I have using pureit classic from last 4 years but it performance not fullfil my expectations, water purifying very slow and cartridge amount very high, I have to pay Approx 1200 rupees for exchange cartridge for 3000 litre capacity . Purify machine plastic quality is very low which is not unbreakable plastic. Water capacity mention 23 litre means 13 litre storage Purify water & 10 litre unpurify water but problem is that if water purifying is very slow than how can get 23 litre Purify water in whole day? After sale service very poor & 72 hours you have to wait for service engineer to exchange cartridge, means till 72 hours you will have to no drinking water but I have to pay extra charges Rs. 250 for engineer to get/confirm fault or slowness reason & Rs. 50 for exchange cartridge and both amount is extra amount from original cost, I will not recommend puriit classic 23 litre for any one.
