Land & Water Replacement 10" x 4.5" Blue Filter Housing & Mounting Bracket

The Land & Water 20" Big Blue Filter Housing Kit is a heavy-duty replacement solution designed for large homes, commercial sites, and light industrial applications where high water volumes and flow rates are required. Its robust build and larger 20" x 4.5" capacity make it ideal for handling higher sediment loads and extending cartridge life compared to standard housings.

Installed on mains plumbing, this housing accommodates a wide range of 20" Big Blue filter cartridges (sediment, carbon block, or specialty media), providing reliable removal of chlorine, taste, odour, and particulate matter. With flow rates of up to 75 litres per minute, it ensures clean, clear water across all taps, showers, and appliances — while safeguarding hot water systems and household fittings from premature wear.

This system is tested and certified to meet the WaterMark specification AS/NZS 3497:1998 Amdt 1 2001 Drinking Water Treatment Units—Plumbing Requirements, Certificate Number 23124, guaranteeing compliance with Australian standards.
