Perfect for outdoor activities and a must in hostile environments where electricity, water pressure or treated water may not be available. The Crown Berkey system removes pathogenic bacteria, cysts and parasites entirely and extracts harmful chemicals such as herbicides, pesticides, VOCs, organic solvents, radon 222 and trihalomethanes. It also reduces nitrates, nitrites and unhealthy minerals such as lead and mercury.
