Twin Multi-Use Water Filter System - Housings Only (GT1-3W)
This Twin Multi-Use Water Filter Housing Set is a versatile and durable filtration platform designed for a range of light-duty applications. Supplied as housings only (no cartridges or fittings), this unit is ideal for users who require flexibility in cartridge selection and system configuration.
With ½" BSP threaded ports and UV-resistant housings, this system is suitable for both indoor and outdoor use and can be installed in multiple scenarios, including:
-
Undersink point-of-use filtration (with compatible mixer tap plumbing)
-
Caravan and RV installations
-
Outdoor kitchens or BBQ areas
-
Small-scale point-of-entry (POE) filtration for applications such as commercial kitchens or granny flats
The dual housing design allows for custom filter setups depending on the water source and treatment needs — for example, sediment followed by carbon filtration, or other combinations tailored to your water quality.
