20" Clear Big Blue Filter Housing – Transparent Design with Copper Threaded Ports

The 20" Clear Big Blue Filter Housing offers high-capacity water filtration with a transparent bowl that allows you to see the condition of the filter cartridge without opening the housing. 

This clear design is ideal for homeowners and businesses that want visual confirmation of when a cartridge needs replacement. Ideal for sediment-heavy or iron-rich water, this housing provides powerful first-stage filtration for whole house systems using municipal or well water.

Built for durability and performance, the filter head features copper-threaded 1" NPT inlet and outlet ports that provide secure, leak-free connections and resist cross-threading or cracking. A built-in pressure relief button on the cap allows for easy air release when changing filters.
