Pure water machine: The main technology used is reverse osmosis membrane. The working principle of a pure water machine is to apply a certain pressure to water, allowing water molecules and ionic mineral elements to pass through the reverse osmosis membrane. However, the vast majority of inorganic salts (including heavy metals), organic matter, bacteria, viruses, etc. dissolved in water cannot pass through the reverse osmosis membrane, thus strictly separating the permeated pure water from the permeated concentrated water.

A water purifier is a water treatment equipment that deeply filters and purifies water quality according to the requirements for water use. The pure water machine we usually talk about is actually a type of water purifier, with the most precise and highest filtration degree, also known as the "terminal water purification equipment".
