Why do we state 0.1 \u03bcm when others advertise 0.01 \u03bcm?
Because accurate specifications matter more than impressive numbers.

At ChengrongTimes, we never mislead our customers or take advantage of what they may not know.<\/p>\n<\/div>\n\n\n\n

As a specialized ultrafiltration water filter manufacturer with a fully integrated supply chain, Chengrong Factory launched ChengrongTimes<\/strong>, our factory-direct brand for end customers, in mid-2025.<\/p>\n\n\n\n

Over the years, our focus on the R&D and manufacturing pof ultrafiltration membranes and water filters has given us extensive experience in water purifier system for home, which make it difficult to find a second factory as professional as ChengrongTimes. <\/p>\n\n\n\n

Thus, we have received many questions from customers\u2014often after they have encountered confusing or even contradictory claims in the real use of ultrafiltration water purifier system for home.<\/p>\n\n\n\n

One of the most common questions is about the filtration rating of reinforced PVDF membranes<\/strong> used in the whole house water filtration system<\/strong><\/a>.<\/p>\n\n\n\n

Is it 0.01 \u03bcm or 0.1 \u03bcm?<\/strong><\/p>\n\n\n\n

Many brands on the market advertise a filtration accuracy of 0.01 \u03bcm<\/strong> for reinforced PVDF ultrafiltrtaion membranes used in their water purifier systems for home. Yet ChengrongTimes, backed by one of the TOP 3 ultrafiltration manufacturers in the industry, states 0.1 \u03bcm<\/strong> for the reinforced PVDF membranes used in our systems.<\/p>\n\n\n\n

This leaves many homeowners looking for a water purifier system for home<\/strong> with a simple but important question:<\/p>\n\n\n\n

Who should they believe?<\/strong><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n

Can Denser Fiber Packing Turn a 0.1\u03bcm PVDF Ultrafiltration Membrane into a 0.01\u03bcm? Of Course Not!<\/strong><\/h2>\n\n\n\n
\n
\n
\n

A user once told us that one of our peers claimed that their reinforced PVDF ultrafiltration membrane used in the water purifier system for home could achieve a filtration accuracy of 0.01 \u03bcm.<\/p>\n\n\n\n

Because their membrane fibers were packed more densely. <\/p>\n\n\n\n

But what does \u201cdenser membrane fibers\u201d actually mean? <\/p>\n\n\n\n

It simply means that more membrane fibers are packed within the filter cartridge. Increasing the number of membrane fibers increases the total effective membrane area. <\/p>\n\n\n\n

It would never automatically change the pore size of the PVDF ultrafiltration membrane from 0.1 \u03bcm into 0.01 \u03bcm.<\/p>\n\n\n\n

A simple analogy may make this easier to understand:<\/p>\n\n\n\n

“A bucket may contain more water than a bowl, but that does not mean the water in the bucket has a higher density. Similarly, 1 kg of iron and 1 kg of cotton have the same weight, even though their volume and physical characteristics are very different.”<\/p>\n\n\n\n

The same principle applies to reinforced PVDF ultrafiltration membranes used in the water purifier system for home. <\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n

Why ChengrongTimes Chooses Accuracy Over Impressive Claims? As Trust begins with honesty<\/strong><\/h2>\n\n\n\n
\n
\n

Why do ChengrongTimes specify a filtration accuracy of approximately 0.1 \u03bcm for our hand-washable whole house water filter<\/strong><\/a> made of reinforced PVDF ultrafiltration membrane cartridge? <\/p>\n\n\n\n

ChengrongTimes is different from our peers. We often say this to our customers, and it is one of the key reasons why ChengrongTimes stands apart in the industry.<\/p>\n\n\n\n

Backed by 19-year Chengrong Factory\u2014one of the TOP 3 manufacturers in the ultrafiltration water filter industry with in-house ultrafiltration membrane R&D and complete water purifier system for home manufacturing capabilities\u2014We believe that accurately stating every product specification is not something to boast about. It is simply the most basic responsibility we owe our customers.<\/p>\n\n\n\n

By presenting our ultrafiltration membrane cartridge specifications as they actually are, we also hope to correct the exaggerated specifications that have become common in the industry.<\/p>\n\n\n\n

We understand that honest numbers may make our ultrafiltration water purifier system for home look less impressive at first\u2014especially when they are compared with seemingly better specifications advertised elsewhere. But we believe that, over time, honesty and professional expertise will earn us something far more valuable: the trust of our customers.<\/p>\n<\/div>\n\n\n\n

Frequently Asked Question About
Ultrafiltration Water Purifier Systems for Home<\/strong><\/h2>\n\n\n\n
\n
\n

Q: <\/strong>
Can Reinforced PVDF Ultrafiltration Membranes Achieve a 0.01 \u03bcm Filtration Rating?<\/strong>

A: <\/strong>
At Chengrong Factory, achieving a filtration rating of approximately 0.1\u20130.15 \u03bcm<\/strong> with our reinforced PVDF membrane is already the result of extensive investment in membrane formulation, manufacturing processes, and years of continuous optimization.

If a manufacturer claims a 0.01 \u03bcm filtration rating<\/strong> for a reinforced PVDF ultrafiltration membrane, the real question is not how impressive the number sounds, but how that number was measured and verified<\/strong>.

If the claim cannot be supported by reliable test data, it may simply be an overstated specification.<\/p>\n<\/div>\n<\/div>\n\n\n\n
