1st stage: Pre-filter P.P 5 micron.
~ This pre-filter filter out dirt, rust, and purity.
2nd stage: Lose carbon filter
~ Remove chemical such as odors, chlorine, and chemical fertilizer.
~ Protects RO membrane.
3rd stage: P.P filter 1 micron
~ Filter fine particles and harmful pollutants.
~ Protect and increase the efficiency of RO membrane.
4th stage: RO membrane 0.0001 micron (0.001 micron only)
~ Advanced membrane technology separate and drain out impurities such as bacterial, virus, lime, heavy metal, pesticide, and chemical and produce clean and pure water.
5th stage: Activated Carbon Filter
~removing organic material and resistance anti-bacteria from water and have super antioxidant ORP of up to -250mV. Antioxidant Mineral can abundance of negative ions for reducing oxidation at human body, prevent free radicals, antioxidant thus anti aging & anti tiring also. Furthermore with small water molecule clusters and thus is more easily absorbed into our body. Recommend replacement 3 years or within 20,000 liters whichever come first
