Why we choose to write on this

The reverse osmosis system gained the public attention back on the start of the past decade. Since then, many households and commercial industries have adapted the technology to produce pure and clean drinking water in an affordable way.

However, many people still misunderstood the technology, and are hesitant to purchase it. With so many types and brands are available on the market, making a purchase decision can sometimes be a daunting task, and those are the reasons we are compiling this guide.

Why You should Trust Us

With the internet flooded with information, reviews, and guides, it is understandable for you to question the legitimacy of our guide.

I am a real person of the medical profession and the real passion for health. With technology and science as my hobby, I try to combine both to help people achieve better health through technology.

What Is Reverse Osmosis System?

Before we can understand reverse osmosis, and its importance, we must first understand the term ‘osmosis’ itself.

Understanding Osmosis

Osmosis is a natural phenomenon, and in fact, one of the most important processes happening in our environment. By definition, osmosis is a spontaneous movement of a liquid substance through a cellular, semi-permeable membrane. The movement occurs from a place with a higher concentration to a place with a lower concentration.

Sounds confusing? Let us explain by an example. One of, if not the most important occurrence of osmosis in nature is how plant roots absorb water from the soil.

The Reverse Osmosis

When natural osmosis movements can only happen from a higher concentration to a lower concentration, the reverse osmosis allows the reverse direction. By applying some form of energy, we can reverse the osmosis process so that the lower concentrated substance can move towards the higher concentrated one.

Why Is It Important

The reverse osmosis allows pure water to be separated from contaminants such as dissolved salts, pyrogens, bacteria, and organics, and other unwanted minerals. This process will be impossible with natural osmotic movements. Reverse osmosis system ‘push’ the pure water through the reverse osmosis membrane, while leaving the contaminants behind, and you’ll get a clean, pure water as the end product.

Benefits of Drinking Reverse Osmosis Water

Drinking more water is always a smart health decision! However, will drinking a pure, reverse osmosis water bring more benefits for you?

Here are some key facts you might want to know about drinking reverse osmosis water:

Health: Removal of Contaminants

There are a lot of microscopic contaminants that are unseen in your average drinking water. Yet, they can bring an extremely harmful effect to your body.

Here are some of the notable and dangerous contaminants that will be removed by a reverse osmotic system:

cryptosporidium (cyst)
Nitrates and nitries

Economics: Eliminating the Needs For Bottled Water

A lot of us are afraid of the contaminants in our tap water, or simply don’t like the taste of it. Those two could be the major cause why you’re buying bottled water all the time.

Bottled water is an expensive liability in the long run, not to mention piling up the plastic wastes is bad for the environment

A reverse osmosis system can justify the long-term cost, and will be a better overall investment economic-wise.

In the U.S. alone, Americans spent more than $14 billion on bottled water in 2015.

Taste: It Tastes Better Both for Drinking and Cooking

When your tap water is impure, it will definitely affect the taste of the food you cook with.

Reverse osmosis water simply tastes better, including when you make your coffee or tea with it.

Many testimonies and studies pointed the major difference in both the taste and appearance of reverse osmosis water.

Maintaining a Reverse Osmosis System

Regular maintenance of your reverse osmosis system will be necessary to ensure its longevity. Here are some of the necessary maintenance procedures you can do:

Changing Filters:

There are generally three major categories of reverse osmosis systems: three, four, or five stage filters. Check your respective owner’s manual for the product to get a clear picture of how many filters you have, and the exact type and which filter belong to each stage.

Here are the types of filter, and a general rule of thumb for maintaining each of them:

    • Carbon Filter

Carbon filters should generally be replaced once in a year.

    • Sediment Filter

Sediment filters should also be changed every 12-months.

    • Polishing Filter

Commonly the final stage of filters. The lifetime expectancy for polishing filters usually varies between brands, but commonly they should be changed every 6 to 9 months.

    • Reverse Osmosis Membrane

The semi-permeable membrane is the core of the whole system. The membrane usually will need to be changed every 2 or 3 years, depending on brands and types of the product.

