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

Reply from Cyclopure

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.

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.

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.
