I bought this product during Oct 2010 and exactly after 1 year 3 months the product was not working at all.
When I called customer care they said the life time of this main filter is 1 year and it will not work after that.
To repair the same its going to cost me around 1/3rd of the product.
When the complete product is going to work for around 1 year then what is use of buying this product? If a products maintenance is low then we mention it as a good product else its of no use.
My suggestion is better not to buy this product at all.
Thanks,
Naresh
