I’ve been using mine for about a month: hours a day (pyrography/wood burning) and it works like a champ! I saw a YouTube video comparing this to a more expensive “known brand” and this one was the clear winner in my opinion for cleaning the air. The YouTuber was testing it while soldering with a handheld air quality mete. The Kotto kept the air quality at the lowest, safest level while the known brand (when used as directed) surprisingly very quickly hit the dangerous level and stayed there. It was only when the YouTuber turned the known brand into a different position (not recommended in the user guide btw) that the level dropped, although never as low as the kotto. That sold me. But the testing also revealed that the Kotto was slightly quieter and had a stronger suction at the same distance. I’ve seen other reviewers say they don’t like it because you have to keep the Kotto so close to your work, and yes, I do too, but I also figured that would be the case given size of the fan and the price point. Super, super happy with this fan and highly recommend it!
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.
Don't breathe fumes, that stuff is, literally, toxic. I recognized this design from working at an electronics company, so I was thrilled to have a chance to review it. The thing works as advertised, comes with several filters, and realistically makes the least amount of noise a fan can. The most important thing it does is draw the fumes from away from going straight up into your face. I can't believe the charcoal filters can remove all of the smoke, but the air does come out the other end transparent. Couldn't be happier :)
I make nail polish and my apartment isnt very well ventilated, even with the patio door open, so I was getting headaches and sore throat from the polish base fumes. Some of the pigments and fine glitters I work with also fly into the air when I open the bag or when Im mixing, which can get on the table, my glasses, or in my lungs! It sucks the little stray particles of pigment and glitter right up, and helps immensely with getting rid of most of the smell when Im mixing. I do have to work pretty closely to it which makes the polish a little on the cold side which is can cause clumping, but its worth it. Quiet too!
Works very well to keep work area free of solder fumes. Beefy construction, stays in place - not easily bumped from placement area.
