I purchased this tata swach from official tata website because earlier when I purchased it from amazon it broke down within 5 days thanks to amazon 10 days return policy I was able to return it , but I again purchased it from official website on december 2020, since then I have been using this so I divide review between pros and cons.
Pros:
1.simple gravity based mechanism.
2.non electric process.
3.good capacity for single person or small family.
4.inexpensive.
Cons:
The only con I found during my usage is that in some parts of the purifier tata compromised with quality it seems delicate there.
In the end I conclude by saying just take care of the purifier it will take goode care of you.
