Mineral-retaining Under Sink Water Filter, Clean&Healthy Drinking Water
Chlorine-removing Ultrafiltration Membrane, a Proprietary Technology of Chengrong Factory, Even global top-tier brands can't remove residual chlorine from water
A complete home water treatment system typically consists of two complementary components:
Point-of-Entry (POE) -- Whole-House Ultrafiltration Water Filtration System: Installed at the main water inlet, serving as the first line of defense for all water used throughout the home.
Point-of-Use (POU) -- Under-Sink Water Purifier: Usually installed under the kitchen sink to provide clean, drinkable water directly from the tap.
Whole-House Water Filtration System acts as the first line of defense for your home's water supply.
It effectively removes sediment, rust, colloids, and other particulate impurities from the raw water, transforming turbid or muddy water into visibly cleaner, crystal-clear water throughout your home.
This prevents the buildup of contaminants in your househole plumbing, which can cause secondary pollution, bacterial growth, and accelerated pipe corrosion. It also extends the lifespan of water-using appliances, and keeps white laundry from yellowing, and prevents showerheads from clogging.
The filter membranes in UF pre-filters are primarily made of two materials:
PVDF Membrane with Support Layer: Also known as an outside-in membrane, which is callede microfiltration (MF) membrane, with a filtration precision of 0.1 μm.
PVC Ultrafiltration Membrane: Also known as an inside-out membrane, which is the true ultrafiltration (UF) membrane, boasting a high filtration precision of 0.01 μm.
