We have this puret manual 23L water purifier for padt 5years.I would say that there is nothing so special about this filter.
1) U have to put the water manually by yourself.
2) The filter sieve through which water is poured into the upper chamber gets clogged most of the time.
3) The upper hemispherical charcoal also gets clogged most of the time and requires cleaning every 10days for proper functioning.
4) Its very difficult to decipher when the germ kill kit is going to get finished.
5) germ kill kit is also costly.after buying 3germkill kit it almostt equalled the original price of the original filter.
6) Cleaning up process is also very hectic.
