Hi I use a Puriet Marvella UV filter from past 1 yr & every 6 months I need t change the Germ kill kit. I was instructed that each Germ Kill kit would work to filter around 3000 lts before replacement. but here it is running out for 1300 lts only as we are a very small family & use it only for drinking.

can you pls re-validate & check if mine is a defective piece or your information of 3000 ltrs as marketed is wrong.