Annual Cleaning and Maintenance:

With the filters commonly need to be changed every year, it would also be a good time to do a thorough cleaning and sanitization.

In general, here are the steps you should do:

    • Shut off all the valves completely
    • Make sure all of the water inside are dispensed
    • Remove the filters and the reverse osmosis membrane from their respective housings
    • Screw the housings back in place
    • Pour 1 cup of hydrogen peroxide into stage one housing
    • Reattach all connections
    • Turn the main valve back on, and let the system run for at least two cycles
    • Install the new filter replacements
    • Fill the tank back up with water, and drain one more time to eliminate excess hydrogen peroxide

Ultimate Buying Guideline


After we have discussed the technology behind reverse osmosis systems, as well as some of the notable products we recommended.

To make a better purchase decision, here are a few important things you might want to consider:

Waste water ratio

Being essentially a filter, all reverse osmosis system will produce waste water. Technically, a reverse osmosis system can achieve ‘zero waste’ by circulating the waste back into the system with some form of an electric pump. This technique, however, will wear down the filters more quickly, increasing your long-term cost.

As a general rule of thumb, a good reverse osmosis system should have a maximum of 4:1 waste water ratio or less, meaning for every 4 gallons wasted, you will get 1 gallon of purified water.

Filter Stages

Generally, the more filter stages a reverse osmosis system has, the better the purified water quality will be.

However, with every filter needing a regular replacement, the more filter you have in your system, the higher the long-term costs will be.

Compatibility with Your Household

Installing a reverse osmosis system will disrupt your existing setup. Before making your purchase, make sure that the product will not require a major renovation or overhaul, and will be compatible with your existing setup.

FAQ (Frequently Asked Question)

1. Is Reverse Osmosis a Distiller?

Ans. Although the principles between both are similar, with the same purpose of reducing dissolved solids from water, the process are different. Distillers use temperature to condense and capture the water, with impurities left behind in the boiling chamber.Reverse osmosis, on the other hand, relies on semipermeable filters.

2. Distilled water vs reverse osmosis water, which one is better?

Ans. With the principle of using hot temperature to ‘filter’ the water, distillers won’t do a good job with chemicals and contaminants with a low boiling point.However, for the most part, both water produced are very pure.

3. Reverse osmosis unit wastes a lot of water

Ans. As we’ve also discussed above in our Ultimate Buying Guideline Section, reverse osmosis systems indeed will have waste water. However, based on many studies, the costs, in the long run, assuming you are using a good reverse osmosis product, is hardly noticeable.

4. Can the reverse osmosis unit be hooked to my refrigerator

Ans. Depending on your manufacturer, your reverse osmosis system might connect to your refrigerator or icemaker with a tube, commonly 1/4″,

5. How long will a typical reverse osmosis system last?

Ans. If you maintain it regularly (see our maintenance section above), your system can last 3 to 5 years.

6. Is it true that reverse osmosis membrane won’t filter chlorine?

Ans. It’s true because it’s not the job of the reverse osmosis membrane. Chlorine is filtered by carbon filters often found in the first stages of the filters.

7. Do reverse osmosis units need electricity?

Ans. No, unless you add additional electric pump or ultraviolet lamp.Is it true that reverse osmosis systems remove minerals essential to our health?

8. It’s true, but it’s more of a matter of tastes rather than health issues.

Ans. Based on numerous studies and medical journals, the minerals in water are inorganic and are rarely used by our body.However, a lot of people are used to the taste of mineralized water. Newer reverse osmosis system re-mineralizes the water for tastes purpose.

9. How is reverse osmosis water compared to bottled water?

Enter your text here...

Ans. At the very least, reverse osmosis water as just as good as bottled water. More advanced reverse osmosis systems have also been proven to produce even purer water than bottled ones.

10. What contaminants are reduced or eliminated by reverse osmosis processes?

Ans. There are more than 1,000 contaminants and pollutants proofed to be filtered by reverse osmosis systems. Among them are arsenic, barium, lead, fluoride, and selenium. All of them are potentially dangerous for humans.
