The HALO Defender II is a single filter cartridge, whole home solution that reduces PFOS/PFOA, lead, cysts, chlorine and chloramine. Inside the system, water passes through a specially formulated activated carbon block filter cartridge where the reduction of these contaminants is achieved. As this filtered water leaves the outlet of the system, a flow meter communicates the treated water volume to the HALO Smart Monitor which notifies the user when filter replacement is necessary via a multi color LED visual alert display. The system is certified to NSF/ANSI 53 for whole home applications for the reduction of lead, PFOS/PFOA, and cysts. The HALO Defender II has a certified capacity of 93,250 gallons between filter changes and a certified peak flow rate of 4.21 GPM. For higher flow rate applications, multiple units can be installed in parallel. 

Lead can enter our drinking water through corrosion of plumbing systems and lead service lines. Lead is a known to pose health risks to people of all ages including unborn fetuses. PFOS and PFOA are man-made chemicals that are appearing in our drinking water across the county and are suspected to cause a variety of health issues.
