If you’re soldering a lot, I highly recommend getting something that eliminates the smoke. Depending on what you’re solderinging, the smoke varies from “bad for you” to
“makes you glow in the dark”. As far as I know, this comes down to two possible choices:
Fans with filters
I don’t know that much about this one, because I decided to go with the bugee option below.
Fans with filters in boxes
This sucks up the fumes, has great filters and is easy to hide behind your desk, but it’s pretty expensive for what is essentially a weak vacuum.
