I purchased the PC600 whole house water filter system about a month ago.  I had plumbers install the system.  The water taste (none), smell (none) is so much better than before.  When I filled up the water bowls for my pets, after a day, there was a film on the bowl when I went to refill.  Now, there is nothing, the bowl looks clean.  So not only the humans in the house noticed the difference in the water, my furry kids noticed as well., as I see them going to the bowl more often now.

I would definitely recommend the system.
