Affordable DIY Fume Laser Fume Extractor that actually WORKS!

Commercial Fume Extractors are super expensive! DIY Fume Extractors are hit and miss. This one actually works! What's the secret? It uses commercial BOFA filters. That makes it a little expensive to operate, as filters alone are just under $450. However this is first fume extractor I had that eliminated all laser cutting odors in my basement. See how I made it and you can too.

Update: I recently added a 6" charcoal hydroponics filter (like this one: https://amzn.to/3EzWC86) after last fan and it COMPLETELY eliminates all orders! What's even better that filter is cheap, and it lasts and lasts and lasts because it has to filter tiny bit of fumes. I never vent outside anymore!

I want to give credit and huge thanks to Brandegee Pierce (   • DIY Meets High End Fume Extractor for...  ) as it was mostly his idea, and I just built upon it.
