Today, I came across actor Jiang Wu’s interpretation of "doing business", it perfectly aligns with the brand vision of ChengrongEra and the original aspiration that drove me to found the company.
Sharing it in this article is also a form of self-encouragement.
"‘Sheng’ (生) signifies vitality and creation; ‘Yi’ (意) stands for sincerity and kindness. Doing business（做生意）is about making life better for the seller and the buyer both. Beyond transactions lies an aspiration that transcends pure profit, it is the flow of trust between people, and even more, an endless vision for a better life."
Many people instinctively think of making money when they hear "doing business," but I believe the prerequisite for profitability is that products must deliver tangible value to customers. Customers’ lives should be enhanced with better experiences through purchasing our products.
Otherwise, making business jsut mean to lose money.
Even if profits are made now, losses will inevitably come in the future.
ChengrongEra Ultra-filtration Water Purifier: Uniquely Different from the Market
Every water purifier under ChengrongEra brand stands out from similar offerings on the market.
My courage to invest heavily in R&D stems from two key factors:
18 years of hands-on experience in the water purification industry, which has given me a profound understanding of water; and integrating my personal life experiences with real use pain points shared by our users. These ensure all ChengrongEra water purifier devices not only help end-users improve water quality, but also are easy to operate, use, and maintain.
Innovation and upgrades in product functionality, structure, and manufacturing are never empty talk, those in the manufacturing industry cannot afford empty promises. To progress, we must invest substantial resources, endure countless days and nights, and polish and optimize our products thousands of times.
It is through this dedication that ChengrongEra and its several classic water purifier devices exist today.
Manual Cleaning Pre-Filter: Solving Rapid Clogging
Our manual cleaning pre-filter addresses the common problem of rapid filter clogging.
There are three main reasons why external pressure membranes clog quickly—and we’ve resolved them all:
Superior membrane quality. Our external pressure membranes come with a backing layer. Some competitors reduce costs by spinning the functional PVDF membrane (the core filtration layer) extremely thin, but the ultrafiltration membranes from Chengrong factory always use full, high-quality materials. Cutting corners is an absolute red line we never cross. By the way , I have to mention it that we only use high-grade imported raw materials that are hard to find elsewhere in the industry.
Mismatched membrane flux. Clogging occurs when household water usage exceeds the membrane’s capacity. Based on years of practical experience, I’ve developed two formulas that balance water usage experience and economic costs, helping customers select the right membrane flux for their household needs. I have the confience that. no one in the industry boasts greater professionalism than we do.
Incorrect maintenance. For external pressure membranes, thorough cleaning and extended lifespan can only be achieved through simultaneous manual cleaning and backwashing. This method removes both surface impurities and contaminants trapped in the 0.1-micron pores, significantly prolonging the membrane’s service life.
ChengrongEra pre-filter for whole house water purification features an innovative dual-clamp design (upgraded from a single clamp). Users only need to remove the lower cylinder to perform simultaneous manual cleaning and backwashing, simple and effective.
Intelligent Self-Cleaning Pre-filter Models: For Hands-Free Convenience
Some users prefer not to clean filters manually, so we developed the intelligent self-cleaning Pre-filter for whole house water purification,
Their key difference lies in filtration accuracy: 0.1 microns and 0.01 microns respectively.
Users simply set the filter cleaning interval and duration in advance, and the system operates automatically.
While these models are slightly more expensive, the time and energy saved create greater value for users, especially recommended for households with elderly people or children who may find manual cleaning inconvenient.
Mineral-Water-Like Kitchen Water Purifier: Retaining Essential Nutrients
For kitchen use, we solve a critical flaw of RO reverse osmosis purifiers, their ultra-high precision removes not only bacteria, viruses, and residual chlorine but also essential minerals and trace elements from water.
For municipal tap water, ChengrongEra mineral-water-like kitchen water purifier eliminates harmful bacteria, viruses, and residual chlorine while preserving the water’s natural minerals and trace elements.
Similar kitchen ultrafiltration purifiers on the market also retain minerals, but due to structural defects, they use PS membranes instead of true 0.01-micron ultrafiltration membranes. While this ensures water flow rate, the lower precision fails to filter out bacteria, viruses, and residual chlorine.
Our ultrafiltration membranes with residual chlorine removal capability are a proprietary technology of Chengrong—setting a global benchmark for the industry.
ChengrongEra water purifiers truly purify water and enhance quality of life. I firmly believe that our product quality will live up to the trust customers place in Chengrong Ultrafiltration Factory and our emerging brand, ChengrongEra.

Chengrong Ultrafiltration Factory has specialized in stainless steel pipeline ultrafiltration water purifiers for 18 years. With 280 colleagues, we focus solely on perfecting one core product. Renowned as one of the top 3 factories in the industry, we stand as a full supply chain factory rarely matched in the pipeline ultrafiltration water purifier sector. Many first-tier water purifier brands, both domestic and international, after extensive searches, ultimately choose to cooperate with Chengrong Ultrafiltration Factory, simply because we can make them zero worries.
In 2025, Chengrong Ultrafiltration Factory finally launched its own brand, ChengrongEra, and began entering the consumer market (C-end). This move brings us closer to end-users, we hope to hear their authentic usage feedback, and manufacture better and better UF water purifiers.
