no instructions

We really like the filters BUT ------ There were NO INSTRUCTIONS on how to install the filters.. in what order.

My husband first installed the 1 micron, then the 20 and finally the carbon. The water tasted TERRIBLE. After a phone call, we found out that the carbon needed to be in the middle.

So then we had 1 micron, carbon and ended with the 20. The water was still TERRIBLE.

My husband did not realize the 20 had to be first. So after more talking he switched the 1 micron and the 20 micron around with the carbon in the middle. We got good water after that.

It just seemed very odd that the filters came with zero instructions on how to install. If he was not a carpenter and all around handy man, he also would not have known how to hook the filters up. Sometime this expensive deserves a HOW TO manual for installation.
