Delivering a UV dose of 40 mJ\/cm² – the NSF\/ANSI Standard 55 Class A benchmark – this UV 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 3 treats up to 70 litres per minute through RO-treated water, or around 53 litres per minute on standard UK mains supply. That's comfortably enough for a typical 2–4 bedroom home with up to two bathrooms — making it one of the most versatile UV water filter systems in the Armour range for UK domestic properties on borehole or private water supplies.\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 3 shares the same commercial-grade build quality as every model in the 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\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cimg style=\"display: block; margin-left: auto; margin-right: auto;\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0359\/1356\/4293\/files\/uv-guard-logo-retina-400x126.webp?v=1771577593\" width=\"251\" height=\"79\"\u003e\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 3 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 use on a borehole, spring, or private water supply, 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).
