The short answer
Unused cigarette filters do not really "expire" like food. Sealed plastic filters can be stored for a long time. What matters is keeping them clean, dry and sealed - moisture and dirt are what ruin them, not age.
What actually degrades a filter
- Moisture - damp filters clog and lose draw.
- Dust and dirt - an open bag collects debris.
- Crushing - deformed filters no longer fit snugly.
How to store cigarette filters
- Keep them in a resealable container or the original zip pack.
- Store somewhere dry, away from heat and humidity.
- Bulk buyers: a sealed tub keeps a large supply fresh - see the bulk filter guide.
So can you buy in bulk safely?
Yes. Because filters keep well when sealed and dry, buying in bulk is the cheapest option for regular smokers with no real downside on shelf life.
