Are Portwest Filters Reusable?

In short, yes they are. If left unopened, all Portwest filters have an approximate shelf-life of around five years. Once opened, shelf-life depends on a range of factors, including how much gas they've been exposed to, the condition of the material and how they're stored.

To prolong the life of your filters, it's recommended you remove them from the workplace when not in use and that you store them in an airtight container.
