Pureit purification system is a compact drinking water treatment product suitable for household use. It is developed by the Hindustan Unilever. The core of this system is its unique Germkill Battery Kit which consists of the Compact carbon trap, Germkill processor, and Polisher (shown in the figure). Each of these kits performs a certain treatment method.

==Technical specificationConstruction, operations and maintenance==
====Operation====
Firstly, water is poured to the system passing through the micro-fibre mesh which removes visible dirt. Furthermore, the compact carbon trap will remove additional dirt, some parasites and some pesticides. The water then flows into the germkill processor which uses a ‘sustained release chlorine technology’ to kill harmful bacteria and viruses. Finally, the water passes through the polisher which removes odour and improves water clarity.
Used, partly used, or unused germkill battery should not be thrown away together with garbage or put into fire, it should be disposed off safely with dry waste.

====Maintenance====
The Pureit consists of some moving parts which are more susceptible to breakage. A guarantee for the system is available. However, in case of breakage due to falling, the guarantee is no longer valid.
