0.1μm PVDF Ultrafiltration for Crystal-Clear Water Throughout the Home
- 10–50× Finer than Typical PP Sediment Filters
0.1 μm ultrafiltration water water filter could capture much finer impurities that conventional 1–5 μm PP filters would miss in municipal and well water. - 0.1μm Filtration Improves Water Quality Throughout the Home
Effectively blocks sediment, dirt, sand, rust, colloids and fine suspended particles, while also blocking most common bacteria—making the water not only clearer, but cleaner. - Turns Turbid Water into Crystal-Clear Water at the Main Inlet
Delivering crystal-clear water to every tap while keeping plumbing and water-using appliances cleaner, helping them last significantly longer.
High Flow with No Noticeable Pressure Loss — 10-50× Finer Filtration Without Sacrificing Flow, Few Competitors Can Match
- 60% Higher Water Flux Under the Same Operating Conditions
Chengrong’s proprietary reinforced PVDF membrane delivers 60% higher flux under the same operating conditions — a performance few competitors can match. - Chengrong Formula — Zhuang’s Membrane Flux Sizing Method
Developed by Beikan Zhuang, founder of Chengrong Ultrafiltration Factory, this quantitative sizing method matches a household’s water demand with the required membrane flux, helping achieve high flow with pressure drop approaching zero. - Real Membrane Flux Capacity, Not Inflated Flow Claims
We evaluate each cartridge by its actual membrane flux to reflect its true filtration capacity—not by an inflated outlet flow rating that is unrealistic under normal household conditions.
Chengrong Formula
A Scientific Way to Size Your Whole House Ultrafiltration Water Filter1. Homes with a Water Tank
Minimum membrane capacity = Daily household water use × 5,
or, Minimum membrane capacity = 200 L/person/day × Maximum users × 52. Homes Without a Water Tank
Minimum membrane capacity = 300 L/h × Number of frequently used outlets × 5
Built for 5+ Years of Reuse — Without Frequent Cartridge Replacement
- Filtered-Water Backwashing + Hand Cleaning at the Same Time
Filtered water backwashes the membrane from the inside while the outside is cleaned by hand, flushing out contaminants trapped in the 0.1 μm membrane pores and removing buildup from the PVDF membrane surface.
Conventional cartridges, by contrast, can only remove surface buildup through manual cleaning. - No Cartridge Removal Required — Easy for Anyone at Home to Operate
No cartridge removal, no special tools, and no complicated procedures—simple enough for everyday homeowners to maintain - 40% Higher PVDF Ultrafiltration Membrane Strength & Toughness
Designed to withstand repeated backwashing and manual cleaning for long-term reuse — backed by a 5-year cartridge warranty.
No Membrane-Related Odor in Filtered Water & SGS-Tested for Material Safety
Tested by SGS according to relevant NSF/ANSI 58-2023 requirements, ChengrongTimes membrane materials are designed for clean, odor-free water contact, with no harmful substance migration detected within the tested parameters — a level of material safety rarely matched in the industry.
316L Stainless Steel Housing — Built for 10+ Years Indoors & Outdoors, A Standard Few Competitors Can Match
- 100% Polished Inside & Out + High-Temperature Ultrasonic Cleaning
Every ChengrongTimes housing is 100% polished inside and out and then ultrasonically cleaned at high temperature to remove manufacturing residues and ensure a clean, hygienic water-contact surface — a process rarely seen in conventional housings. - Double-Sided Weld Formation — Built for 10 Years of Rust-Free, Leak-Free Performance
Strong, uniform welds on both sides provide greater pressure resistance and help prevent corrosion, leakage and discoloration, built for 10 years of rust-free, leak-free performance — with workmanship rarely matched in the industry. - 400,000+ Pressure Cycles — Over 4× the National Standard Requirement
ChengrongTimes whole house water filter housing has withstood more than 400,000 dynamic pressure cycles, exceeding the 100,000-cycle requirement of GB/T 30307-2023 by more than 4 times — demonstrating exceptional pressure resistance, structural durability and long-term leak resistance.
