I’ve always believed that for whole house water filtration system, an ultrafiltration (UF) water filter is the only effective option.
Other types of whole hosue water filtration systems, in my opinion, are nothing but a waste of money. Because their filtration precision is low, they can only offer psychological comfort without any real effect.
However, I rarely voice this opinion publicly. It feels like I’m bragging about my own products, and people might think I’m being dishonest. But I know that even if I didn’t produce ultrafiltration water filters myself, I would still maintain that ultrafiltration water filter is the best choice for any whole house water filtration system.
The reason is simple: the ultrafiltration water filter has the highest filtration precision among all of whole house water filtration systems.And unlike most brands used multi-stage whole house water filtration, ChengrongEra adopts technologically upgraded single-stage whole house water filtration system. Smaller space occupied, at least 50X finer filtration precision. ChengrongEra whole house water filtration system can really intercept sediment, rust, colloids, insect eggs and other impurities to the greatest extent. Even muddy yellow water from rural areas can be filtered crystal clear.
For municipal tap water, using an ultrafiltration water filter in your whole house water filtration system is almost effortless. Yet traditional filters used in a whole house water filtration system, with their larger pores, often fail to capture fine particulate impurities in tap water.
What’s more, besides its high filtration precision, the ultrafiltration water filter won't reduce household water pressure and has a longer service life for its filter cartridge. When I use the UF water filter in a whole-house water filtration system, I don’t just see it as a water filter— I regard it as a miniature water treatment plant euipment.
In my videos, I have always mentioned that the ultrafiltration water filter has “four fears”:
- Fear of excessively high water pressure
- Fear of overly long continuous filtration
- Fear of colloids
- Fear of bacterial colonies
A viewer was planning to install an ultrafiltration water for his whole house water filtration system. After watching my video, he learned that UF filters cannot withstand excessively high water pressure. Otherwise, fine impurities like sediment, rust and colloids would be forced by high pressure to quickly clog the micro-pores of the UF membrane.
City tap water is pre-treated by water plants and has good quality, so slightly higher pressure has little impact on ultrafiltration membrane fouling. However, for turbid well water or stream water in rural areas, which contain large amounts of sediment and other impurities, high pressure will quickly clog the UF membrane. Once clogged, water flow decreases, shortening the membrane’s service life and harming the user experience. That’s why I keep emphasizing in my videos that the feed water pressure for ultrafiltration membranes used in a whole house water filtration system must not be too high.
Ultrafiltration is fundamentally different from RO membranes. RO is a semi-permeable membrane that requires added pressure to push water through. In contrast, UF separates water from impurities using 0.1‑micron micro-pores. It can operate normally with just 1 bar of water pressure. Therefore, excessively high water pressure will only damage the ultrafiltration membrane.
