The filtration system consists of three main filters:
- PAC (Pre-Activated Carbon) Filter: A 2-in-1 pre-filter that removes larger particles like sand and rust, as well as chlorine and odors.
- RO (Reverse Osmosis) Membrane Filter: Contains ultra-fine pores to retain the smallest contaminants in the water.
- CF (Carbon Block) Post-Filter: A 2-in-1 post-filter that refines the water with valuable minerals (calcium, magnesium, sodium, potassium) and balances the pH value for a fresh taste.
