The water has no more chlorine taste any longer which is nice. I'm not so sure that the system cleans the pipes as stated. I'm still seeing residue on my faucet in the guest bathroom, looks like the same type of build up as before. It doesn't seem to keep the shower heads clean as stated. Not sure maybe it takes more time. I've had the system for just a little over 6 months, time to change the filters lets see how that goes.
