Explore Our Range of Water Filter Housings

We offer different housing configurations to suit various installation requirements, operating conditions and filtration capacities.

10-Inch Water Filter Housings

10-inch filter housings are widely used in domestic and light commercial water filtration systems. Compatible with standard 2.5-inch diameter filter cartridges, they provide a practical solution for sediment filtration, activated carbon filtration and specialist water treatment applications.

20-Inch Water Filter Housings

20-inch filter housings offer greater cartridge capacity and filtration surface area compared with standard 10-inch models. They are suitable for applications requiring higher flow rates, increased dirt-holding capacity or longer cartridge service intervals, depending on the filtration media used.

Big Blue Water Filter Housings

Big Blue filter housings are designed for larger 4.5-inch diameter cartridges and are commonly used in whole-house, commercial and industrial water treatment systems. Their larger capacity makes them suitable for applications requiring higher water flow and greater filtration capacity.

Stainless Steel Filter Housings

Stainless steel filter housings provide a robust solution for demanding water filtration environments. Available in different configurations, they are suitable for commercial and industrial applications where durability, operating conditions and material compatibility are important considerations.

Multi-Stage Filter Housing Systems

Multi-stage filter housing assemblies combine two or more housings to accommodate different filtration cartridges in sequence. These systems allow multiple treatment stages, such as sediment removal followed by activated carbon filtration, within a single installation.

Filter Housing Accessories and Replacement Parts

Maintain your filtration equipment with our selection of compatible housing accessories and replacement components, including mounting brackets, O-rings, housing spanners, pressure gauges, pressure relief valves and cartridge centralising rings.

How to Choose the Right Water Filter Housing

Selecting the correct filter housing is essential for achieving reliable filtration performance and maintaining system compatibility.

Before choosing a housing, consider the following factors:

  • Cartridge dimensions: Check the required cartridge length and diameter, such as 10-inch, 20-inch or Big Blue.

  • Connection size: Select compatible inlet and outlet connections, including ½-inch, ¾-inch, 1-inch or larger BSP/NPT ports.

  • Operating pressure: Ensure the housing is rated for the maximum working pressure of your water supply.

  • Flow rate: Choose a housing that accommodates the required water flow without unnecessarily restricting system performance.

  • Operating temperature: Check that the housing materials are suitable for the application temperature.

  • Material compatibility: Consider the housing construction materials and their suitability for the water being treated.

Always check the manufacturer's specifications to ensure the selected housing is appropriate for your installation.
