this type of water purifier has adopt reverse osmosis type purifier system which including the following five stages:

Stage 1: Precise PP Cotton Filter:
this stage will remove some impurity in water, such as suspended solids, silt, sand worm, rust and etc. the core of filter is dense and uniform, which can ensure the speed of water flow and reach maximum filtering effect.

Stage 2: Granular Activated Carbon Filter (GAC Filter):
this stage will absorb some impurity in water, such as peculiar smell and color, residual chlorine, humus and etc. Micro pores account for 90% of all the space, which can greatly enhance the absorb capacity of activated carbon.

Stage 3: Compressed Activated Carbon Filter:
this stage will remove some granular substance in water.

Stage 4: RO Reverse Osmosis Membrane:
the pore diameter of membrane is about 0.0001 micron, which means a bacteria can be through only after 4000 times reduced.

Stage 5:Post Purified Activated Carbon Filter:
this stage can greatly improve the taste of water.
