osmosis filter
Carry out coarse filtration of the original
water, and filter out mud, sand, impurity,
iron rust and suspension, etc.
Filtration accuracy is nearest to 0.001
-0.0001um, only allowing the passage
of water molecules, and almost
completely retaining harmful substances
in water such as pesticide, bacteria,
virus, and heavy metal ions.
Further absorb micro-molecules organic
