A single TL cycle takes about 150 liters. RO will waste 600 liters of water to make 150 liters.
While FL takes about 60 liters. RO will waste 240 liters of water to make that 60 liters. It’ll be very slow and very expensive.
There ya go. Khada salt is even cheaper. I think if the water is hard then it’s better to go for front loader because it uses less water and ion exchanger should be able to fulfil it.
Flipkart brand won’t be as good as sam/LG but it’s sure will be better than onida. My reasoning was, flipkart has a humongous supply and service network for their own products. They sale more products than onida, motorola and other small brands combined together.
