I just bought the 3M water filter dispenser. Got cold water, room temperature and hot water. I don't know the filter good or not but I buy because of the brand 3M.
great..
but i kind of got a stupid qns..

lets say u empty the cool water tank straight, then water from supply pipe flows in again right, how long before it take to become cold again?

same for hot water..
