There is always some residual smoke left in the unit that escapes after lifting the lid. But just for FYI… I would bet 3 out of 4 folks thought they had a tight fitting vent. Then they run the GF and find there is a strong smell caused by incredibly small leaks where the vent hose meets the GF unit or where the vent hose connects to a window or external vent. Needs foil tape to seal good.
I have a two foot shot straight out the wall. Used foil tape on the flex tube end points. No smells.
A small wisp now and again after a cut if I am in too big a hurry, but the Wife has not complained and she can smell a cat farting in the next yard, so…
Most of the smell winds up deposited on the masking too…remove that as soon as the job is done and stick it in a ziploc bag. Cuts way down on the smell.
Great, thank you! I saw that you said two-pack, but the description says one, so I ordered two and will just return one if necessary. Gotta love free dropoffs for Amazon returns!
One thing to check is your window…I taped and retaped and used booster fans and was STILL getting a lot of smell in my shop.
One day I finally noticed that my nifty window insert (similar to yours) resulted in a large gap between the two window sections…I guess windows aren’t designed to be left half open. So I was venting it out, and that gap between the two panes let the smell right back in.
So I added some weather stripping between the two window sections…and the smell is finally gone!
Of course, there is a gap, just as you had said. And of course, the weatherstripping I have on-hand is not the right kind, so I need to find something else at the hardware store tomorrow. I need something that’s lower density so it doesn’t get torn off when I slide the window.
I picked up something from the hardware store that does a wonderful job of sealing the window, yet the smell persists. I guess I will have to wait for those attachments to lengthen the hose contact and then tape all of that off. Foobot says the air quality in my office is bad. I have my Molekule air filtration running in the desperate hope that it will help, but it doesn’t seem like it. My office smells like smoke everywhere!
Ran into exactly this last spring with my PRU. In my case, it turned out the weatherstripping itself was not gas/odor/smoke proof, being made to just keep rain and dust out. I backed it up with weatherstripping tape and boy howdy did that make a huge difference!
Still waiting on adapters, but in the meantime, check out this really nicely-designed duct fan I picked up from amazon!!! I think this will help keep air flowing through my office during cutting.
