Why ChengRongTimes Refuses to Play “Word Games”
When I was very young, my father taught me the importance of being a reliable person. And what’s he always said is that a man’s greatest strength is keep his word. Even if something is said in jest, you must follow through.
In short, you must either be cautious with your words or absolute in your commitment.
To me, reliability means delivering on every promise. And if an unexpected obstacle arises, you must communicate openly and immediately.
I still vividly remember our early days in business.
The company was struggling, and as the year-end approached, we didn’t have enough cash flow to pay our suppliers. My wife and I decided to visit them in person to apologize. To our surprise, our key supplier was incredibly understanding. That mutual trust laid the foundation for a partnership that has lasted for over a decade with our Chengrong Ultrafiltration Factory.
As Chengrong Ultrafiltration Factory grew, we gradually gained a reputation in the whole house water filter industry, and our suppliers also became more widely known.
I think the same applies to branding and marketing: reliability should be paramount.
Where expertise is possible, it must be done professionally, avoiding blind exaggeration. Marketing should also be based on credibility.

The 8T/10T Flow Rate Myth: Exposing the “Word Games” in the water flow of whole house water filters
Thanks to social media marketing, more and more users realize that ultrafiltration water filter is actually the best choice for whole house water filters.
However, my whole house water filtration systems and ultrafiltration water filter vendors, in order to alleviate customer concerns about water pressure and flow rate, just play word games with lay customers.
Take the example of the flow rate of whole house water filters, that made of ultrafiltration water filter.
For example, they tell customers their whole house water filters have a flow rate of 8t/h or 10t/h. Lay person, seeing such high flow rates with such low price, assume it must be good, and then place an order.
But I believe the most important thing in business is honesty and integrity.
At Chengrong, we refuse to take advantage of customers who are unfamiliar with the technical realities of whole house water filters. As, we know they will eventually figure it out.
In reality, 99% of household main pipes, even without a whole house water filters, have a maximum flow rate of only around 4 tonnes, far from the so-called 8 or 10 tonnes. This is because city tap water pressure is constant, and so are pipe sizes, which are limited to 4-inch, 6-inch, and 1-inch pipes. Consequently, the upper limit of water flow is also constant.
This upper limit is roughly 4-5 tons of water.
So, in our view, telling customers that your whole house water filter can produce a water flow rate of 8 or 10 tons per hour isn’t just a matter of false labeling.
The whole house water filters sold by ChengRong Times will also reflect my character, and it is also a matter of integrity.

What Do 8t/h and 10t/h Actually Mean? Understanding Membrane Flux of whole house ultrafiltration water filters
So what are these 8T and 10T?
It refers to the water filtration capacity of the whole house water filters, which in our ultrafiltration water filter industry is known as membrane flux.
For whole house water filter made with ultrafiltration water filter, the membrane flux is mainly determined by membrane quality and surface area.
For example, wh our Chengrong Ultrafiltration Factory are so dedicated to ultrafiltration membrane R&D?
It is because the ultrafiltration membrane from external suppliers are either extremely expensive or of poor quality, failing to meet the quality standards of Chengrong Ultrafiltration Factory.
After 10 years of R&D, our ultrafiltration membranes have achieved:
- 40% higher mechanical strength and toughness year-on-year.
- 40% to 50% higher flux under the same working condition.
- Superior resistance to fouling and clogging that stuns even global first-tier brands.
However, these are not the focus today.
What I wanna say is that membrane flux of whole house water filter is not equivalent to water flow rate.
Under normal circumstances, water flow rate will never reach 8T or 10T, as household water pressure and pipe size are constant.
However, membrane fluxes of 8T or 10T are possible, as long as the membrane area is large enough.
What’s more, because Chengrong’s self-developed ultrafiltration membranes are of superior quality, we can achieve these same high fluxes with significantly less membrane area. Ultimately, this allows our customers to lower their sourcing costs without compromising on quality.”
The benefits of a high mambrane flux
What are the benefits of a high membrane flux?
It ensures that even if you open multiple faucets at home, the water pressure remains constant, preventing it from decreasing and causing a poor user experience.
Membrane flux refers to the water production capacity of a whole house water filter, similar to a blood-forming organ that continuously delivers a constant flow of water at a constant pressure into household pipes.
Water production capacity must always exceed water consumption to ensure a sufficient supply of water in the pipes.
Therefore, in theory, a larger membrane area is better.
However, a larger membrane area inevitably increases manufacturing costs.
Please don’t worry, ChengRong Times has struck the perfect balance between a premium water experience and cost-efficiency.
