I bought a laser cutter and the stipulation was that I must have excellent fume control if I were to get one put in the warehouse. I didn't want to pay the crazy costs of a fume extractor. So, over the weekend I designed and cut this one instead. Here are all the parts necessary if anybody is interested in the costs. I chose very expensive filters - almost the most expensive I could find - and still came in way under the cost of a typical fume extractor:
(1) 8' x 4' X 1/4" Sheet Baltic Birch - $30
(1) 3-set medical grade air filters with pre-filter, activated carbon, and hyper hepa filter - $290

(1) 10lbs of Activated Carbon - $25

(1) 8 " Inline Fan - $80

(1) Wood Glue - $5
(1) Super Glue - $1
(1) 25' Duct - $30
(2) 8" Duct Starters - $8
(1) 8" x 4" Reducer - $8

So I'm ready to finish the assembly, but now I want to engrave something funny or cool on the door. Any good ideas?

Thanks for the post. I have seen a few of these before, but this one motivated me to finally order everything. I have been wondering what I was going to do this summer. Currently my rigs costs me about $8.50 a day in electricity, but saves me about $5 a day since it is literally heating my entire house.
@ .12 kwh the fan at full speed costs $.55 a day. I ordered a bigger tent and 2 of the fans. Hopefully I can run them at some lower percentage (they come with controllers).
This is what I ordered:
Get a grow tent , an inline fan and 8-inch flexible ducting . Put the fan in the uppermost part of the tent so it evacuates hot air, then stick the ducting so it blows out the window. Problem solved!
I’d go with this at the smallest

I have one size down for my 40w epilog and would like a bit more flow. Of course my run is not efficient so I will see how I feel after fixing that.
You can never have too much exhaust flow IMO
