Cyclopures test was accurate
Cyclopures test was very close to the mpca (Minneapolis pollution control agency) test, way less expensive and way faster results!

Cyclopure made getting our well water tested for PFAS chemicals easy with clear easy to follow instructions for collecting and mailing our water sample. We were impressed & appreciated the very detailed report & the information that clearly explained the findings for our water test.

You were fast, helpful, and now I have data I can work with. We started better filtration right away. I'm recommending you to my neighbors. Thank you.

Thank you! Together we can eradicate PFAS from drinking water one drop at a time!
Lab and results time could be improved. But other wise great!

Hey there - We thank you for using our water test kits to sample water for PFAS! Just looked back at your records and there hasn't been one sample/result published outside of the 10-14 BUSINESS day window we promise for turnaround of results.
You did what I contracted you to do on a timely manner and provided a complete report regarding the water sample I sent you. And my water sample did not have any PFAS detected by your testing procedure.
