HEPA Filter Mount for 5015 Fan

This project combines a 5015 blower fan and a HEPA filter normally used with robot vacuums and mounts to 2020 extrusion.  The single fan version uses a filter that has been cut in half, and the double fan uses a whole filter.  The filter press-fits into the lid, and fastening the lid will hold the entire assembly in place.  The mount has a cutout on both sides for wires and connectors.  

In addition to several mounting options, I also included my Fusion360 file with many design elements parameterized, including filter size.  It uses separate bodies for all of the mounts so be sure to select the ones that you want when exporting the design.  

Supplies

For hardware, you will need: 

• (4) M3x5x4 heat set inserts in the base
• (4) M3x16 SHCS to mount the lid to the base
• (2) M3x8 SHCS to mount to 2020 extrusion
• (2) M3 nuts for the extrusion.

I modeled for this filter: https://www.amazon.com/Electropan-Filter-Replacement-Robotic-Cleaner/dp/B0782T7L6P/.  I also used some 5 mm x 1 mm foam tape to help seal the filter and reduce fan vibrations.  

Disclaimer

I am not willing to make any promises about air quality.  I am simply making the assumption that my filter is better than no filter at all.  I am also taking the filter manufacturer claims at face value.  As a vacuum filter, the manufacturer suggests replacing it every 2-3 months.
