We brought this aquagruard long back. For a year or 2 the product will be good. After that we need to change the filter every 3 or 4 months. If we call customer care for service. They will only after 2 days. They will say us to change the water and use. They insist us to use well water. Do not use corporation water. Beforeit only filter is getting dirt. What ever water we use the filter gets dirt every 6 month.
So we stopped using the product itself. Because the filter cost is also high.
I recommand to use some other better product.
