My friend suggested to me non-electrical water purifier in Low Budget. I purchased this product Rs. 1500. I am using Kent Gold Optima 10 litre water purifier. I am fully satisfied with product. It is sufficient for 3-4 member. It is portable & easy-to-use product. Its look also attractive compare with other water purifiers. It is light weighted product. Sometime it working very slow, if you clean it monthly then no problem. I also suggested to my friends. Kent is a reliable product.
