Best RO Water Purifier in India

Water is life and the water we drink has a direct impact on our health. So, it is needless to say that we must make an informed decision while selecting a water purifier for our home.

While there are different types of water purifiers available in the market, RO water purifiers that use the Reverse Osmosis purification method is one of the most popular and effective filtration methods because it is capable of removing a wide range of impurities such as heavy metals, arsenic, fluoride, etc. from the water.

RO water purifiers are especially recommended for those who use underground water sources such as borewell water that has high TDS (Total Dissolved Solids) levels.

But, before you move on to choose an RO water purifier for your home or office, it is important to consider a few important factors such as the capacity of the purifier, power supply, TDS controller, quality of RO membrane, the presence of additional filters, etc.

How to Choose an RO Water Purifier?

1. TDS Level of your water

Before you buy an RO water purifier, it is important to ascertain the level of Total Dissolved Solids (TDS) in the water you drink. TDS includes salts, minerals, metals and organic substances. Water with a higher level of TDS is harder compared to water with low TDS level.

2. Quality of the RO Membrane

This is the most important component of an RO Water purifier that determines the efficiency of the purifier. The pore size of the membrane plays an important role infiltration of impurities. The pore sizes of RO membranes range from 0.0001 to 0.001 microns. RO membranes can filter out organic salts and metallic ions of mercury, lead, fluoride, etc. from the water.

3. TDS Controller

This is yet another essential component of the RO water purifier that adjusts the level of TDS in the filtered water. Because RO water purifiers remove heavy metals and salts during the filtration process it also removes essential minerals from the water to a large extent. A TDS controller helps to retain some of those essential minerals in the water.

4. Additional Filters

Most RO water purifiers come with a range of pre-filter and filters that ensures improved filtration.

  • Sediment Pre-Filter – This filter is present at the inlet of the system and it helps to remove sediments and chemicals from the water. It also enhances the life of the RO membrane.
  • Activated Carbon Pre-Filter – Activated carbon filter removes dissolved solids and chemicals from the water efficiently.
  • UV Filter – Some high-end RO water purifiers also feature UV filter that kills any microorganisms present in the water.
  • Carbon Post – Filter – This filter removes any unpleasant odor from the water and improves its taste.

5. Pressure Enhancing Pump

Most RO water purifiers use a pressure enhancing pump for the RO filter to work properly in case the pressure of the incoming water is not high enough. While some purifiers come with a built-in pump, in other cases a pump can also be added separately to improve inlet water pressure.

6. Storage Capacity

Most standard water purifiers come with a storage tank that stores the water after purification. A purifier with a 4 to 7 liters capacity storage tank is good enough for a small family.

7. Power Supply

Because RO water purifiers require a pressure enhancing pump to function, therefore they cannot work without electricity. You should only opt for RO water purifier if you can provide constant power supply to your purifier.
