Culligan HF-150A Whole House Sediment Filter Housing — 3/4 inch Inlet/Outlet, UV-Resistant, 5-Year Warranty

The Culligan HF-150A Whole House Sediment Water Filter Housing protects your home by filtering out dirt, sand, and silt before it travels through your pipes. Attach it to your cold water line to help keep faucets, showers, laundry, and appliances delivering clearer water. A unique self-cleaning O-ring helps prevent leaks and clogging, while an integrated pressure relief valve makes cartridge changes smoother. The opaque housing shields cartridges from light, and the unit is compatible with most Culligan cartridges sold separately.

Designed for standard 3/4 inch inlet/outlet connections on the main cold-water line, this housing offers straightforward installation and reliable protection for your entire home. The pressure relief valve reduces downtime during maintenance, while the self-cleaning O-ring minimizes the risk of leaks and obstruction. The HF-150A is NSF International certified for structural integrity and backed by a five-year limited warranty, underscoring durability and long-term value.
