Glowforge Air Filter Cartridge Lifespan


There are a lot of factors that go into the lifespan of an air filter cartridge. Some of those include how often you print, the designs you print, cutting versus engraving, and whether you follow the directions in the user manual for proper operation. For that reason, it is difficult to predict how long an air filter cartridge will last.

To estimate, we tested Proofgrade materials with a standard Glowforge test print in a Glowforge Pro using a Glowforge Air Filter. The test print simulates an average Glowforge 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.
