Also need power (except Jinliyuan sample).
In contrast, does not produce waste water purifier, no power, water volume; filtration accuracy, but not as pure water, is relatively weak effect of inorganic salts filtered substance, only a clean water outlet.
The current mainstream water purifiers on the market there are two categories, one is the use of reverse osmosis (RO) water purifiers technology (commonly known as water machine, above all the use of this name), high filtration precision another is the use of activated carbon particles of impurities, ultrafiltration, microfiltration and other art water purifier (water purification, above all the use of this name), the water can be removed;, to remove most of the impurities and harmful chemicals in water , bacteria, colloids, organic molecules and other substances.
