I got this survey but no test results.

Professional, Reasonable, Service-oriented, Reliable and Easy! I'm a veterinarian and know how vital it is to have reliable test results. Cyclopure PFOS test kits provide accurate results, kits are exceptionally straightforward to obtain, to use, to return and the results are astonishingly prompt.The results compare favorably to much more expensive tests but are so much more convenient to obtain. Any questions or follow up are answered by a person. Impeccable service. I genuinely appreciate that the USPS is the transport system, with tracking included in the price.

Since several wells in my area are contaminated with PFAS, I was nervous. Cyclopure made testing, sending and getting results easy. The results were clear and easy to understand. Communication was thoughtful and thorough. Great company!

Seemed a well-made product that solved the problem of PFA in the local city water supply. Test kits were processed quickly, a question about report results were addressed, and the filter arrived on-time (with a return envelope for the old filter to keep PFA out of the environment.
