The useful lifespan of an air Filter cartridge depends on numerous factors. How often you print, the material you use, and whether you mostly cut or engrave can all affect cartridge life. (As can following the user manual's instructions.) Light users may only need to change filters once a year, while more frequent users might require monthly replacements. Acrylic typically fills the filter very slowly. Hardwoods aren't very taxing but plywood might be, depending on the glue.
To estimate average lifespan, we tested Proofgrade materials with a standard Glowforge test print in a Glowforge Pro using a Glowforge Performance Filter. The test print simulates an average print; it’s 11 minutes long and is a mix of cutting and engraving that reflects typical usage.
If used only for cutting, cartridge life may be roughly half as long. If used only for engraving, it may be more than twice as long.
Note that we have only tested, and can only recommend, Proofgrade materials. Materials from other sources may work just as well, but some materials may clog the cartridge almost immediately. For example, MDF products (including Proofgrade Draftboard) will dramatically lower your filter cartridge life.
