Delivering a UV dose of 40 mJ\/cm² – the NSF\/ANSI Standard 55 Class A benchmark – this ultraviolet water treatment system provides full-spectrum protection against bacteria, viruses, and chlorine-resistant parasites including Cryptosporidium and Giardia.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eAt peak output, the Armour 4 treats up to 96 litres per minute through RO-treated water or up to 72 litres per minute on standard UK mains supply — making it one of the highest-capacity UV water filter systems available in the UK at this price point.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eManufactured in Australia by UV Guard, a specialist UV water treatment company with over 15 years' experience, the Armour series represents their flagship commercial and industrial range. Every system is built around a WaterMark-certified food-grade 316L stainless steel reactor — the low-carbon variant that offers superior weld corrosion resistance and longevity compared to the standard 304 grade stainless steel used in many competing UV steriliser products.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eWhy 40 mJ\/cm² Matters for UV Water Treatment\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eMany UV water purifier systems on the market are rated at just 30 mJ\/cm² – adequate for basic bacterial disinfection but below the internationally recognised NSF\/ANSI Standard 55 Class A threshold. The Armour 4 is designed to deliver 40 mJ\/cm² across its rated flow range, providing a 4-log reduction (99.99%) in bacteria, viruses, and protozoan cysts. This is the standard recommended for drinking water, process water, warm water recirculation, and medical applications.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eIf you're sourcing a UV water filter for home, borehole, or commercial use, the difference between 30 and 40 mJ\/cm² is the difference between basic bacterial reduction and certified protection against the full spectrum of waterborne pathogens — including Cryptosporidium, which is resistant to chlorine and a common concern on private water supplies across the UK.\u003c\/p\u003e\n\u003ch3 class=\"text-text-100 mt-2 -mb-1 text-base font-bold\"\u003eUV Water Steriliser Flow Rate Capacity\u003c\/h3\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eFlow rates vary depending on your water source and its UV transmittance (UVT). The table below shows the Armour 4's performance at both the standard 30 mJ\/cm² dose and the higher NSF 55 Class A dose of 40 mJ\/cm²:\u003c\/p\u003e\n\u003cdiv class=\"overflow-x-auto w-full px-2
