316L Stainless Steel
Mineral-Retaining Under Sink Water Filter

Chlorine-removing UF membrane, ChengrongEra proprietary tech, unmatched worldwide<\/p>\n\n\n\n

Unlike Under sink RO Water Filter = Clean but Unhealthy for Drinking
ChengrongEra Under Sinke Water filter = Clean and Healthy for Drinking and Cooking<\/p>\n\n\n\n

1. Chlorine-removing ultrafiltration membr<\/strong>ane, ChengrongEra proprietary technology, no second counterpart worldwide, Ensuring the filtered water is clean and Healthy for drinking and cooking, Unlike RO water filter, whose pure water is clean but unhealthy<\/strong><\/p>\n\n\n\n

Adopting chlorine-removing ultrafiltration membrane, the ChengrongEra proprietary technology. Confirmed by authorized testing institutions in Shenzhen, it could reduce residual chlorine in househole water to an undetectable level, unrivaled globally.<\/p>\n\n\n\n

With a filtration accuracy of 0.01 \u03bcm , the ChengrongEra under-sink water filter blocks 99.99% of bacteria, viruses, residual chlorine, sediment and other particulate impurities, delivering purified water clean for direct drinking. Unlike RO reverse osmosis water filters, it retains natural minerals in water, providing water that is both Clean and Healthy.<\/p>\n\n\n\n

2. <\/strong>Single composite cartridge with 4-stage filtration and a scientifically optimized structure, second to none worldwide. <\/strong>Equipped with ample filter media, ChengrongEra under sink water filter offers high water flow and delivers great-tasting, clean and healthy drinking water.<\/strong><\/p>\n\n\n\n

Folded Cotton \u2192 Activated Carbon Fiber \u2192 PP Cotton \u2192 0.01\u03bcm Chlorine-Removing Ultrafiltration Membrane, 4 types of filter media are scientifically compounded in one single cartridge, compact in size yet filled with ample internal filter media, apart from most peers that skimp on filter materials.  <\/p>\n\n\n\n

0.01 \u03bcm chlorine-removing ultrafiltration membrane serves as the final filtration stage. It not only traps bacteria, viruses and residual chlorine from raw water, but also effectively intercepts contaminants generated from the front activated carbon fiber layer, rational structural design providing double protection for clean and healthy drinking water.<\/p>\n\n\n\n

3.<\/strong> ChengrongEra under-sink water filter is tested by SGS and complies with NSF\/ANSI 58-2023 standards<\/strong>. Meanwhile, certified by the Shenzhen Academy of Metrology & Quality Inspection (SMQ), the mineral-like water ChengrongEra under sink water filter<\/strong> produces fully meets direct drinking standards<\/strong>. Such superior performance is rarely rivaled in the industry.  <\/p>\n\n\n\n

4. 316L stainless steel outer housing, not only premium in the matrials but also much thicker.
