Quick and accurate way to test water
I appreciate the quick turn around results and the specified accuracy of the PFAS tests. I am definitely recommending this to others!

I’ve used them twice
I’ve used them twice. Accurate, on time testing. A fraction of the cost of other EPA approved testing methods. Easy to use, customer-centered process. They do a nice job.

A reasonable cost for peace of mind
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.

Thanks very much for your review, and for sharing Cyclopure with your neighbors.

Easy process, great results
Easy instructions, timely results, easy to read PDF report. Most importantly, the whole house filter removed all forever chemicals!
Response from Cyclopure· Jan 24, 2026
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!
