Laser Air Filtration DIY [Home HVAC filters]

DIY filter box for outside air exhaust from a laser, using inexpensive household HVAC filters. Made out of scrap MDF and 3D-printed inlet/outlets. Uses Blower that came with "red and black" 60W laser, but provides some filtration so it's not pumping raw smoke out to the environment.

Update March 2021: Added activated carbon: https://www.youtube.com/watch?v=E1zXqY-Z0s0

*Not recommended without an exit to outside air. This is how I made my filter box, but I cannot vouch for its true effectiveness as it has not been thoroughly tested. If you choose to, use/build at your own risk.
