I had been concerned that I had not received my PFAS Test Results. Immediately after I raised the issue, the Cyclopure team swung into action with a personal email, attached the test results and provided an audit from their IT department showing when the results had previously been sent. This is a team that takes great pride in their product and image. Well done.

Response from Cyclopure· May 29, 2024
Hi Gary, We sent your report out on May 24 from the email address [email protected]. We saw your erroneous review last night so we forwarded the report again. Please call us at 312-639-5009 if you haven't received it. Our IT Team shows it has being delivered. Actually 5/24 was before the ten BUSINESS day window in which we promise our results! Let us know if we can help.
Customer service was excellent. When the test didn't work, they contacted me and sent back a new test kit, twice.

Cyclopure test kit arrived quickly after order and return sample was processed equally as fast. Thorough test results for PFOA's provided. Very happy.

I was so pleased with the information I received from Cyclopure, Inc. Unfortunately, City of Calhoun Ga water is FULL of PFAS and other poisoned chemicals. We were advised that 1 area was now fixed. I tested with Cyclopure and we are STILL contaminated.
