Great communication and what seems to be a great product.
By Paul C.
I appreciate the quick turn around results and the specified accuracy of the PFAS tests. I am definitely recommending this to others!
By Vicki
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.

Easy peasy process. Quick with the results. Would recommend!

They make it easy to know if PFAS are in your water.

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 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!
