I am using this purifier since 3 months, I found this product is very coolz and nothing problem with this one.
After purchase I inspected every part of this one, It is so difficult to cleaning but assembly of this filter is very fine and accurate. Machenism is to easy to use and chage the parts.
If you try to clean very dirty and muddy water, It does work very well and get pure transparent clean water.
I bought just for Rs. 1525 only in retail market. I bought also an additional germ kill kit for change if it will not work after 3000 Liter.
I recommend to all to purchage it if you need.
