Dear Sir,
We are three person ( in total ) in my family.
We have purchased Pureit water Filter in August - 2008.After working of 9 months,having filtered appox.1,000 ltr. of water the battery expired ( Where as Co. claims that germ kill battery will filter 1,500 ltrs.of water ).
Any how, I got replaced the battery in May - 2009, and only after 3 months the battery expired again
( became red in total )...
