Hope this is the place for this post, just received my CR Spotless water filter today and installed, I was wiped by the Florida sun and humidity but just had to try it. I don't have the best water here but it is city and PH balanced pretty well. I plumbed the CR in a new line that is supplied with soft water, i wanted to extend the life of the resin as long as possible, ( IT AIN"T TOO CHEAP ) at least by my standards. You all know what Florida is like in the summer, we are usually gone to cooler climates but stayed home this year. Washing the car, which I enjoy became a real chore, after my meticulous wash and detail with soft water i had to mico fiber the car with Mcquires final finish to get the water spots off before they became PERMANENT. I really dragged my feet ordering this filter on price alone, but pulled the trigger and am totally impressed. I rushed the job as I was exhausted from the minimal install but the car looks great, I rinsed the car with deionized water to cool it and washed my brush and applied soap directly to the brush. I only intended to do the hood as i mentioned I'm a lazy SOB. but it was so easy i got carried away and washed the car in about 6 or 7 minutes, rinsed with the new water and let dry in the HOT FLORIDA SUN, not a mark left behind. I would really recommend one of these systems if you enjoy washing your car.
