buy replacement filter, buy only half a dozen or a pack of four.

We don’t advise buying in bulk since filters are only changed once or twice yearly. Filter manufacturers can produce better filters within that period of time.

Quality Certifications

Buy a reverse osmosis system with the best quality certifications. Again, check for the number of certifications –WQA (water quality association) and safety – TDS (total dissolved solids) reduction.

Pre-Filters, Carbon Blocks And Sediment Filter

To get the value of your money, buy a reverse osmosis machine with three pre-filters, one sediment, and two carbon blocks.

Here’s why!

Pre-filters, positioned above the RO membrane filters sand, and large deposits from the water source. Carbon blocks filter chlorine, odor and taste pollutants. Also, it prevents the RO system from wearing early due to chlorine.

Sometimes sediment pre-filters (which are cheaper than carbon) replace the second carbon block after the RO membrane. There is nothing wrong in that but, don’t buy a reverse osmosis system with two sediment pre-filters since carbon blocks filter contaminants better than sediment filters.


FAQ About Reverse Osmosis (RO Water Purifier)

Below we tried to answer the most common questions about using and managing a reverse osmosis system.

Q. What Is A Reverse Osmosis Filtering System?

A. Reverse osmosis (RO) is a filtration process which uses pressure to force water through a semi-permeable membrane. Osmosis occurs naturally in nature, but, this machine reverses the process of osmosis using energy. The RO membrane holds solute (solid) on one side and allows pure solvents (liquid) pass through to the other side.

Normally, osmosis is the movement of liquid from a region of low solute concentration, to a region of high solute concentration, without applying pressure, through a semi-permeable membrane. The reverse osmosis system does the exact opposite.

RO membranes consist of a thin polyamide layer (<200nm) on a polyethersulfone or polysulfone porous layer (50 microns) over a non-woven fabric sheet for support. This water purifier applies a pressure greater than the osmotic pressure to successfully reverse osmosis and purify water.

The semi-permeable membrane allows water to pass through it, but, retain solid particles. The membrane has a dense layer where separation occurs (the non-woven fabric).

Q. How Does A Reverse Osmosis System Work?

A. The water source flows through a sediment pre-filter placed above the RO membrane. It removes dirt and small particles in the water which flow to a carbon pre-filter. Also, the two carbon pre-filters filter organic contaminants: chlorine, taste and odor pollutants.

Next, the pre-filtered water enters the reverse osmosis semi-permeable membrane.

This membrane has a tight sheet-like filter which only allows water through whilst holding back dissolved solids, sodium, and contaminants like:

  • Lead
  • Arsenic
  • Asbestos
  • Calcium etc.

A reverse osmosis water system cleans its membrane with some of the water that passed through it. The contaminated water flows into kitchen drainpipes while the purified water collects in a storage tank until when needed.

This stored water is given a final push when you open the faucet by a post-carbon filter. The purified water in the tank is forced out of the tank by air pressure and goes through the second carbon filter. Assuredly, this final filter gives reverse osmosis water its taste and quality.

This description is for a 4-stage reverse osmosis machine. A 7-stage reverse osmosis system has other essential parts such as a flow control device, check valves and an automatic shutoff device.

Watch this video to understand how a Ro system works.

Q. What is the Best Reverse Osmosis System for Drinking Water?

A. Importantly, all reverse osmosis system membranes produce purified water, though they differ in features and sizes. The best RO water purifier for drinking water would depend on your water source. As we earlier mentioned, a 5-stage RO system works best with tap water. But, for well-water, you would need a 6 or 7-stage reverse osmosis machine

Q. RO Water Efficiency Ratio, Permeate Pump and an Air Gap Faucet Explained

A. Reverse osmosis system efficiency is the ratio of wasted water and pure water. A reverse osmosis machine with a ratio of 4:1 or lesser is considered efficient.

On the other hand, a reverse osmosis permeate pump is a simple device that utilizes the energy from the RO system wastewater to push pure water into the storage tank. A permeate pump isolates the tank from the Ro membrane, which acts as an atmospheric tank.

An air gap faucet creates a siphon break between itself, the Ro system, and the sink drain. Simply, the air gap system allows water to drop from one tube through the air, into another tube. So, when a sink drain is blocked, the air gap faucet pulls air instead of dirty water into the reverse osmosis system.

Pretty confusing, isn’t it? It’s not, really.

Q. What does Reverse Osmosis Remove from Water?

A. The best reverse osmosis system filters up to 1000 contaminants (particles and impurities) from different water sources such as:

  • Lead
  • Chlorine
  • Fluoride
  • Arsenic
  • Hormones
  • Asbestos
  • Sodium
  • Calcium
  • Bacteria
  • Virus
  • Chloramines

However, reverse osmosis system like the iSpring RCC7 6-Stage comes with a mineralization filter that restores healthy minerals. Some reverse osmosis systems also change the alkalinity of the water.

Q. How Pure is Reverse Osmosis Water?

A. A reverse osmosis system water is as pure as bottled water. Carbon filters in RO systems remove volatile chemicals, chloramines, etc.

Q. Is Reverse Osmosis Water bad for you?

A. No, reverse osmosis water is not bad for you, rather it’s very healthy for you as its free from contaminants and harmful microorganisms. Furthermore, it is good for pets – so they too can have access to clean water.

Q. Is Reverse Osmosis Water good for Plants?

A. Yes. If you decide to water your plants with reverse osmosis water, please go ahead.

Q. How To Install A Reverse Osmosis System?

A. Some reverse osmosis system must be installed by a licensed plumber while others come with an installation guide for you to install it yourself. Here is a list of the installation procedure:

  • Install the faucet on your sink.
  • Mount the faucet with someone holding it above the sink.
  • Install the angle valve and tubing right under the sink.
  • Fasten the valve with a drain saddle.
  • Install the RO components.
  • Install the RO unit.
  • Pre-fill the storage tank with water to check for leaks.
  • Connect the final tubing.
  • Start-up the system.

Find a more detailed explanation of a reverse osmosis system installation in the video below.

Q. How to Maintain a Reverse Osmosis Water System?

A. The pre and post filters of a reverse osmosis system must be changed regularly, at least after 6 months of usage. It is important to note that the frequency of changing the filter is dependent on the type of RO system and the level of contamination in the water.

Q. How to Change The Filters In Your Reverse Osmosis Water Filter?

A. This instruction is for a standard Ro system, ensure proper sanitation when changing your Ro drinking water filters and membranes. Follow this steps to replace your Ro system filters:

  • Turn off the water valve
  • Close the valve on the reverse osmosis system and the refrigerator or ice maker
  • Release pressure in the system by opening the faucet
  • Place a tray the sink to avoid spillage
  • Unscrew and remove the old filter
  • Remove the O-rings and
  • Place the new filter in the filter housing and tighten with your hand only.

Here’s a video that shows the replacement process.
