Dr. Dryden's Active & Enhance Advanced Filter Media

Dr. Dryden's Activate Glass Filter Media

Dr. Howard Dryden is the inventor and founder of Dryden Aqua. For many years, he worked with ocean mammals such as whales, dolphins, and sea lions and noticed they often died at early ages of severe lung infections. Through his research, he proved the animals were breathing trichloramines in the air caused by chlorine use. 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.
