Gravity-fed water filters offer an excellent solution for Australian households seeking chemical-free water purification without electricity or plumbing modifications. Today we’re comparing two popular systems: the American-made Big Berkey and British ceramic specialist Doulton’s gravity filters. Both promise superior filtration, but they take distinctly different approaches to delivering clean drinking water for your family.
What is the Big Berkey?
The Big Berkey is a stainless steel gravity filter system featuring Black Berkey purification elements. This American-designed system uses a proprietary blend of carbon and other media to remove bacteria, viruses, heavy metals, and chemicals. The sleek stainless steel construction holds 8.5 litres and can accommodate 2-4 filter elements. It’s positioned as a premium “purification” system rather than just filtration, claiming to handle even untreated water sources.
What is a Doulton Gravity Filter?
Doulton gravity filters combine traditional British ceramic filtration technology with modern stainless steel housing. Their ceramic cartridges, made from diatomaceous earth and silver, provide natural antimicrobial properties. Available in various sizes (7L to 12L), Doulton systems focus on removing sediment, bacteria, chlorine, and improving taste. The company has over 180 years of ceramic filtration experience, making them a trusted name in Commonwealth countries including Australia.
Key Differences
Performance Comparison
Big Berkey elements claim broader contaminant removal, including viruses, heavy metals, and pharmaceutical residues. Independent testing shows excellent performance against bacteria and chemicals. However, Berkey systems aren’t certified by Australian standards bodies.
Doulton filters excel at bacterial removal and chlorine reduction, with many cartridges certified to Australian/New Zealand standards (AS/NZS 4348). Their ceramic construction provides reliable pathogen removal, though virus filtration capabilities vary by cartridge model. Doulton’s performance is well-documented and independently verified.
Cost Comparison (AUD)
Big Berkey systems cost $550-650 through Australian retailers, with replacement Black Berkey elements around $180-200 each. While expensive upfront, the long filter life (11,000L per element) reduces ongoing costs.
Doulton gravity systems range from $300-500 depending on size and configuration. Replacement ceramic cartridges cost $80-120 each but require changing every 2,000-3,000L. Over time, Doulton’s running costs are higher due to more frequent replacements.
Ease of Use/Installation
Both systems require no plumbing or electricity. Big Berkey setup involves installing elements into the upper chamber – a process some users find tricky initially. The stainless steel spigot feels robust and the system looks professional on countertops.
Doulton systems typically feature simpler cartridge installation with threaded connections. The ceramic elements are fragile and require gentle handling, but replacement is straightforward. Some models include helpful accessories like storage stands.
Long-term Running Costs
Over five years, assuming a family of four uses 8L daily, Big Berkey costs approximately $750-850 total (system plus replacement elements). Doulton systems cost around $800-1,200 over the same period due to more frequent filter changes, despite lower initial investment.
Which is Better For…
Budget-Conscious Families
Doulton offers lower entry costs and performs excellently for typical Australian tap water improvement. The ceramic technology reliably removes chlorine and bacteria without the premium price. Available through Clean & Native’s Australian store with local warranty support.
Off-Grid or Rural Properties
Big Berkey’s robust purification capabilities suit questionable water sources better. The longer filter life reduces maintenance frequency – important for remote locations. However, ensure you can source replacement elements reliably in Australia.
Health-Conscious Urban Users
Both systems excel here, but Big Berkey’s broader contaminant removal appeals to users concerned about pharmaceutical residues and industrial chemicals. Doulton’s certified performance provides peace of mind for families prioritizing verified filtration standards.
Renters and Frequent Movers
Doulton’s lighter weight and simpler design make it more portable. The ceramic cartridges, while fragile, are easier to pack safely than Berkey’s proprietary elements.
Our Verdict
Both systems deliver excellent filtered water, but serve different needs. Choose Big Berkey if you prioritize maximum contaminant removal, don’t mind the higher upfront cost, and want longer filter life. The system excels for challenging water conditions and health-conscious users seeking comprehensive purification.
Select Doulton if you prefer certified performance, lower initial investment, and proven ceramic technology. It’s ideal for improving typical Australian tap water and offers better value for basic filtration needs.
For most Australian households, Doulton provides the better balance of performance, cost, and local support. However, Big Berkey wins for serious water purification requirements.

FAQ
Are Big Berkey filters legal in Australia?
Yes, Big Berkey systems are legal to sell and use in Australia. However, they cannot make therapeutic claims and aren’t certified to Australian standards. They’re sold as water filters rather than purifiers under Australian regulations.
How often should I clean my gravity filter?
Clean the chambers monthly with warm soapy water. Doulton ceramic cartridges can be scrubbed gently with a soft brush to maintain flow rate. Big Berkey elements should only be cleaned according to manufacturer instructions to avoid damage.
Which system has better customer support in Australia?
Doulton has established Australian distributors and local warranty support. Big Berkey support primarily operates from the US, though some Australian retailers provide local assistance. Consider this when choosing between systems.
