Antarctic people. Antarctic water purifier is a kind of gradually tightening water purifier. Its internal pipeline is designed as a loose filter element at the front and a tight filter element at the back. It consists of PP melt-blown filter element, granular carbon, compressed carbon, RO reverse osmosis membrane or ultrafiltration membrane, and post-activated carbon. Usually, these five stages are connected end to end. Trapped and deposited in the filter element, it needs to be disassembled and cleaned manually regularly to ensure the normal operation of the machine.
