I made this to help with the smell when printing with Asa, abs, etc. I do not have anything to measure air quality coming out after placing this. It takes a Robotic Vacuum cleaner HEPA 40mm X 81MM X  14MM. If you make this and you have the equipment to measure air quality please let me know your results.

Printed with ABS, 100% infill to make the part a little stronger. Everything else is standard settings.
