The fan is fairly quiet, sturdy and well build. Its cute. I cant think of what this would actually be effective for, but it isnt effective for soldering with lead. Two inches is NOT a large distance. I had to set this fan on top of the piece I was soldering to get it close enough to absorb the smoke. I can see right through the carbon filter. I doubt it actually absorbed anything, but only a blood test will tell. What I have learned so far: the most expensive filters can filter particles down to .1 microns. Lead, smoke, viruses and mold spores can be about that size, maybe smaller for all I know. Given the price point and my astute observation skills (aka holding the filter up to the light and looking through the gaping holes) I am really doubtful that this carbon filter can absorb anything even 10x bigger. After some careful and lengthy research, Ill build my own. If youre soldering with lead or other heavy metals, do your research. Protect yourself.
