My desk is 48" away from my ValueJet. I was really getting a lot of fumes...and I was feeling a little too good while I worked...(great for designing wild stuff though).
Anyways. I installed dual range hoods I bought at Home Depot and vented them outside. They work GREAT. Cant smell a thing when they're on. Forget to turn them on and it's a quick trip to my happy place. lol A pretty cool setup if I do say so myself!
