Installed April 27th. by may 27th the flow was slowing down. not suspecting the filter I checked everything else, all ok removed filter to find it had failed internally. It's not my water, it enters the house and goes through chlorine treatment, a double cartridge 10 micron filter, a large backwashing filter, then for drinking water two charcoal filters, a 0.5 micron filter and a drinking water combination filter, then it goes to the refrigerator. I don't  even need the filter and it still failed. Don't buy!
