1. Installed on the whole-house main water inlet pipeline, the 0.1μm water filtration system clarifies turbid well water, rural muddy water, and municipal tap water to crystal clarity.
With a filtration precision of 0.1 μm, this whole-house water filter thoroughly removes sediment, rust, colloids, insect eggs, and other fine particles from incoming water. It keeps the inner walls of household pipelines clean, extends the service life of water appliances, prevents clothes from yellowing, and keeps showerheads clog-free. With 400× higher precision than traditional pre-filters, it delivers strong filtration without reducing water flow.
2. Three Core Advantages, Solve the long-unresolved industry pain point of manual cleaning for PVDF outer-in membranes, a unique solution rarely found in the market.
1) Intelligent High-Speed Forward & Reverse Spin Cleaning Technology: developed independently by Chengrong factory, inspired by the cleaning principle of front-loading washing machines.
2) No disassembly, No Manual Washing Required: ChengrongEra thoroughly solves the industry pain point that PVDF outer-in membranes require regular manual cleaning, more friendly to the users.
3) Users can freely set the cleaning interval and duration according to their own water quality, making it suitable for different water conditions.
3. ChengrongEra UF filter cartridge is tested by SGS and complies with NSF 58-2023 standards. It features a service life of 2–3 years, offering a level of quality and reliability you won't find anywhere else.
The ultrafiltration membrane is independently developed and manufactured by Chengrong, effectively preventing fiber breakage during spin cleaning. Our proprietary membrane sealing technology ensures outstanding cleaning performance and fully maintenance-free operation.
With a long service life of 2~3 years, the filter element delivers stable and reliable performance throughout its lifespan, a superiority unmatched by peers.
4. 304 stainless steel housing, upper & lower cover thickness: 1.8 mm (industry average: 1.2 mm), cylinder thickness: 1.45 mm (industry average: 1.0 mm), Hydrostatic test: over 400,000 cycles (national standard: 100,000 cycles)

5. ChengrongEra water purifiers are designed to compete with world leading brands, never cut corners, even on details invisible to customers.
To ensure the hygiene and safety of the stainless steel cylinder, we provide 100% full polishing on both inner and outer surfaces, while our peers skip this step. Every cylinder also undergoes 100% ultrasonic high-temperature cleaning, a process that our peers are not equipped to perform.
1. Intelligent Spin-Clean Whole-House UF Water Purifier, Performance Testing at Chengrong In-House Lab (Actual Shot)
Intelligent & Digital Control, a Milestone Spin-wash Technology, Unique in the Industry
Unlike traditional flawed designs where only water spins while the filter stays stationary, ChengrongEra auto spin-clean technology drives the filter itself to spin, achieving truly effective and thorough cleaning performance.
2. Auto Spin-Clean Technology, pioneered by Chengrong, Welcome global peers to benchmark against ChengrongEra
Our newly developed proprietary filter sealing technology guarantees thorough and effective cleaning, a standard unmatched by competitors.
The centrifugal force generated by forward and reverse spinning, throws off impurities attached to the membrane surface and trapped inside the tiny pores.
At the same time, the water filtration system automatically flushes water in and discharges waste simultaneously, quickly expelling all washed‑off contaminants from the filter housing.
3. Filter cartridge spins automatically on schedule, maintenance-free, no manual cleaning required, friendly to users, a Feature Unmatched by Peers
Users only need to set the spin-wash interval and duration according to water turbidity, keeping the PVDF membrane surface clean, the filtration pores unobstructed, and preventing clogging.
间隔单位按钮 (Cleaning Interval Unit Button)
Used to select the time unit for cleaning interval: hours (the left one) or days (the right one)
清洗间隔按钮 （Cleaning Interval Button）
Used to set the desired cleaning interval, for multiple cleans per day, set in hours；for cleans every few days, set in days.
Recommendation:
Muddy well water: auto spin‑clean once a day
Municipal tap water: auto spin‑clean once every 7 days
清洗时长按钮（Cleaning Duration Button）
The spin-cleaning duration can last up to 90 seconds, the more turbid the water, the longer the cleaning time.
You can adjust it according to actual cleaning results.
立即清洗按钮（Clean Now Button）
Press the Clean Now button twice in quick succession to start the automatic spin-clean function immediately.
4. Smart spin-clean design enables simpler plumbing connections and easier installation.
It greatly reduces the skill level required for installation, making it highly user-friendly and cost-effective.
Plumbers only need to connect four pipes:
raw water inlet pipe, filtered water outlet pipe, and waste drain pipe, an optional bypass pipe
No backwash piping is required, which greatly reduces the professional skill level required of plumbers for installing the water purifier.
For households without a water tower,
This whole-house UF water filtration system delivers instant filtered water that can support up to 2 faucets at the same time.
For households with a water tower,

Katerian bought ChengrongEra mineral-water-like water purifier, to eliminate bottled mineral water from the supermarket, to save money and also drink healthy.
She is a customer who really knows water inside out.
Before ChengrongEra water purifier, she had bought a RO water purifier for money saving and direct drinking. But just used for 3 months, she noticed a change in the flavor in her water, then she start to learn more knowleoge about the RO water purifer and the water.
The change of the water flavor is because the Bacteria in water exceed the standard limit.
Due to the ultra-high filtration precision of the RO (Reverse Osmosis) membrane, it not only intercepts suspended particles, bacteria, and viruses in water, but also removes beneficial minerals and trace elements. As a result, the produced water contains almost no minerals or trace elements, leading to a significantly reduced Total Dissolved Solids (TDS) value. However, such water has an extremely bland taste that is not pleasant to drink. To improve the taste, an activated carbon filter is usually installed after the RO membrane to enhance the water's flavor profile. Furthermore, activated carbon is inherently prone to bacterial growth, which in turn leads to excessive bacteria in the purified water, causing the water to develop an unpleasant flavor.
Katerian wanna have better healthier lifestly, but the RO water purifier would remove the beneficial minerals and trace elements, and with the risk of excessive bacteria. Thus, she wanna find a water purifier that can intercepts suspended particles, bacteria, viruses, and residual chlorine, but remain the minerals in water.
Then ChengrongEra water purifer comes to her eyes.
The main reason that Katerian decided to purchase ChengrongEra mineral-water-like water purifer is the word "mineral-water-like", and the Chengrong factory, she thought purchase from the factory could get more technical support.
After received the water purifier, everything is wonderful, the water taste very good, just like the mineral water in the supermarket.
