I had some concerns about whether local golf courses were running off into our drinking water. The Cyclopure test was a reasonable cost, and gave me real peace of mind. I shared the results with my neighbors too, and they were happy to hear about the test.

Easy instructions, timely results, easy to read PDF report. Most importantly, the whole house filter removed all forever chemicals!

Thank you for being a Cyclopure customer! We're glad the Purefast Home filter you installed is doing the job of removing PFAS down to non-detect!

This is my 3rd water test kit and I have been satisfied with each process. I have recommended your product to a few friends that are concerned with "Forever" chemicals in their water supply.
