# How long is the expected lifespan of the replacement components?

CO₂ cartridges have a service life of 5 years, and water activators of 4 years.  
Both components must be replaced no later than the end of their respective service lives – or earlier in the event of corrosion, damage, or deployment. They are low-cost consumables and can be easily replaced.
