I purchased this product from a retailer 2 month back at Rs. 1600/-
they told me that the product will purify up to 1500 litre water, but in vain. while I was using the product(it didn’t purify water at it’s best, found huge amount of small sand in the water)i thought it might had some problem. so I took it to the retailer and he immediately changed the cartridge and took RS. 549/-
Still the problem remain same. waste of my money to buy such a 20 ltr water JAR.
