The third stage: carbon rod activated carbon: further removal of chlorine, organic compounds, heterochromatic, odor, turbidity and the like.

The fourth stage: RO reverse osmosis membrane: 0.1 nm pore size , remove bacteria, viruses, heavy metals, and other organic impurities in water.

Level 5: Post-activated activated carbon: Adjust the pH of the effluent and improve the taste.

Water machine filter replacement:

1. The pure water machine filter mainly relies on the filter element. Generally , it needs to be replaced once every 6 months to 9 months. Of course, the specific time still needs to look at the raw water quality and water output. The yellowing of PP cotton indicates that the water quality is relatively poor ; if the amount of water used for a period of time is reduced, it means that it needs to be cleaned.

2 , pure water machine filter replacement needs to prepare these things: original filter, equipped with tools, mops and other tools and raw materials. First, turn off the power to ensure safety. Then use the small tool to remove the filter barrel. Note that there must be water in the dispenser, so prepare a mop.

3 , after removal, pay attention to a small washer, usually black. Replace the old filter and replace it with a new one. There is also a transparent gasket on the filter element, so don't get rid of it. If it doesn't, the effect will be much reduced. Place the gasket on the water outlet and install the filter. The new filter is rinsed with water and the filter cartridge is installed in place with a small tool. Finally, open the water inlet, turn on the power, and put water for one minute to two minutes to check for water leakage. If not, the water filter element will be installed.
