What is Tata Swach?

Tata Swach is a water purifier range made by Tata Chemicals. It is the second most popular water purifier range in the market.

Tata Swach employs Rice Husk Ash imbued with silver particles to purify water. RHA is manufactured by heating rice husk and it contains activated silica and carbon.

The Silver prevents bacterial growth and this process is elevated by the surface area provided by the incredibly small silver particles in order for the bacteria to have more area to react with silver.

The Tata Swach water purifier has 3 segments.

The first reservoir in the Tata Swach contains the untreated water and then, in the middle segment, is the bulb that stores the cartridge through which water is filtered, and then it is stored in the second reservoir.

There is a fuse system employed that alerts consumers regarding the change of cartridges.

Tata Swach is the most cost-efficient water purifier that uses silver technology. Its use of Rice Husk as a filter was a massively innovative move by Tata Chemicals and it was done in great spirit as it was also used for tsunami survivors.

It revolutionized the markets and taught a large chunk of the population the importance of purifying water and also served as an economical option for them to start using them.

What is Pureit?

Pureit is a range of water purifiers by Hindustan Unilever limited.

developed in 2004 and it remained in the development and testing phase until 2008, where it was nationalized into a proper range of products that have now been adopted by over 4.8 million consumers.

The Pureit has a four-stage process for purifying water. In the first stage, the dirt is removed using a microfiber mesh, and then the purifier moves on to using a compact carbon trap for parasites & pesticides,

and then in the penultimate stage, a germ-killing processor for bacteria & virus removal and a polisher for making the water tasteless and odorless.

The Pureit saves water as it is meant to be an eco-friendly product and also comes in both battery-operated and gravity-operated options.

Pureit has also launched RO water purifiers which are more expensive but also much more reliable.

The Pureit also removes heavy metals and other sediments but a lot of the natural taste of water still remains as it cannot remove salt from water.

Hindustan Unilever is a very renowned brand and this fact translated well in its water purifier range as well because Pureit has sold very well and accumulated a large consumer base.

Pureit has also advanced its technology and uses copper in its recent models as well.
