4-Stage All-in-one Filter Cartridge: 

More Filter Materials, Higher Flow Rate

The filter cartridge combines 4 premium filter materials into one compact unit: 

Chengrong factory's groundbreaking design, different with all the peers, the filter cartridge is composed of folded cotton, activated carbon fiber (ACF), PP cotton, and our exclusive Chengrong-patented chloramine-removing ultrafiltration membrane. 

Clean and also Healthy for drinking: 

Using filtration tech inspired by mineral water processing, it locks in 99.99% of harmful contaminants (particulates, bacteria, viruses, residual chlorine) while preserving beneficial natural minerals and trace elements. 

This is the key difference from RO reverse osmosis water purifiers, our purified water is not only clean for direct drinking, but also healthy than the pure water produced by RO water purifier
