Great inexpensive way to test for PFAS
I liked how easy and inexpensive it was to test my well water for PFAS. Much less expensive than other testing options.

Excellent customer service. I've called a couple times now with questions and both secretaries have been friendly and informative

The kit was easy to follow, came ready to ship back (just drop off at UPS), and got my results within 5 days from when they received the sample. It has put our minds at ease knowing what is (or isn’t) in our water! The whole process does take a bit of time (probably a month or so) from the time you order to when you get your results, but that’s expected and wasn’t a surprise.

Good turnaround on test results.

From the first conversation to the final report...everything thoroughly was laid out and explained. It was easy to collect and return my water sample. I received notification of its arrival to the company followed by a thorough evaluation and report for my system. It was money well spent. I highly recommend this company.

On time with analysis but seems a bit pricey.

Dear Allan thanks for your review. We appreciate your feedback. Cyclopure keeps our water test kit as affordable as possible. We haven't raised the price in five years. All postage, and analytics for 55 PFAS measured to <1ppt. for $79. We've been told it's the lowest price for accurate screening on the market. Let us know if you find another test kit for a lower price! Thanks!
