Ensure your OsmoFresh Nasco always delivers fresh, neutral-tasting water with the original activated carbon block filter. The block filter effectively binds chlorine, odors, tastes, and many organic residues – for pure water with every glass. Its primary purpose is to protect the osmosis membrane. It should be replaced every 6-12 months.
| Supplement | Benefit | Link |
|---|---|---|
| Basion Vitalization Cartridge | Enriches osmosis water with minerals, leading to more alkaline water | Basion |
| Reverse Osmosis Membrane 180 GPD | Removes finest residues (<0.0001 µm) – for maximum purity | Membrane |
Membrane Replacement: The 180 GPD reverse osmosis membrane should be replaced every 2 years to avoid performance degradation. Or earlier, if the values are no longer good.
Note Bayonet Fitting: Some OsmoFresh Nasco systems use an activated carbon block with a bayonet fitting (see product photos).
