About cleaning filter:
1. First stage: PPF
PPF is the pretreatment filter of domestic purifier equipment. It is the first step to purify the raw water which can filtrate the sand, clay, rust and the floating substance.
2. Second stage: UDF
Activated carbon filter has the high adsorptivity which can remove the residual chloride, the color, the smell and organic substance.
3. Third stage: CTO filter
CTO can adsorb the heavy metal ion of the water. It is a further treatment function for the UDF stage, which can remove the residual chloride, the color, the smell and organic substance further.
4. Fourth stage: RO membrane
The aperture of reverse osmosis membrane is 0.0001um. It can through remove the bacterial, virus, heavy metal and organic substance in the water further.
5. Fifth stage: T33
T33 can remove the smell further, increase oxygen content and inhibit bacterial growth.
6. Six stage: Mineral stone filter
Turning regular water into fresh mineral water by absorbing and dissoving a number of harmful material such as heavy metals and vacterial. These stone which are taken from the bottom of the sea at depths ranging from 300 to 500 meters, change regular water alkali-type water through an ion-changing reaction.
Replace the filter regularly to maintain pure and clean water.
