The Dr. Dryden Story

Dr. Howard Dryden

Dr. Howard Dryden
Dryden Aqua Founder

When sea mammals like dolphins, whales, or sea lions are kept in captivity, it is often in chlorinated water. Dr. Dryden worked with these mammals in like conditions for many years. He noticed they often die of lung infections at a young age.

He was able to prove that lung infections in mammals are due to harmful air they are breathing that is just above the surface of the water. This harmful air is called trichloramine, which is the primary cause of chlorine odor that we smell in swimming pools.

Dr. Dryden invented an activated filter media called Activate. Using Activate helped save the lives of dolphins and other mammals by drastically reducing the formation of harmful trichloramines in chlorinated systems.
