Filter Description

STEP 4

Post-Carbon

Post-Carbon filter removes VOCs and dissolved odors to improve the water taste, and a felt layer prevents carbon dust from flowing into the tank.

STEP 1 + 2

Pre-Carbon (Sediment + Pre-carbon)

Pre-Carbon filter eliminates dissolved pollutants
such as rust, chlorine, dioxane, VOCs, THMs, etc.

STEP 3

RO Membrane

Reverse Osmosis membrane filter with 0.0001μm pores effectively removes contaminants such as heavy metals, harmful ionic substances, E.coli, etc

STEP 5

SS UV Sterilizer

Kills 99.99% of microbes

Hardness

Reduction

MicroFilter's advanced ion exchange resin, with an impressive capacity ranging from 4.2 to 4.6 eq/L, effectively reduces hardness substances such as calcium and magnesium. This effectively prevents scale buildup and equipment corrosion. Our unique ion exchange resin, blending Na-form and H-form, contributes to sustaining the optimal pH levels for drinking water.

Chlorine

Reduction(Taste and Odor)

MicroFilter's Carbon Block incorporates premium coconut-based activated carbons featuring a specific surface area exceeding 1,100 m%/g. This ensures outstanding adsorption capabilities for effectively reducing dissolved residual chlorine and disinfection by-products in water. Through the optimization of activated carbon content within the carbon block, we guarantee a consistent water taste from the beginning to the end of its service life.
