ChengrongEra intelligent UF water filter features 0.01μm filtration precision, effectively blocking bacteria and viruses. After placing a trial order half a year ago, Mr. Zheng placed a repeat order for 6 units

Last week, Mr. Zheng from Henan, China sent me a message.

He said that the ChengrongEra Intelligent Touch-Screen Model Whole-house Ultrafiltration Water Filter his client purchased last August has been working extremely well, so he is placing another order for 6 units this time.

Mr. Zheng from Henan and I are both veterans in the water treatment and filtration indust, The difference is that he runs a physical store and deals directly with end-users, while I manage a factory that mainly supplies distributors of various ultrafiltration water filter brands.

Without the ChengrongEra brand, I probably would never have dealt directly with end customers in my entire career. However, I’m glad I launched the ChengrongEra brand. Previously, I only understood the needs of B-end clients and knew very little about C-end consumers. Now I’ve realized that B-end and C-end demands for ultrafiltration water filter are completely different.

Mr. Zheng told me that the brand positioning of ChengrongEra is spot-on. As one of the TOP 3 factories in the ultrafiltration water filter industry, we ought to produce TOP 1% high-quality UF water filters. Wealthy consumers today don’t care much about price; they prioritize quality living, and as long as the product is reliable and durable, cost is not an issue.

Although Mr. Zheng runs a brick-and-mortar business in a county-level city in Henan, he has plenty of high-net-worth clients. It makes sense—household water filters are not daily necessities, so households that choose to buy one in a county-level area are definitely financially well-off.

Why do I insist on making ChengrongEra’s manufacturing quality, product functions and structural design among the top 1% in the ultrafiltration water filter industry, with quality on par with or even higher than global first-tier brands? It’s all because of these price-insensitive customers.

ChengrongEra Intelligent Touch-Screen Model Whole-house Ultrafiltration Water Filter is not cheap, but their advantages are obvious. It requires no manual maintenance, and features higher filtration precision. They not only clarify turbid well water in rural areas and municipal tap water, but also filter out bacteria and viruses from raw water.

While most ultrafiltration water filters on the market claim a filtration precision of 0.01μm, in reality, only PVC internal pressure membranes, which adopt an inside-out filtration method, can achieve a true 0.01μm filtration precision. In contrast, PVDF external pressure membranes, which adopt an outer-in filtration method—the type with hand-washable filter cartridges—only have an actual filtration precision of 0.1μm. Even so, 0.1μm precision is sufficient to trap all impurities—including sediment, rust, colloids, and insect eggs—from turbid rural well water, mountain spring water, and muddy water, leaving the filtered water clear and transparent. This is why false labeling can be common: customers only notice the clearer water, cannot see bacteria or viruses, and thus usually do not drink it directly anyway.

However, a precision of 0.1μm is insufficient to block bacteria and viruses. To achieve effective microbial removal, a genuine ultrafiltration membrane — 0.01μm PVC internal pressure membrane — is essential.

While PVC internal pressure membranes cannot be manually washed, filter clogging can be easily addressed through proper flushing and backwashing, ensuring hassle‑free operation. ChengrongEra intelligent touch-screen whole-house ultrafiltration system is equipped with an intelligent digital control system and Chengrong’s proprietary cleaning technology. We have successfully solved the fouling issue that has long plagued the industry, a challenge many competitors still fail to overcome.

As a professional UF manufacturer, our entire factory focuses exclusively on ultrafiltration products, allowing us to deliver superior performance and reliability.

Although priced slightly higher, our customers prioritize effective filtration, stable performance, and easy maintenance for their main water-supply whole-house systems — not just the cost.

On Mr. Zheng’s recommendation last year, his client placed an order for one ChengrongEra intelligent touch-screen whole-house ultrafiltration system. It provides a one-stop solution: clarifying turbid well water, removing bacteria and viruses, and featuring a low‑maintenance design with intelligent control and automatic operation. As this client had no time or energy for maintenance, and didn’t want to trouble his family either. Being well-off, saving a few thousand yuan meant little to him.

After more than six months of use, the family’s water experience improved dramatically, earning unanimous praise from everyone.

Word of ChengrongEra ultrafiltration water filter effect must have spread among Mr. Zheng’s clients. This time, instead of a small trial order, he placed a bulk order of 6 whole-house intelligent ultrafiltration water purifiers in one go.
