Why ChengrongTimes Is a Smarter Choice for Whole House Water Filtration System?
For most homes, 0.1 μm ultrafiltration water filter is all the whole house filtration they actually need
What conventional 1~5 μm whole house water filtration systems miss is exactly why whole house ultrafiltration matters. With 0.1 μm filtration rate, ChengrongTimes captures 99.99% suspended particles, rust and colloids before they circulate through your home.
1) 0.1 μm Filtration Rating Without Stacking More Stages
Instead of stacking multiple stages to make up for coarser sediment filtration, ChengrongTimes starts directly with 0.1μm ultrafiltration—a filtration rating 10–50× finer than conventional 1~5 μm PP sediment filters.
2) No Noticeable Pressure Drop
A large effective ultrafiltration membrane area and up to 40% higher membrane flux help maintain the flow your whole home needs with no noticeable pressure drop. Finer filtration doesn’t always mean weaker water flow, especially for ChengrongTimes.
3) 5-Year Membrane Warranty, Fewer Filter Replacements, Lower Long-term Cost
ChengrongTimes ultrafiltration membrane cartridges are washable and reusable, designed for long-term use and backed by a 5-year membrane cartridge warranty, potentially saving hundreds of dollars over five years.
4) More Effective Solutions to Membrane Fouling — Simple Enough for DIY Cleaning
ChengrongTimes unique structural design for the whole house water filtration system makes ultrafiltration membrane cleaning easier and more thorough, helping restore water flux and maintain strong, stable water flow over time.
5) SGS Tested & Verified to Meet NSF/ANSI 58 Standards — Rare in our industry
ChengrongTimes PVDF/PVC ultrafiltration membranes are rarely matched by domestic peers across 6~7 key performance metrics, with overall quality on par with leading global brands — at 30~40% lower cost.
6) 316L Stainless Steel — Built for 10 Years, Indoors or Outdoors
ChengrongTimes refuses to compromise on quality, choosing 316L stainless steel over conventional 304 for superior corrosion resistance and long-term durability — even global leading brands cannot match
