5-stage filter set

Description of 5-stage water filter set (Vietnamese or Taiwanese): First stage: Cotton candle made of polyethylene material that filters up to 5 microns and removes solid materials such as sand and clay. Second stage: Activated carbon stage helps remove unwanted materials such as chlorine and dissolved gases. Third stage: Solid carbon stage's function is to remove remaining impurities before entering the salt treatment stage.
