The Bunn 3L Lever Action Airpot is an office space workhorse with action packed features! Is it bullet-proof, you ask? We haven't tested it, but we'd like to think so. Some have gone as far as to call it "unbreakable" (seriously), but someone also said that about the Titanic so maybe take that with a grain of salt. Whether it would hold its own against an iceberg - we may never know. But we can verify that it is durable, insulated, and compatible with virtually all commercial airpot brewers. Its brew-through stem will save you the messy step of transferring brewed coffee from one vessel to another, because you can brew directly into this Lever Action Airpot. Capable of holding three liters of consistently hot coffee for hours on end, this Bunn 3L Lever Action Airpot will keep you caffeinated and ready to face any obstacle you might unearth throughout the day.
