Thank you!!
The representative at Cyclopure were very helpful and explained several facts about PFAS that I did not know. The water collection was extremely easy and the results were posted promptly. I also found the website with videos very informative and I would recommend this company if you need your water tested for PFAS.

Many thanks!
We had a new well drilled and are in an area going through issues with PFAS contamination so felt it necessary to have the water tested for such contaminants. We chose Cyclopure, Inc. because of its affordability and the recommendation of the local township. We received the kit promptly. It was easy to use and send back. Very happy with the quick and thorough results sent by email in PDF format. Thank you so much that we can be reassured our water is safe.

So glad we could be of help!
I love this company! I purchased the Purest filter for my Brita Water Pitcher (and will continue to buy them) and I finally feel safe drinking the water. We use the water for cooking, coffee, drinking and our dog! So it's important to not be consuming PFAS in the water we consume. Besides, the customer service is AMAZING. They reply back to you and I even received a phone call. HIGHLY recommend this company and their products. AAA+++
