What Is a Complete “Mineral-Water-Like” Whole-House Water Filtration System?
Many customers actually have a relatively one-sided understanding of whole-house water filtration.
For example, urban customers always think that a water filter is an under-sink water filter installed in the kitchen; while when you talk to rural customers about water filters, they often think that a water filter is a whole-house water filter installed on the main water inlet pipe.
In fact, a complete whole-house water filtration system should include both whole-house water filtration equipment installed on the main water inlet pipe and an under-sink water filter installed in the kitchen.
The whole-house water filtration system installed on the main water inlet pipe is mainly used to improve the water quality throughout the entire household. In other words, daily water use such as bathing, washing clothes, washing dishes, and washing vegetables can all be improved, while also ensuring the cleanliness of the internal household pipelines and extending the service life of water-using appliances.
The under-sink water filter installed in the kitchen is mainly used for drinking water and cooking water, while further ensuring better drinking taste.
The reason why this customer chose the ChengrongTimes® mineral-water-like water filter is that she has a baby at home and pays relatively more attention to drinking water health. The ChengrongTimes® mineral-water-like water filter can ensure that the purified water produced is clean and healthy, so she ultimately chose us.
In addition, unlike many competitors, ChengrongTimes conducted a large number of tests to verify the performance and safety of the mineral-water-like water filter.
We not only have an official water-related approval document (Approval No.: 粤卫水字（2026）-02-第S0177号), but also have an SGS test report to prove the material safety of Chengrong ultrafiltration membrane filter cartridges, because our filter cartridges comply with the NSF/ANSI 58-2023 standard.
In addition, we commissioned the Shenzhen Academy of Metrology & Quality Inspection, which conducted direct-drinking water testing according to China’s CJ/T 94-2005 standard. The test results show that ChengrongTimes® mineral-water-like water meets the direct-drinking water standard.
In addition to being extremely costly, the above tests also impose extremely strict quality requirements on the water filter itself.
Many water filter companies on the market do not conduct these tests for two reasons. First, they are unwilling to invest this cost; second, even if they spend the money, they may not be able to pass the tests unless they falsify the data.
However, ChengrongTimes not only passed all of these tests, but passed all of them on the first attempt, which is difficult to find a second company that can achieve this in the industry.
For safe tap water, ChengrongTimes mineral-water-like water can not only remove 99.99% of bacteria, viruses, residual chlorine, and other particulate impurities from the water, but also retain the natural minerals and trace elements in the water. It is not only clean and suitable for direct drinking, but also healthier.
This is because ChengrongTimes is a factory brand that has achieved the TOP 1% in the industry in terms of manufacturing, product functions, and structural design. Its factory, Shenzhen Chengrong, has been engaged in the stainless steel pipeline ultrafiltration field for 19 years and ranks among the top three in the industry.
Because of this, I have confidence in our raw materials, semi-finished products, processes, and technologies.
The core filtration material of the mineral-water-like water filter—the residual-chlorine-removing ultrafiltration membrane—is Chengrong’s proprietary technology, and there is no second company in the world.
Even leading brands around the world cannot remove residual chlorine, but Chengrong’s residual-chlorine-removing ultrafiltration membrane has achieved this.
After being filtered through the residual-chlorine-removing ultrafiltration membrane, the purified water cannot be detected even by the most sophisticated instruments, so it can indeed achieve the effect of mineral-water-like water.
In addition, unlike the commonly used water purification sequence in the industry of “first passing through an ultrafiltration membrane/RO reverse osmosis membrane to intercept impurities, and then passing through activated carbon to improve the taste,” ChengrongTimes adopts a completely different structural design:
First, the water passes through activated carbon fiber to improve the taste, and then passes through the residual-chlorine-removing ultrafiltration membrane to completely intercept bacteria, viruses, residual chlorine, particulate matter, and other impurities in the water.
Many people may not know that activated carbon can both adsorb residual chlorine in water and improve the taste of water, but it is also very prone to bacterial growth.
Therefore, this innovative structural design of ChengrongTimes can prevent activated carbon from causing secondary contamination of purified water while improving the taste of the water.
This is also one of the reasons why our mineral-water-like water can be both clean and healthy.
The customer also truly understood our structural design from the perspective of product logic after listening to our detailed explanation.
In addition, whether it is the activated carbon fiber used to improve taste or the core filtration material, the residual-chlorine-removing ultrafiltration membrane, the quality of the filter media we use is benchmarked against leading international brands, and the amount used is 2~3 times that of competing products on the market.
It is precisely based on these technologies, materials, structural designs, and testing data that the customer ultimately developed sufficient trust in the ChengrongTimes® mineral-water-like water filter.
Chengrong Ultrafiltration, customers have never had any concerns
No rust for ten years
No water leakage for ten years
After-sales service for ten years as well
ChengrongTimes® water filter never compromises on quality
The residual-chlorine-removing ultrafiltration membrane is Chengrong’s proprietary technology, with no second company in the world. It is also the core filtration material of the ChengrongTimes® mineral-water-like water filter. With a filtration precision of 0.01 microns, it intercepts 99.99% of impurities, bacteria, viruses, and residual chlorine in water, while retaining the natural minerals and trace elements in the water. ChengrongTimes® mineral-water-like water provides clean and healthy direct-drinking water.
