Buyer’s Guide for Reverse Osmosis Water Purifier in India

For consumers, there are no other water filtration technologies that can come close to Reverse Osmosis technology in term of the numbers of contaminants it can filter out and the quality of water it can produce.

So let us explore, how to choose best RO purifier in the market.

What Is A Reverse Osmosis Filtering System?

There are several things you should be aware of when you’re looking to buy a reverse osmosis water filtering system among many other water treatment technologies for household use. Most household owners heard of this kind of system, but they don’t really know what it is and how it works. In the following section, we will explain the most common terms you’ll encounter when looking for a reverse osmosis water filtering system, and how this type of system works.

Suggested read: What are RO water filters?

What are the standard features of RO water purifier?

Here, we will list some of the essential features and specifications of reverse osmosis devices that you will encounter:

1. Semi-Permeable Membrane

This piece is probably a vital element for every reverse osmosis system. As the name indicates, the membrane stops some particles before the water reaches your tap. Thus, you receive water filtrated from the contaminants.

2. Filters

The RO system filters the water at various stages to provide the optimal quality of your usable water. The filters have the task to remove dissolved salts, dissolved organic substances, and micro, fine particles water. A standard system includes the following filters:

  • Sand Filter
  • Carbon Filter
  • Cartridge Filter
  • Membrane Filter (Listed above)

3. High-Pressure Pump

This feature is optional. As we mentioned in the previous section, your water pressure could benefit from a reverse osmosis system, which has this component. The pressure pump will not only increase the flow, but it will also assist your RO system in performing adequately over a long time.

4 .Compact

Although a reverse osmosis system may take up space under your sink, it comes as a compact unit considering the weight of the mission it has. A standard RO system contains a three-dimensional configuration of modules to minimize the space it needs. As a compact filter, you may also want to consider a top-notch under sink water filter.

5. Simple Operation

A great advantage of RO systems is that they do not require your assistance to function because they are fully automatic. After you install them, they will perform the process with ease. Don’t forget that they also need to undergo regular maintenance, however.

6. Voltage

Standard 120V 3-prong plugs are compatible with RO systems.

7. Alkaline Re-Mineralizer

Another optional feature that we mentioned. It makes sure that the healthy minerals remain in the water that the line supplies you with. That way, you will stop worrying if reverse osmosis water is good for you.

8. Storage Tank

It holds about 3 gallons of water. Without enough water in the tank, the RO system would not be able to function.

9. Cold Water Valve

Takes the water supplied from a well or a treated municipal source.

10. Shut-off Valve

Prevents the waste of water when the storage tank is full. It stops the water from going into the tank when it detects that the limit has been reached.

What to Consider When Buying a RO Water Purifier?

Here are some things you should know before you purchase a RO purifier system:

1. What is the storage capacity?

The reverse osmosis system should go in the cabinet under the sink. Note that such a device requires quite a bit of space, which means you may need to dispose of your bin. Besides the pre-filters and the reverse osmosis components, there should be enough space for the tank. A limited space would not be suitable for a reverse osmosis system.

2. What is the water pressure for inlet pipe?

These devices do not function properly if the pressure is below 40PSI. There is a chance that you might be able to increase the pressure of your waterline with a booster pump. Some reverse osmosis systems come in pumped (with a booster pump), and others come without a pump. Note that if the water pressure cannot go up even with a pump, then a reverse osmosis system will not be suitable for your house.

3. How to make use of waste water?

One of the primary concerns with reverse osmosis systems is that they consume vast amounts of water. The water that carries the contaminants to the drain is more than the water that is filtered to become suitable for usage. This factor is significant because some people might not have the option of wastewater.

4. What is your water source?

If you live in an urban area, a treated city source is probably providing you with water in your house. The water in further suburban regions might be coming from a well. Check the descriptions of reverse osmosis systems because some might be more suitable for filtering the contaminants from well water more than others.

5. Does it come with a re-mineralization?

There is a tendency in reverse osmosis systems to be so diligent in filtering water that they also remove some of the healthy elements from the water. Therefore, you might consider purchasing a unit that has an alkaline re-mineralizer filter that re-introduces the beneficial minerals back to your water.

6. How easy to get replacement filters?

For any water filtering unit to perform the way it did when you purchased it, you will need to do regular maintenance work. Some people find the task to maintain an RO system to shape a tiring job because of the multi-staged filtering process. The reverse osmosis system has more than one filter. You need to keep track of every replacement you make because some filters require more frequent changes than others. This detail also adds more to the cost of a single system.

Common Questions on RO Water Purifiers in India

What substances do reverse osmosis systems remove?

RO systems have several filters, each responsible for eliminating specific contaminants. Amongst those are lead, copper, magnesium, sand, fluoride. They are all harmful to your health and may lead to issues and malfunctions in your body. Since water is so essential in our lives, the RO system has a crucial task in removing the elements which are not beneficial for us.

Does the RO system have an impact on the environment?

The most prominent environmental impact of RO systems comes from water waste issues. For every 2 gallons of purified water, 8 gallons go into the water waste system. Not only that this increases the cost of your water bills, but it also seems like a lot of water that could come to use. A simple solution is to use the wasted water for other purposes. At the same time, an RO system prevents a lot of people from purchasing tons of bottled water every year.

Does the RO system pose any risks to your health?

While the RO system removes harmful particles, it also takes away some essential elements that enter our bodies through the water daily. Calcium and magnesium are particularly beneficial for the bones, as well as some other minerals that find a place in the water. Thus, the debate over the advantages and disadvantages of RO systems continues. However, the device itself does not create new risks to your health.

Is a reverse osmosis system like a distiller?

They are different devices, with differing working processes, but similar ending results. As you already know, the RO system uses a semi-permeable membrane to filter the water. The distiller boils the water and then condenses the steam to purify it. A big deal of the contaminants remain in the unit and are not released with the water you will drink.

How long will a reverse osmosis system last?

As long as you perform regular and diligent maintenance, the unit should last you virtually forever. Remember to replace each of the filters as required to enjoy the better taste of the water.

Over to You

RO water purifiers offer one of the most advanced ways of producing clean water for your household. Recent technological advancements lead to an increase in efficiency and quality, so new RO systems produce water of similar quality to bottled water.
