The Cyclopure test kit is super easy to use. The analysis time is consistently fast and the response time for questions is also consistently fast. The report is easy to understand.

That's what we aim to do! Thank you!
Process was very straightforward and results were returned in a timely manner. This was exactly what I was looking for in terms of what I needed tested and verified. I was not sure if my water filter was actually removing PFAS after getting a notice from my city about elevated levels, and your test confirmed that it was.

Many thanks!!
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.
