Another variation on adding filtration to the Creality K1. This one includes HEPA (for particulates) and activated charcoal (for VOC, volatile organic compounds) in one snap-on assembly requiring no modification of any sort to the K1.
Some acknowledgements:
- Basic model based on my previous activated charcoal-only filter: https://www.printables.com/model/536521-k1-expanded-filter
- Although I might like a higher static pressure fan the OEM fan does seem to push a good amount of air through the filter stack.
- Given the size of the HEPA filter my new design has less surface area than I would like (the basis for the “expanded” filter).
- Addition of HEPA filter influenced by: https://www.printables.com/model/599721-creality-k1-hepa-filter-housing
- As noted in the reference filter it might be better to “suck” by moving the fan to the back, but given the space required and the ease of using my approach I think my new design is a good tradeoff.
- Note that my design does not have an actual seal, something I might think about adding in the future. But it's not bad.

- My design fits two layers of the referenced cut-to-size material.
