The core hallmark of ChengrongEra is simple, that is always try our best to keep authenticity.

For any whole house water filtration system, reliable test documentation is essential to prove the safety and hygiene of all materials. And unlike most peers, who skip professional testing or even falsify test reports, our test reports are all issued by SGS, the world’s most authoritative third-party testing institution.

And SGS test results have confirmed that the ultrafiltration membrane filter cartridges independently developed and manufactured by Chengrong Ultrafiltration Factory fully comply with the NSF/ANSI 58-2023 standards, an achievement rarely matched by other manufacturers in the industry.

Then what makes ChengrongEra even more distinctive is that all our ultrafiltration cartridges pass SGS authoritative tests on the first attempt. This fully proves our standardized raw material selection, sophisticated production processes and strict quality control system. All customers can purchase and use ChengrongEra whole house water filtration systems with total peace of mind.

If you are not familiar with ultrafiltration water filters, you may miss that ultrafiltration water filter is the optimal choice for whole house water filtration systems. Thanks to its filtration precision as fine as 0.1μm or 0.01μm, ultrafiltration water filters deliver filtering power 400 times higher than conventional whole house water filters. More importantly, the ultrafiltration water filter also brings no impact on household water pressure.

Therefore, ultrafiltration water filters perfectly meets the two core requirements of a whole-house water purification system: 

1) it can thoroughly intercept impurities such as sediment in tap water and well water.

2) it maintains the original water pressure and flow rate without any reduction.

In fact, SGS reports are not officially recognized by Chinese regulatory authorities, nor is the NSF/ANSI 58-2023 standards a domestic standard in China. The certification required in China is the water approval document.

Since ChengrongEra is a high-end brand focusing on whole house water filtration systems, and the NSF/ANSI 58-2023 standards are far more stringent, we took the initiative to complete this additional standard testing. It is to ensure all customers can use ChengrongEra whole house water filtration systems safely and hygienically.

As one of the TOP 3 manufacturers in the ultrafiltration water filter industry, I, the founder of Chengrong Factory, also aim to benchmark our ultrafiltration membrane quality against global first-tire peers via SGS. This also explains why, despite numerous domestic testing institutions being available, we firmly choose SGS. As SGS boasts global authority, standardized processes and stricter evaluation criteria. Even at a higher cost, ChengrongEra still adheres to professional and impartial third-party testing, after all, ChengrongEra whole house water filtration system solutions are tailored for TOP 2% users worldwide.
