The second-generation filter element landed heavily, with four guarantees

Old generation filter element structure: No. 1 filter element adopts melt blown PP cotton, No. 2 / 4 filter element adopts granular activated carbon, and No. 3 filter element adopts RO reverse osmosis

Comprehensive upgrade of second generation filter element

No. 1 filter element: for PP cotton, the optimized scheme uses folded PP instead of melt blown pp. after testing, the optimized scheme significantly improves the flow rate / turbidity removal rate / water flow

No. 2 filter element: for pre granular activated carbon, carbon rod is used to replace carbon particles in the optimization scheme. The flow rate / total water flow in the optimization scheme is significantly improved, with less black water and obvious ro protection effect

No. 3 filter element: further verify the reliability for RO membrane

No. 4 filter element: for post granular activated carbon, the optimization scheme uses carbon rod to replace carbon particles. The optimization scheme has significantly improved flow rate / total water flow, less black water and good user experience.
