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.

Key indicators

• 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.
