It went fine, takes a bit to get results - interestingly our results came back no detections and our neighbors came back high - so state is coming back to test our house for free. We must have the best house filter :).

Cyclopure gives great customer service and instructions to help provide clean water to my whole house. We had issues with our install but cyclopure was fast to assist and we found the mistake in our setup. Will continue to use cyclopure and have recommended this product to our neighbors.

I called cyclopure because the box the kit came in was wet from sitting out over night . The Cyclopure representative I spoke to was very helpful in getting me another kit
