Chengrong Factory was established on May 6, 2008. It's one of the last few factories that cover the whole supply chain for ultrafiltration membranes and UF water purifiers. By 2026, Chengrong Factory has long become the benchmark for peers worldwide.
Because we always put R&D first, update products nonstop, and have customers' backs. Out of nearly 4,000 industry peers in China, fewer than 10 have got the "National High-Tech Enterprise" title, and Chengrong factory is one of them.
Four unique ultrafiltration water filter lines:
1. Under-sink water filter for Drinking: Could retain natural minerals and trace elements in drinking water, which is an advantage that RO water purifiers cannot achieve
2. Whole house water filtration system: Installed on the main water inlet pipeline, effectively intercept sediment, rust, and other particulate impurities, filtering tap water, turbid well water and muddy water to crystal clarity, providing much cleaner water for the entire home.
3. Commercial ultrafiltration water filter for whole house water filtration or drinking: Provide clean and healthy drinking water for schools, offices, hotels and other commercial places, while retaining natural minerals and trace elements in the water, which is an advantage that RO water purifiers cannot achieve.
4. Complete set of water purification equipment for water treatment plants: With customization options to produce natural minaral retaining water, purified water, and ultrapure water, tailored to meet specific client requirements.
Chengrong factory is used to conducting 3 to 4 technical upgrades annually, ensuring Chengrong's ultrafiltration membrane & filtration technology far ahead of our peers in the quality.
The reason Chengrong has grown to become one of the top 3 ultrafiltration water filter factories today is that, over the past nearly 20 years, Mr. Zhuang Beikan, the founder, has run the factory with the core value of "Integrity as Pride". His goal is to ensure Chengrong's customers sleep soundly, helping them increase market profits by 10%. He has truly turned the concept of "zero customer worries" into reality.
From its early days, when Chengrong Factory focused on manufacturing hardware parts, processing stainless steel casings for ultrafiltration water filters, which is always used for whole house wtaer filtration system to filter rural well water, then providing ODM/OEM services for complete ultrafiltration water filters, all staff have adhered to the ISO 9001 international quality certification system, with an annual investment of over 360K RMB into quality checks. This is why ChengrongEra UF filter as whole house water filtration system will be no leakage and no rust for 10 years.
Later, the factory established our own ultrafiltration membrane facility, and further expanded into the engineering sector, covering commercial ultrafiltration water filtration equipment for urban water treatment plants.
Starting as a small workshop with only 10 employees, it has grown into a full-supply-chain factory with 280 staff, a feat rarely matched by any other factory in the industry.
In 2025, Chengrong Ultrafiltration Factory launched its own brand: ChengrongEra(诚荣时代®), targeting the top 2% high-end market. In manufacturing quality, product functionality, and structural design, ChengrongEra has already become a benchmark that global ultrafiltration industry peers strive to match.
