The test was easy to perform, the directions were very clear, the response time was very reasonable, and the price was on point. We received our results in a very timely fashion. Consumer Reports recommended this company so I feel good about using their service.

Super convenient to order. Very easy to take a sample and send back. Only a fraction of the cost of other labs in our area.

The method used by Cyclopure is easy to learn and emailed results allow me to keep an accurate record for the effectiveness of my water filtration system.
