My most peers always regard the whole house sediment filters as fast-moving consumer goods, just like the instant noodles, believing that strong sales performance depends on continuous advertising investment and traffic generation.
They insist that prices must be low enough to attract customers, as most of customers of whole house sediment filters reside in rural areas. They just don’t believe that there are rich buyers exist in rural markets, which value quality far more than a cheap price tag.
However, I do not agree with their business mind of winning consumers over simply with low prices.
In my opinion, what consumers truly demand is a reliable whole house sediment filter, which can effectively filter fine sediment, rust and other impurities from turbid well water or city tap water.
The cheap price tag is never what our customers really want.
Probably it is because I’m a factory owner, I know better than anyone else, lower prices inevitably mean cutting manufacturing costs, which to me is nothing but industrial waste.
Over the past 19 years, ChengRong Ultrafiltration Factory has secured its position as the core ODM/OEM partner for 5 of the global first-tier whole house sediment filter brands.
We are chosen, as we could invest an additional 3 million RMB annually into R&D compared to our competitors, achieving an unmatched level of quality in both ultrafiltration membranes and complete whole house sediment filter systems.
It is not because we play the low-price game, but because we deliver absolute reliability whole house sediment filters, impeccable service, and rock-solid trustworthiness at every step.
As the best whole home water filtration system, ultrafiltration filter systems deliver the highest level of filtration rating—down to 0.1 / 0.01 microns.
Unlike conventional whole house sediment filters, our ultrafiltration membranes can be regularly cleaned up to be reused, ensuring an exceptionally prolonged lifespan. ChengRongTimes offers a 5-year warranty on the filter elements of our whole house sediment filters—a gold standard that is virtually unmatched in the entire whole house water filtration system market.
In my opinion, the whole house sediment filters should be categorized as small household equipment. As long as it is equipment, performance reliability and stability, ease of maintenance, and a long service life must be prioritized.
Therefore, the quality positioning of ChengRongTimes is to achieve top 1% standard in manufacturing quality, product functionality, and structural design, with quality on par with world-leading brands.
For a small factory, which has focused on the ultrafiltration membrane and complete unit, we don’t have money to do paid marketing. What we can do is delivering TOP1% quality to our customers, who demand a effective whole house sediment filters to remove the sediments from the well water or tap water.
For whole house water filters, quality is the very foundation for our customers.
A whole house water sediment filter that could generate word-of-mouth must be a high-quality ultrafiltration water filter. Only ultrafiltration filter could ensure effective whole house water filtration: The most commonly used PP cotton provides only 5μm filtration rating, while ultrafiltration filters reaches 0.1μm. And only premium ultrafiltration filter guarantees an excellent customer experience.
So what defines the quality of an whole house sediment filter?
For ChengRongTimes, it boils down to three core aspects: manufacturing quality, product functionality, and structural design. That’s why we are committed to achieving top 1% industry performance in these three areas.
- Manufacturing quality ensures performance reliability and stability.
- Product functionality guarantees effective filtration performance, only 0.1μm filtration rating can achieve the filtration effect that our customer really want.
- Structural design is intended to make installation and maintenance convenient for our users.
Why ChengRongTimes whole house sediment filters are priced higher?
The reason is simple: our costs are much higher.
In China, there is a counter-intuitive reality that a high price tag doesn’t mean high profits. High price is always from the exceptionally high manufacturing costs, not the profit margin is thick.
ChengRongTimes ultrafiltration water filters are SGS tested and compliant with NSF/ANSI 58-2023 standards—something our competitors simply won’t do. There is hardly another manufacturer like ChengRong that places such an absolute, uncompromising focus on product quality and customer experience.
All raw materials used by ChengRong Factory are sourced from the world’s top-tier suppliers and are 100% eco-friendly. When it comes to the raw materials for ultrafiltration membranes, I can confidently guarantee that our premium configurations are unmatched by any domestic peer.
Furthermore, our filter elements leave zero chemical residues. While domestic competitors take shortcuts by using external chemical agents for membrane disinfection, we insist on a rigorous process: rinsing our finished ultrafiltration membrane fibers with purified water and sanitizing them with a specially formulated alcohol solution, to avoid any possible chemical residues.
Actually, in China, ultrafiltration water filters are mainly certified by water hygiene permits rather than SGS test reports.
Nevertheless, to give customers complete peace of mind, ChengrongTimes still invest heavily in having SGS conduct tests in accordance with the American NSF/ANSI 58-2023 standards.
I also know that there are many third-party testing institutions in China, but SGS does not allow falsification and guarantees authentic data.
Be moderate in personal conduct; leave no room for mediocrity in quality and positioning.
Either achieve lowest 1% in pricing — something ChengrongTimes is unable to do. Or achieve top 1% in quality, benchmarking against golbal leading whole house sediment brands — which is exactly what ChengrongTimes is pursuing.
A customer once asked: Shenzhen Chengrong factory used to focus only on the ODM/OEM business. Is ChengrongTimes your direct-to-customer brand? For whole house sediment filters, I only trust Chengrong Factory. As a top 3 ultrafiltration manufacturer, your quality is guaranteed.”
After receiving a positive reply, it was obvious that the customer felt completely assured about ChengrongTimes, and several days later, he placed an order with us.
I mean there is nothing brings greater satisfaction than earning the recognition of our customers.
