I’ve always believed that an ultrafiltration water filter is the most effective option for a whole house water filtration system.
In my opinion, other types of home water filter systems are simply a waste of money. Because of their low filtration ratings, they often provide little more than psychological comfort without delivering meaningful filtration results.
However, I rarely express this opinion publicly.
Since it can sound as though I am bragging about my own products, and some people may think I am being dishonest. But even if I did not manufacture ultrafiltration water filters myself, I would still believe that a UF water filter is the best choice for a whole home water filter system.
The core advantage is straightforward: UF membranes deliver far finer filtration than conventional whole-house filters. While most brands rely on bulky multi-stage setups, ChengrongTimes engineered an upgraded single-stage filtration unit. It saves installation space and features a 0.1μm pore size—at least 50 times finer than standard PP sediment filters.
ChengrongTimes whole home water filter system can effectively remove sediment, rust, colloids, insect eggs and other impurities. Even muddy yellow well water from rural areas can be filtered to be crystal clear.
For municipal tap water, it is much more effortless for ChengrongTimes ultrafiltration whole home water filter system.
However, traditional sediment filters with much lower filtration rating often fail to capture fine particulate impurities in tap water.
In addition to its high filtration precision, a properly designed UF water filter causes little loss of household water pressure and generally provides a longer filter cartridge service life.
When I use a ChengrongTimes UF water filter as a whole home water filter system, I do not see it as simply a water filter, I regard it as a miniature water treatment equipment.
In my videos, I have often mentioned that ultrafiltration water filters have “four fears”:
- Fear of excessively high water pressure
- Fear of excessively long periods of continuous filtration
- Fear of colloids
- Fear of bacterial colonies
One viewer was planning to install an ultrafiltration filter as his home water filter system.
After watching my video, he learned that ultrafiltration filters should not be exposed to excessively high water pressure. Otherwise, fine impurities such as sediment, rust and colloids may be pushed against the ultrafiltration membrane by the high pressure, quickly clogging its micropores.
Municipal tap water is pretreated by water plants and generally has good water quality, so slightly higher pressure has a limited impact on UF membrane fouling.
However, turbid well water or stream water in rural areas may contain large amounts of sediment and other impurities. Under high pressure, these impurities can quickly clog the UF membrane.
Once the ultrafiltration membrane becomes clogged, the water flow decreases, shortening its service life and negatively affecting the user experience. That is why I repeatedly emphasize in my videos that the feed-water pressure of an ultrafiltration membrane used in a whole home water filter system should not be too high.
The viewer then asked whether his household water pressure of 3 bar was suitable for a home water filter system using ultrafiltration membranes.
I answered that 3 bar is acceptable for ultrafiltration membranes.
Furthermore, the UF membranes manufactured by ChengrongTimes use premium raw materials that outperform many comparable products. Three key components are sourced internationally, and as of 2026, we have never stopped researching and improving our UF membrane material formulas. The membranes from Chengrong Factory offer approximately 40% greater toughness and strength than comparable products on the market.
Ultrafiltration is fundamentally different from reverse osmosis.
An RO membrane is a semi-permeable membrane that requires additional pressure to push water through it. In contrast, UF membrane separates water from impurities through the micropores of the membrane.
