A friend of mine is moving to a new house soon and has been shopping for various household items lately.
She mentioned in our group chat yesterday that when she was looking at water purifiers while out, she found them to be quite a luxury—under-sink ones cost 5,000 to 6,000 yuan, and whole-house systems even go for over 10,000 yuan.
Another group member asked, "Are they reverse osmosis (RO) ones?"
My friend replied, "All of them are RO reverse osmosis water purifiers."
Actually, when it comes to brand-name RO reverse osmosis water purifiers, the end result is just H₂O. As for those conceptual features, opinions vary, but in my view, they’re all just "intelligence taxes"—though I’d never say that publicly, of course.
The market is the best filtering mechanism. The ultrafiltration (UF) water purifiers we manufacture at Chengrong have unique advantages, whether for whole-house water purification or kitchen-specific use. I believe good products will definitely be recognized by the market and ultimately by more and more users.
My friend has quite high standards for quality of life, but she never buys things randomly. She always does a round of market research first. Before deciding to buy a Chengrong Shidai water purifier, she visited our factory many times to see the facility and our products in person.
As she put it, "It’s not far anyway—I can get there with just a push of the gas pedal."
Sometimes I think, people like her totally deserve to be wealthy.
It also reminds me of a while back, a boss from Futian directly ordered an intelligent UF water purifier from us. The reason was that at his hometown in Luhe, Shanwei, the tap water would turn turbid every time it rained.
He tried using a PP cotton "big white bottle" filter, but found it ineffective. Moreover, after using it for a period of time, the water would easily develop an odd smell. Last time, he sent me a photo of the PP cotton filter at his hometown. Since the bottle is transparent and installed outdoors, the entire filter element looked green, yellow, and even a bit black.
I often say that PP cotton "big white bottle" filters not only fail to filter water effectively but also tend to cause secondary pollution. I’m not saying this just to sell our products—it’s really the case.
When the boss saw his PP cotton filter element in such a state, he directly placed an order with me for an intelligent ultrafiltration (UF) whole-house water purifier.
At that time, the boss said he just wanted to buy a water purifier that could truly solve the problem of "yellow muddy water". Second, it must be maintenance-free—he had no time for upkeep. Finally, it needed to be of good quality; he didn’t want to spend extra time dealing with issues after purchase.
He added, "The best after-sales service is no after-sales service at all."
So I told him, "Then you should just go for the intelligent UF water purifier. Once you set the parameters, you don’t need to worry about it anymore. And do you know what makes UF better than micro-filtration?
Its filtration precision is as fine as 0.01 microns—it can filter out bacteria and viruses in water, making the water cleaner for the elderly and children. At the same time, it retains minerals and trace elements in the water."
After the intelligent UF system was installed at his hometown in Luhe, the boss told me that his family members said they had never seen such clear water before. When using it to make tea, they even felt the taste was much better.
Unexpectedly, half a month later, the boss contacted me again, wanting to buy another intelligent UF water purifier and asking me to install a set for him in Futian District, Shenzhen.
He said the feedback from his hometown was extremely positive. At first, his elderly family members felt reluctant about the cost, but after seeing the improved water quality, they never mentioned the money again. They all said the water purifier worked great, and the water at home tasted much better than before—his parents were particularly happy.
That’s why he decided to have another set installed here in Futian, Shenzhen.
