Great turnaround.

Easy process to test your water. Quick results.
By Robert Luke B.
After reading great views on their water testing we gave it a try. We ended up doing 3 different tests, some unfiltered and some filtered water from different sources in our home. Test procedure was easy and results came back in a reasonable time. We trust the results, the unfiltered came back with high levels but the filtered came back with less than 1. We recommend them!

Thank you for using our water test kits to make water safer for your community
Results were quick and accurate for my house water decisions.
By DJJ
We moved a year ago from a rural location with well water to a city location with city water and we wanted to test our city water supply for PFAS. We ordered the Cyclopure test kit and followed the simple instructions to test the water out of our kitchen faucet. We mailed in the test sample and received a detailed report in a couple of weeks which prompted us to hook up the fluorocarbon filter our son gave us as a housewarming gift.
