From start to finish they exceeded my expectations. My hard earned money was well spent on my new Kinetico system, making our water safer for my family. I am stunned by their attention to detail and fantastic customer service. I would give more stars if I could!

Water treatment may seem like a small piece of the puzzle, but it’s actually critically important to our work. I wouldn’t choose any company other than Secondwind.
Bonnie Lewis, Lake Sunapee Protection Association
THANK YOU!!! for everything. You and Shane were both very professional and excellent at explaining and answering questions. I am really impressed with how simple and self explanatory the system is. The warranty and your customer service are added reassurance. I wish I had found you years ago.

Frequently Asked Question

How do I know if I have PFOA/PFOS in my water?

Like most of the health related contaminants we deal with, there is no taste or odor or color associated with PFOA, present in the parts per trillion levels that are believed to represent a health risk.  So the only way to know is to test.

Have you had success in treating for PFOA/PFOS? 

Yes. We reviewed all the available data, conferred with colleagues in other affected areas, and completed pilot testing on current installations in homes affected by PFOA infiltration. In addition, we had a year-and-a-half history of successful treatment of PFOS in the Pease area to draw on. Both our drinking water systems and whole-house treatment systems have come back with non-detectable PFOA and other related contaminants.
