Great communication and what seems to be a great product.

I appreciate the quick turn around results and the specified accuracy of the PFAS tests. I am definitely recommending this to others!

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. 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. 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

Thanks for the feedback. It's tough because we're a materials chemistry lab that has developed DEXSORB® a highly selective adsorbent that removes PFAS from water. We're not big on salesmanship or telling folks how to think. Our tests are designed to be screening tools. Hopefully homeowners know that Cyclopure is a resource and If PFAS is present in a report we are one phonecall away from discussing remediation methods. Discounts are always available to students, seniors, veterans and communities. Again, we appreciate your opinion and will take a look at our marketing efforts.

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