Ease of testing and fast results

Thanks for the good testing and clear communications

We are pleased with the service you provided to advise that we have contaminated water, along with suggested solutions.
By Jan S.
Straightforward process to obtain the test sample, and easy to ship back. Results received in a reasonable timeframe, with clear explanation.
By Pierre
Was very pleased to know that I only had 2 PFAS and the levels were low. However, bought RO system so hopefully I am good to go. Price was reasonable considering I was able to know if I was consuming poison PFAS and how much.
By Rich B.
You worked with me on a more personal level to meet my particular needs. I appreciate that and thank you for that.
By Kathleen W.
Good updates, stayed within promised timeline.
By Doug H.
I and other Sierra Club members use Cyclopure extensively and know they are always working to get even better to expanding the PFAS compound list and accuracy. They always respond to our questions and requests.
