Clean, safe water is essential for every Australian home—whether you live in a metropolitan area, a regional town, or rely on bore/well water in remote locations. With rising sediment levels, ageing pipes, and varying water quality across states, more households are turning to point-of-entry (POE) filtration systems that deliver consistent, contaminant-free water straight into the home.
Among these solutions, Big Blue Filters in Australia have rapidly grown in popularity due to their high flow rate, durability, and ability to handle whole-house applications without compromising pressure. CoPure’s Big Blue series is engineered to meet Australian conditions, supporting everything from urban municipal supplies to high-sediment bore water.
Big Blue Filters are large-capacity water filtration systems designed for high-flow residential, commercial, and light industrial applications. They typically use a two-stage or three-stage filtration setup, where water passes through successively finer micron ratings.
A standard setup usually includes:
Because of their wider 4.5-inch diameter housing, Big Blue Filters offer longer filter life, higher contaminant-holding capacity, and better performance under heavy water usage.

Australian homes often face water challenges that require a robust POE filtration system:
Big Blue Filters addresses these issues efficiently, making it a preferred choice for Australian homeowners seeking reliability and long-term performance.
CoPure’s Big Blue Filters in Australia combine heavy-duty construction, NSF-certified materials, and a user-friendly design, ensuring both performance and longevity. They are particularly effective in homes with multiple bathrooms, large appliances, or high daily water demand.
This ensures uninterrupted water pressure even when multiple taps, showers, washing machines, or dishwashers run simultaneously. For large homes, this is a critical advantage.
Built from impact-resistant materials with a reinforced design, CoPure Big Blue housings withstand:
A pressure relief valve makes cartridge changes simple and safe.
All wetted surfaces meet strict NSF standards for safety and materials performance—important for whole-house systems where all water used for drinking, cooking, and bathing passes through the unit.
Designed for straightforward installation at the point of entry. Filter changes require only a spanner wrench, with no backwashing or regeneration cycles needed.
Because of their large capacity, Big Blue cartridges last significantly longer than standard-size filters, reducing annual maintenance costs.
This stage removes:
Using a 5-micron filter ensures protection for both the water system and downstream carbon cartridges.
This high-performance activated carbon block:
Carbon block filters are significantly more efficient than granular carbon due to their increased surface area and longer contact time.
Removes sediment, chlorine, organic chemicals, and bad taste/odour—making water safer for both consumption and daily use.
Filtered water extends the lifespan of:
By preventing sediment buildup, you reduce repair and replacement costs.
Big Blue Filters maintain consistent water pressure even at high usage points, unlike smaller filters that often restrict flow.
Knowing your water is free from harmful or unpleasant contaminants is especially important for families, children, and rural households.
CoPure Big Blue Filters are particularly suited for:
Given Australia’s diverse water environments—from Queensland rainwater tanks to Victorian municipal supply and WA hard water—these filters provide a reliable universal solution.
CoPure is committed to delivering reliable, high-flow, and high-performance filtration systems designed specifically for the diverse water conditions across Australia. Whether you need cleaner drinking water, better shower quality, protection for appliances, or sediment removal from bore water, CoPure’s Big Blue Filters offer a robust and cost-effective whole-house solution.
As water quality concerns continue to rise, investing in a durable and efficient point-of-entry filtration system is no longer optional—it’s essential. Big Blue Filters in Australia from CoPure offer a proven way to deliver clean, clear, and safe water to every tap in your home while maintaining excellent water pressure and reducing long-term maintenance costs.
