I now have placed this unit along with the AO Smith whole house water filtration unit inline before it in my motor coach and in my home. 2 systems with this and its sister product together. My water has 0.00 parts per million on the water meter straight out of any faucet. The water softener could only get my water to 243 PPM and a under counter 5 stage R/O system down to 7 to 9 PPM.
This system is way better than either of those two. Its the best water quality we can get 0.00 is as low as it goes.
