Features a single-stage treatment approach using a selected 4.5 x 10-inch cartridge for arsenic removal. The system includes housing components i.e., sumps, caps, mounting bracket, faucet (lead-free), shut-off device, and tubing for a complete unit. Rated cartridge life is every 12 months or 3,000 gallons whichever comes first (for 50 ppb arsenic).
