Germicidal Disinfection Sterilizer UV Systems are effective methods for providing safe, bacteria free water for your residential or office needs.

GDS systems eliminate taste and odor from drinking water. They remove microbiological contaminants without the use of expensive chemicals that require maintenance, and they destroy bacteria, viruses, and other organisms, storing them safely inside a factory-sealed stainless steel chamber. They’re American-made, too.
