    • 0 ppm, works as expected
Model: RC2-20
First time building a spotless system, these filters worked great, got to 0 ppm within the first minute of running water through them. Just wish SWS sold the centering rings on Amazon too.

    • Terrible system, filters don’t last, brittle center rings constantly deteriorating.
Model: RC2-20
This is my 4th time ordering filter replacements. This company is terrible. I’m done with them. I follow the instructions but these filters don’t last. I ended up going with Culligan, they offer a subscription based product and I’ve consistently been getting 600-700 gallons of use I between filter replacements. Don’t waste your money with these guys. Call Culligan! ... show more

The product was delivered on the day it was promised. CR Spotless does a great job on leaving our vehicles without water spots.

    • Don’t turn water pressure on too much
Model: RC2-20
I have ordered four of these this past year. They seem to last for about six to seven good washes. I have learned that a gallon per minute flow meter, kept at 2.5 gallons per minute along with an RV in line water filter helps a lot and makes it work much better
