The core hallmark of ChengrongTimes is simple: unyielding authenticity.
Frankly speaking, overstated specifications have run rampant across the whole home water filter system industry. Too many competitors routinely inflate product performance to lure in bargain-hunting customers.
However, ChengrongTimes refuses to follow suit.
Every single technical parameter we publish is 100% genuine.
ChengrongTimes would never exaggerate our ultrafiltration membrane flux or filtration precision—a baseline commitment few in our industry can maintain.
I firmly believe that building a resilient, long-term brand requires absolute honesty with every customer. That is, and will always be, our non-negotiable bottom line.
For any whole house water filtration system, rigorous third-party verification is non-negotiable to guarantee material safety and hygiene. Unlike many competitors who bypass professional testing or even falsify compliance documentation, ChengrongTimes backs every whole home water filter system with official reports issued by SGS and the Shenzhen Academy of Metrology & Quality Inspection (SMQ).
While SGS provides our products with the world’s most authoritative international validation, SMQ—as China’s leading state-authorized laboratory—delivers ironclad diagnostic proof of our material hygiene and structural integrity.
Building on this dual-layered verification, comprehensive SGS laboratory tests confirm that the ultrafiltration membrane filter cartridges—independently R&D and manufactured by the Chengrong factory—fully comply with NSF/ANSI 58-2023 standards. This is a benchmark of regulatory excellence that few in the industry can match.
What truly sets ChengrongTimes apart is our track record: all our ultrafiltration cartridges pass these stringent SGS tests on the very first attempt. This flawless first-pass rate delivers undeniable proof of our standardized material sourcing, sophisticated engineering, and uncompromising quality control.
With ChengrongTimes, global distributors and homeowners can invest in our whole house water filter with absolute peace of mind.
If you are new to ultrafiltration technology, you might not realize that an ultrafiltration (UF) water filter is actually the optimal choice for a whole home water filter system.
With a filtration precision as fine as 0.01μm to 0.1μm, UF membranes deliver a purification power 400 times higher than conventional steel-mesh pre-filters, and 10~50 times finer than standard PP sediment filters.
More importantly, despite this microscopic filtration accuracy, a premium ultrafiltration whole home water filter system maintains an exceptional flow rate with zero pressure drop, ensuring absolutely no impact on your household water pressure.
Consequently, an ultrafiltration whole home water filter system flawlessly satisfies the two ultimate benchmarks of point-of-entry purification:
- 100% Verified Purification: It completely intercepts sediment, particulate matter, and micro-contaminants in tap water and well water alike.
- Maximum Volumetric Flow: It delivers high-volume water output, maintaining your plumbing system’s original pressure and velocity without any reduction.
To be perfectly transparent, SGS documentation isn’t required by local regulatory bodies in China, nor are NSF/ANSI 58-2023 benchmarks part of China’s domestic framework.
The standard legal requirement here is the official State Sanitary Approval for Drinking Water Safety.
As a high-quality global manufacturer of whole home water filter systems, ChengrongTimes refuses to settle for just meeting base-level regional criteria. Recognizing that NSF/ANSI 58-2023 represents a far more demanding regulatory gold standard, we proactively pursued and passed this additional testing. This global compliance isn’t a legal obligation for us—it is a voluntary commitment to ensure absolute material safety and peace of mind for our international clientele.
As the founder of Chengrong Factory—a recognized TOP 3 manufacturer in the ultrafiltration segment—my goal has always been clear: become a brand benchmarked by global peers.
As the founder of Chengrong, a TOP 3 titan in China’s ultrafiltration manufacturing sector, I refuse to let our quality be defined by mediocre standards. We choose SGS—despite its premium cost—because our whole house water filtration system solutions are purposefully tailored for the top 2% global clientele who demand nothing short of perfection.
This relentless drive achieves two fundamental purposes. On one hand, it strips away all marketing noise, proving via undeniable SGS metrics that our proprietary membrane elements stand shoulder-to-shoulder with the absolute best first-tier brands globally. On the other hand, it gives our global distributors and end-users uncompromised peace of mind. When water is utilized for a household’s daily consumption, material hygiene becomes a human responsibility, not just a business metric.
Our top 1% industry standing is never a hollow claim; it is a verified milestone.
- Our Internal Benchmark: We run a unique, vertically integrated full-supply-chain ecosystem in China. Serving as the master ODM/OEM engine behind multiple world-renowned global water filter brands, we have fully mastered the elite playbook of precision manufacturing.
- Our External Verification: Every product bearing the ChengrongTimes name is built to withstand the world’s most hostile laboratory scrutinies.
We set out to bridge the gap between Chinese manufacturing efficiency and global premium quality.
The latest data proves we have succeeded.
