If the TDS Total Diasolve Solids in your area is below 300 then it is a good purifier for you.
This doesn’t need any electicity .
And store upto 14 l water and purification time is not that bad .
You manually have to refill it.
It has a germ kill kit which needs to be replaced which can be done by you or thier customer service .
It had a indicater which will turn red when the germ kill kit needs to be replaced.
In my area TDS is 270 so I use this .
Overall this is good only if TDS is below 300 more than this and maybe it will not work or work I don’t know.
