Prusa Advanced Filtration for CORE One / One+

The Advanced Filtration System is designed specifically for the Prusa CORE One and CORE One+ 3D printers. It includes a HEPA filter rated at 99.9% efficiency, an activated carbon filter, and a high pressure blower, all housed in a compact unit that mounts to the rear exhaust of the printer.

This filtration system targets both ultrafine particles (UFPs) and volatile organic compounds (VOCs), which are produced in higher concentrations when printing materials such as ASA, ABS, and other filaments that require elevated temperatures. The activated carbon layer also reduces odor during printing.

The system integrates directly with the CORE One's firmware, allowing automatic fan control without manual intervention. Filter replacement is straightforward, with an estimated HEPA filter lifespan of at least 600 print hours. Prusa developed this solution after extensive testing on their own print farm of over 600 machines. The filters were engineered in partnership with a company specializing in air filtration to ensure effective particle and odor reduction in 3D printing environments.
