Why Choose the 20 inch by 4.5 inch Twin Big Blue Rainwater Tank Water Filters?

This twin 20 inch by 4.5 inch Big Blue Whole Home Filter System is designed for high-volume chemical water filtration, making it ideal for treating rainwater tank water throughout the entire house. The system includes a spun sediment filter and a silver-infused anti-bacteria carbon block filter, a mounting bracket, and a housing opening ring spanner, offering a complete initial setup with a high-flow capacity.

Compact Design and Powerful Performance

This twin-cartridge system is built to accommodate all standard 20 inch by 4.5 inch cartridges, ensuring a high flow rate and long filter life, typically lasting 6 to 12 months or approximately 150,000 litres, depending on the turbidity of your tank water. The system features 1 inch BSP inlet and outlet ports, and the housings include a pressure release valve button for easier cartridge changes. The two-stage filtration consists of a First Filter, which is a poly spun sediment filter that removes particles like dust, dirt, clay, leaves, debris, and suspended solids, and a Second Filter, which is a silver-infused anti-bacteria coconut shell activated carbon block filter. This carbon block is essential for reducing or removing chlorine, odour, some colouration, taste, pesticides, herbicides, volatile organic compounds, and a wide range of impurities. It is important to note that while the silver infusion provides anti-bacterial properties, only a $0.5\text{micron}$ carbon block will remove cysts and micro-organisms like giardia, cryptosporidium, and blastocysts. The actual measurements for the spun sediment and carbon block filters are approximately $\pm 51\text{cm}\times \pm 12\text{cm}$ and $\pm 50\text{cm}\times \pm 12\text{cm}$, respectively. All water contact parts are manufactured from high-quality, BPA free food grade plastics.

Seamless Integration and Safety Note

The filter housings are available in both Watermark certified or NON-certified options. The vendor strongly advises that Watermark certification is required, along with a Pressure Reducing Valve (PRV) and Non-Return Valve, when connecting the system directly to a constant-pressure mains water supply, as specified by Australian Standards. For other filtration purposes, such as tank water not under constant mains pressure, certification is not mandatory. The system carries a full 12-month warranty on all parts and a 30-day money back guarantee. Furthermore, the description reminds all customers that any water filter system under constant pressure is required by regulatory standards to be fitted with an AS3497 approved pressure reducing valve and back-flow prevention device
