I bought this filter when I shifted to new apartment. I used it for only 2 weeks then I notice water taste like acidic and smell like rotten fish, It took me 3-4 days to figure out that was caused by the filter. I barely drink water at home since I travel alot out. I am not sure why the filter life is very very less. I am not satisfied with the product due to the very short life of the filter. I will not recommend this product any one. I am not sure wheather its the issue with the filter I bought or with the company make.
