Impressive, inexpensive PFAS breakdown
I found this to be an easy and inexpensive way to get the main data on the various PFAS contaminants in my well water. Pleased with simple instructions, process, time frame and excellent communication by Cyclopure staff. This was for my own peace of mind as I had no obligation to prove levels to anyone. Please check to see if you need a certain lab, certification or format before your PFAS test.
