2-Stage Water Filter Housing System – 20” x 4.5” (DOE) with 1” Ports

This pre-assembled 2-stage water filtration system offers a cost-effective and space-saving solution for a variety of domestic and commercial water treatment applications. Built with durable polypropylene housings, the unit accommodates two standard 20” x 4.5” DOE cartridges (sold separately) and is supplied with pressure gauges and a spanner for convenient maintenance.

Perfect as a whole house filter, or used in industrial pre-treatment, this twin-housing system allows staged filtration—for example, sediment prefiltration followed by carbon or specialist treatment, protecting more delicate or expensive filters downstream.
