The test results were as I was told would be the same as if the EPA came into my home and sampled my well water. Professional results. What more can I ask for. I hope others will see my FB post and request test kits from you.

Ease of use with product and quick communication with employees to get additional information after receiving results.

Good results. Significantly less expensive than other labs.

Kit was easy to use and the whole process including mailing and result turn around time was very efficient!

I had you do a test of my water for me but what I got back for results was numbers with no context. I don’t know what to think about the test results. There was no report of any kind just numbers that meant almost nothing to me. How do I interpret these.

Hi Ed, sorry you found the report values confusing. They are presented in standard format. To your question, "how do I interpret these" - your report included a qualitative statement noting that "All 55 PFAS tested measured non-detect." As you hopefully saw, each report includes details on State and EPA PFAS regulations to provide context for PFAS detections. The State and Federal details also include links for further information at State and EPA websites. In your particular case, zero detection means no PFAS, which as we noted in your report is "Good news."
Outstanding customer service. Timely shipping and results. This is a very simple test that matches the results I got from a much more expensive lab (that test was done by the county). I will be purchasing more tests in the future for periodic tests. At this price, I can afford to do that.

We knew that the town had a PFAS problem in the municipal water supply and we wanted to make sure that the filter in our refrigerator was removing PFAS from our drinking water. Cyclopure had the only reasonably priced test kit for home use at $79. I had researched a bit online and found several municipalities and non-profits that had successfully used the Cylcopure test. The process was quick and efficient, and fortunately the Samsun refrigerator filter does seem to do the job for us.

I discovered that the water purification system that I have owned for over 30 years is working the way it is supposed to.
