Quick, reliable (as tested by Consumer Reports), reasonably priced, and very clear and comprehensive communications.

The test was simple with easy to follow directions. Results were timely and within the alloted time we were told to expect. Our test results are helpful and concise in correcting the water we have.

I purchased a PFAS detection kit from Cyclopure. It was intuitive and easy to use. Also easy to send back to Cyclopure for analysis. Everything was streamlined and results were easy to understand. Highly recommended!
