About this item
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. Dual-action cleaning (backwashing + manual washing), exclusively innovated by Chengrong factory, rarely found elsewhere in the industry, solveing the fouling and clogging issues caused by high-precision filtration, our peers cannot do it.
Chengrong-innovative dual‑clamp structure design, allows users to easily perform backwashing and manual washing of the filter cartridge at the same time, not only cleaning the filter surface thoroughly, but also removing impurities blocked in the 0.1μm filtration pores, 99% of competitors can only clean the surface.
This design thoroughly solves the fouling and clogging issues caused by high-precision filtration, ensuring more stable water flow and a longer service life of the filter cartridge.
3. ChengrongEra UF filter cartridge is tested by SGS and complies with NSF 58-2023 standards, with a 5-year filter lifespan plus a 5-year warranty, a level of quality and reliability you won’t find anywhere else.

Model Selection Guide for Whole-House Water Purifiers
The selection of whole-house water purifier models should mainly based on membrane flux, not outlet flow rate. This is different from most competitors, yet it is a more scientific and accurate method.
Membrane flux selection depends on daily water consumption.
As a professional ultrafiltration manufacturer with 18 years of practical experience, Chengrong has summarized two formulas to help customers choose the appropriate membrane flux based on household water usage.
1. With Water Tower
Daily water consumption: 200L per person per day
Formula: Required Membrane Flux > Number of People × 200L/day × 5
Example: 5-person household with water tower
Required Membrane Flux > 5 × 200 × 5 = 5000L, Recommended model: 168-4000A
2. Without Water Tower
Flow rate per tap: 300L/h
Formula: Required Membrane Flux > Number of Taps × 300L/h × 5
Example: 5 taps without water tower
Required Membrane Flux > 5 × 300 × 5 = 7500LRecommended model: 168-4000A

What Our Customers Say
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.
