Shelf life: durable device and filter element component
- Product efficacy does not drop below acceptable thresholds during storage.
- The integrity of product packaging is maintained during storage.
- 2 years (threshold acceptability).
- 5 years (most desirable).
- Threshold efficacy: see microbiological efficacy and turbidity reduction guidelines.
- Threshold storage temperature range: 4°C to 50°C.
- Most desirable storage temperature range: -7°C to 60°C.
