Contaminants removed via physical filtration
Large suspended particles: Using filter media such as PP cotton and micron-grade non-woven fabric, these filters physically trap visible impurities-such as sediment, rust, insect eggs, and colloids-preventing them from clogging pores or scratching sensitive skin.
Fine sediment particles: High-precision secondary filtration layers capture tiny debris from aging pipes and limescale crystals, reducing the likelihood of showerhead nozzle clogs.
Residual chlorine and odor-causing contaminants
Free residual chlorine: Utilizing core filter media like ACF (Activated Carbon Fiber) and high-concentration Vitamin C gel-through physical adsorption or chemical neutralization-most qualified products achieve a residual chlorine removal rate of over 90%, with top-tier models consistently reaching around 99%, effectively eliminating the "bleach" smell of tap water.
Discoloration and odor-causing substances: The rich microporous structure of activated carbon adsorbs musty or putrid odors caused by secondary pipe contamination, as well as slight yellowish-brown discoloration, restoring the water to a clear, transparent state.
Harmful trace contaminants
Certain heavy metal ions: Mid-to-high-end models equipped with KDF alloys and ion-exchange resins can selectively remove heavy metals like lead and cadmium, reducing potential damage to the scalp and skin caused by long-term exposure.
Volatile organic contaminants: High-quality activated carbon layers adsorb disinfection by-products-such as trihalomethanes-formed by the reaction between residual chlorine and organic matter, preventing these substances from being inhaled via water vapor during hot showers.
