As a top three player in the stainless steel pipeline ultrafiltration industry, Chengrong Ultrafiltration Factory has a unique advantage that, we are a full supply chain manufacturer with zero quality complaints for six consecutive years. Every client who has tried Chengrong's ultrafiltration (UF) water filtration system highly recognizes our uncompromising quality.
Over the past 18 years, our ultrafiltration water filters have been validated by countless B2B brand partners. With superior quality that is "more reliable than insurance", we have achieved nearly 90% customer repeat orders. Partnering with Chengrong ultrafiltration factory means peace of mind for your business, and at least 10% higher profits in the market.
ChengrongEra is our factory own brand, launched in mid-2025.
Our signature product, the hand-washable filter element whole-house water filter for the main water inlet pipe, features an ultra-high filtration precision of 0.1 microns (400 times higher than traditional pre-filters) while maintaining full water pressure at household faucets. Specifically engineered for turbid well water, and even yellow muddy stream water, it delivers unparalleled purification performance.
The filter element made by PVDF ultrafiltration membrane, is independently R&D and manufactured by Chengrong UF factory. Sourced from top-tier domestic and international material suppliers, it represents a premium configuration rarely found in domestic competitors, with three key components imported, as no domestic alternatives, giving our PVDF membrane an inherent quality edge from the raw material stage.
Unlike our peers who reduce costs by spinning an ultra-thin PVDF layer (sacrificing durability for "affordability"), Chengrong factory adheres to strict quality standards with 30% more material usage than industry averages. Our proprietary single-hole spinneret die design ensures uniform membrane fiber wall thickness and dense, uniform micropores, resulting in a 40% higher water flux than peers under the same operating conditions.
Second, our finished UF membranes undergo purification with purified water and disinfection with specially formulated alcohol, while most competitors use chemical treatments. Although chemical processing is more convenient, it leaves harmful residues. At Chengrong, we adopt a critical stance toward chemical agents and avoid them whenever possible, because safety and quality always take precedence over efficiency. Alcohol disinfection, though more technically demanding, ensures complete volatility with zero residual risks.
I have always believed that diligence outweighs talent. As a grassroots entrepreneur with no background or resources, I've made it our mission to take on challenges that others shy away from. By a happy accident, this commitment has led Chengrong factoy to develop unique insights into ultrafiltration technology through continuous experimentation and practice, insights that remain unparalleled in the industry.
Third, why do many customers use our hand-washable filter elements for 5, even 7 years?
The answer lies in our proprietary dual spiral mixing and constant temperature bonding technology with A and B adhesives, a process unmatched in the industry. Additionally, we implement 100% full-process quality inspection (no random sampling) to ensure every ultrafiltration membrane meets our rigorous standards. This level of quality control is virtually unheard of in the stainless steel pipeline ultrafiltration sector.
Rural areas often rely on well water, which are prone to turbidity and high levels of fine suspended sediment, especially during rainy or typhoon seasons, when well water, stream water, and spring water are easy to turn into turbid yellow muddy water.
Traditional pre-filters on the market have a maximum precision of 40 microns, unable to remove fine sediment, colloids, and other impurities. In contrast, ChengrongEra whole house water filter with 0.1-micron filtration precision, completely intercepts sediment, rust, colloids, and insect eggs, making it the ultimate whole-house water purification solution for rural turbid water.
If you live in a rural area and want permanently clear drinking water, try ChengrongEra whole house ultrafiltration water purifier. Our unique design uses purified water for backwashing, ensuring not only surface impurities but also clogging particles deep within the micropores are thoroughly removed. No other brand in the industry offers this technology.
Our 5-year filter element warranty is no empty promise – it's a proven fact backed by thousands of satisfied customers.
