Building a brand, especially for reliable and long-lasting home ultrafiltration water filters, means creating real value for customers — not just acting as a middleman chasing price differences. We must devote 300% effort to pursue perfection in quality and service, rather than worrying that high costs and fair prices will drive consumers away or make our efforts meaningless.

Although ChengrongEra ultrafiltration water filters do not carry official NSF certification, we randomly sample and test our products through SGS, strictly following the requirements of NSF/ANSI 58-2023. This approach is more rational and responsible—both to our brand and to our customers.

Want to know the strength of Chengrong Factory, one of the top 3 in the UF water filter industry? Just look at ChengrongEra UF water filters. They represent the peak of manufacturing and R&D capabilities of Chengrong Ultrafiltration Factory.

Because only the 0.01 μm PVC internal-pressure ultrafiltration membrane can block bacteria and viruses as a whole house water filter, however, the 0.1 μm PVDF reinforced membrane (often used in hand-wash whole-house filters) cannot, even if some sellers falsely claim 0.01 μm precision.

For rural self-built houses, we usually recommend the manual-cleaning whole house UF water filter, installed on the main water inlet pipe as the first barrier for whole-house water purification. It filters sediment, mud and other particles, keeping the water from the taps clear and not cloudy.

It is this post-positioned activated carbon filter element that causes the common problem of bacterial exceeding standards in water purifiers.

Our engineer would design a professional customized installation plan based on each customer’s actual situation. This ensures that no matter the plumber's level of expertise, following the detailed installation drawings will almost eliminate installation errors.

There are only two types of filter cores used in kitchen water purifiers for direct drinking: 0.01μm PVC ultrafiltration (UF) membranes and 0.1nm reverse osmosis (RO) membranes. They determine the properties of the purified water produced.

The filtration accuracy of an ultrafiltration membrane is primarily determined by its material. Whether reinforced or non-reinforced, the filtration accuracy of PVDF membranes always fluctuates around 0.1 μm, far from reaching 0.01 μm, this is an inherent property determined by the material itself.

ChengrongEra is no longer a blank slate in the minds of our target customers, we already have our own brand label: premium pricing.
