Types of Water Purifiers

Gravity-Based Water Purifier

Gravity Based Water Purifiers works on the principle of gravity. They are suitable for low TDS water or if your budget is low as they are cheaper as compared to other types. It doesn’t utilise electricity for purification. That’s why they are popular in the area who suffers power cut and electricity issues.

  • For the purification process, it uses an activated carbon filter and ultrafiltration (UF) membrane for removing impurities from the water.
  • It’s a different kind of water purifier that doesn’t need a power supply to work.
  • It has two compartments, one for raw water and second where pure water gets stored.

RO Water Purifiers

The RO (Reverse Osmosis) water filter requires electricity to operate. It is the only water purification system that can remove the TDS in water. In this process, water passes via a semi-permeable membrane to remove all the dissolved impurities. But some of the RO water purifiers waste a lot of water.

  • They are known to remove nitrates, sodium, arsenic, copper and lead, some organic chemicals and the municipal additive fluoride. However, they are not as useful as UV filters against viruses and bacteria.
  • These are essential in areas where the contamination level is high.

UV Purifiers

These purifiers use ultraviolet radiation technology to purify water by deactivating water-borne, disease-causing organisms. It can’t work with dirt or turbid water as the dust particles in the water can shield the bacteria against the powerful UV rays.

  •  The UV water purifiers can’t remove the dissolved salts present in the water. So, choose the UV water purifier only when you receive water from a municipality or public water supply.

How to Choose The Best Water Purifier?

Buying a water purifier is actually a health investment. Health is wealth so, we recommend you buy a quality water purifier that is capable of keeping you & your family healthy. Regular water contains harmful substances that can cause malfunctions in human body. A water purifier can remove viruses and other microorganisms from direct source of water like tap or borewell.

You should buy a water purifier which can last for a long time and prevents wastage of water and electricity.

TDS Controller

TDS stands for Total Dissolved Solids that represents the total amount of dissolved substances in water that include minerals, salts, metals, cations, and anions. If the TDS is less than 300 mg/litre, the water is considered as best for drinking.

A TDS Controller lessens the TDS level in the water coming out of the RO Membrane. It decreases the hardness of water by 90%.

Water Quality

Type of water purifier corresponds to the water supply in your area. You must get water checked at home before picking a purifier. If the water supply you home has high TDS and is hard, then go for RO water purifier. While if water has low TDS, a multi-level carbon filter will do the necessary purification.

  • If you live in metro cities, pick a high-grade water purifier that has all three purification system RO+UV+UF and a TDS controller too since they’re known for there ultra purification capability.
  • For the three-tier cities and town in India, RO+UV is ideal enough. However, if you wish you can always go for RO+UF+UV+TDS controller if your budget allows as they’re always the best.

Below table will help you out to determine whether you need UF, UV or an RO water purifier.

Above 500 ppmGoodUV+RO water purifier with mineralizer
Above 500 ppmTurbid/MuddyUV+UF+RO water purifier with mineralizer
Above 2000 ppmNAwater isn’t fit for drinking

Storage Capacity

Generally, water purifiers have a capacity of 7-8 litres. This capacity works well for a family of 2-5 people. For a big family with 6-13 people, a purifier with 10-15 litres storage capacity is perfect.

An automatic water purifier is one right choice since in that you don’t need to do anything. When the water level goes down, it automatically starts filtering to fill the tank.


Every water purifier needs regular maintenance. At least once in a year, the cartridges need to be replaced. Some filters require six monthly maintenance as well.

Warranty and Certification

Always check the certifications of the water purifier you’re going to buy. It’ll help you identify a genuine and authentic quality & brand product. Choose a purifier from a trusted brand such as Kent grand, Blue Star or Eureka Forbes. Also, check the warranty of the product.

Frequently Asked Questions

1. What is the maintenance cost of water RO purifier?

All water purifiers require periodic maintenance, consumable parts like membrane and filters need to be replaced at regular intervals. Replacement of these filters assures the purity of water and maintains the efficiency and effectiveness of purifier.

Most reputed brands offer standard AMC (annual maintenance cost) packages. These packages generally cover all consumable, electrical parts and periodic servicing.
Usually, these packages start from RS. 4,000 and can go up to RS. 8,000 depending on the brand and water purifier model.

2. Which is better ABS plastic or Stainless steel tank?

Both are good; however ABS plastic is lighter than steel. Secondly, ABS plastic is more durable than steel and non-toxic. It can withstand a high-temperature range. It doesn’t require as much maintenance needed by the steel tank.
Hence ABS plastic tanks are preferable to a stainless steel storage tank.
