So I ended up getting this guy
https://www.amazon.com/gp/product/B00OZZZ7JU/?tag=ihco-20... Fits nicely under my welding helmet (which is main reason I got it) and is quite comfortable to wear.
Originally I had purchased in preparation for my paint job that I did at the end of September (moved from August). One weekend I ran out of gas while welding so decided to switch to the flux core I had. Man was that a bad idea, not having a mask on while welding flux in a low ventilated area is a big no no. Couldn't figure out the next day why I felt like I got hit by a truck, lasted a couple more days then as I was thinking back on what I had done this was the only thing that was different. Didn't feel like I was getting sick either, just felt like I got slammed in the chest with a sledgehammer and sat on by an elephant for a few hours. Remember watching a video by ChuckE2009 on youtube about his welding ventilation system and why he did that after having welded for a while without one and how bad it was for you to inhale the fumes (he was specifically talking about welding galvanized pipe) and the effects he felt afterwards, which were almost exactly like what I felt.
Now I wear the damn thing whenever I am doing anything grinding, welding or spraying related.
