Promethean FAQ

The Promethean air cleaner can be placed adjacent to the printer, inside an enclosure, or hooked up to an enclosure as a fume extractor using duct. The unit is versatile and comes with duct and adapters so you could accomplish any of these right away. While having it right next to the printer will work, using an enclosure is always more efficient in capturing particulates & VOCs plus it has the added benefit of keeping in heat that will help prevent prints from warping.

Yes, any air cleaner will not be able to capture all of the fumes generated from resin. Thus, it is highly recommended to place the priority on ventilation and use filtration as a secondary defense.

It is recommended to replace the MERV 13 filter every 2-3 months. The activated carbon should be replaced every 2-3 months. For high-demand applications, the carbon should be replaced upon the reemergence of odors as the lifetime is highly dependent on filament/resin/print settings/concentrations.
