  1. Pre-filter – The primary filter which separates the big sediments from the water before entering into a RO system. Thus it reduces the load of the internal filters and increases the life of the RO system. 
  1. Sediment filter – Filters microscopic particles 15 times smaller than a grain of sand.
  1. Pre-carbon filter – remove elements that cause unpleasant taste and smell to the water.
  1. RO membrane – Reverse osmosis membrane is a thin membrane that does not allow dissolved substances such as radium, lead, and arsenic through it.
  1. Post filter – Removes any possible residual taste from the tank.
  1. Min-Technology – adds essential minerals to the water and maintains the accurate pH value of water.
