I used this to replace the last filter in my 5 stage reverse osmosis system. It was easy to install, there was no noticeable residue when flushed, and my TDS meter always showed normal readings when I tested the water. The only problem is that the OD is slightly smaller than the stock filter so it doesn't fit snugly in the plastic clip on top of the RO unit. This is not a problem in my application as it is a permanently installed household unit.
