No window? No problem! Don’t let ventilation issues stop you from placing your Glowforge where you want. The Glowforge Air Filter sits on the ground near your Glowforge printer to clean the air in your home, classroom, or office space. Simply attach the filter to the hose on your printer to filter out particles and distribute clean air to the room. With its compact design, you can also store the filter under a desk or table with ease.
