Granular activated carbon (GAC) filter in the Big Blue size. The loose granular carbon gives high flow with low pressure drop, making it a good chlorine-reduction stage for high-flow pure water and RO systems.
- Size: 4.5" x 20" (Big Blue)
- Media: granular activated carbon
- Fits: standard 20" Big Blue housings
- Removes: chlorine, taste, odour and organic contaminants
Tip: pair it with a sediment or carbon block filter for full pre-treatment ahead of the RO membrane.
