Therefore, we informed Ms. Wen that since the whole house water filter could not be installed, she only needed to schedule an SF Express doorstep pickup to return the ultrafiltration water filter unit directly to Chengrong Ultrafiltration Factory. She didn’t need to worry about shipping fees, as all return costs were borne by ChengrongEra.

Now I use water filtered by this kitchen under sink water filter at home, in my office and all company water stations. I am the most loyal user of our own products. I believe a product can only be recognized as qualified once it wins approval from myself, my family, colleagues and friends.

Most customers only have a one-sided understanding of whole house water filtration systems, like, urban residents generally believe a watrer filter is merely an under sink water filter installed in the kitchen. By contrast, rural customers tend to regard a water filter as a whole house water filtration system mounted on the main water inlet pipeline.

If you pursue premium quality and superior user experience, try ChengrongEra whole-house water filtration systems. We will never let you down and will deliver stable, reliable whole-house water treatment protection for you and your family.

SGS test results have confirmed that the ultrafiltration membrane filter cartridges independently developed and manufactured by Chengrong Ultrafiltration Factory fully comply with the NSF/ANSI 58-2023 standards, an achievement rarely matched by other manufacturers in the industry.

Over the past year, many customers of ChengrongEra Ultrafiltration Water Filters have run into problems with water filters simply because they lack a clear understanding of the overall whole house water filtration system design framework.

ChengrongEra is not a middleman or trader, but a technology-focused original factory. As one of China’s top 3 manufacturers in the R&D and production of ultrafiltration membranes and ultrafiltration water filters, our whole-house water filtration solutions help hundreds of thousands of households solve their cloudy water issues every year.

However, for turbid well water or stream water in rural areas, which contain large amounts of sediment and other impurities, high pressure will quickly clog the UF membrane. Once clogged, water flow decreases, shortening the membrane’s service life and harming the user experience. That’s why I keep emphasizing in my videos that the feed water pressure for ultrafiltration membranes used in a whole house water filtration system must not be too high.

Despite its high filtration precision of 0.1μm, ChengrongEra whole-house water filtration system do not reduce household water pressure. Drawing on 19 years of industry experience, I have developed two Chengrong Formulas, which allow customers to calculate the suitable membrane flux specification for their homes

So what defines the quality of an whole house water filtratiob system? For ChengrongEra, it boils down to three core aspects: manufacturing quality, product functionality, and structural design. That is why ChengrongEra could reach the top 1% quality in the industry.
