got my results in five days not 10 to 14. price was fair
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!
Just looks for plastics
I wanted to have my water tested not just for plastic but for other containments. Sadly this didn't offer that.
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.
Did what was expected nothing more
Did what was expected nothing more. I wish the report I received had more explanation of the issues and risks. What can be done to fix the issues- great opportunity to have sold one of there filters and why there filter is better. Also maybe a discount on the filter to trigger a buy. I think they did ok but without further data I am unsure- like we used this method to test this and it’s certified by X and error rate is between X and Y. Just sending out a report to a homeowner is such a wasted opportunity

We completed a water filtration project with Cyclopure. They were easy to work with; their product works great and is easy to implement; their support staff was knowledgeable and helpful. The packaging and shipping were done quickly and securely. I am happy with the product and endorse it for PFAS filtration.
A satisfied customer
I have been using Cyclopure PFAS test kits for the past year and a half to monitor PFAS pollution in my well and several other wells in my neighborhood. The kits are easy to use and sending the kits back to Cyclopure is a snap. The test results are returned promptly. I have also installed the whole home filter and have had PFAS free drinking water for a year now. Cyclopure is a great company with very good people that are always ready to help.

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

Easy instructions, timely results, easy to read PDF report. Most importantly, the whole house filter removed all forever chemicals!
