When soldering, remember to use air filtration to remove flux fumes from the air.
See Amazon and eBay for reasonably priced air filters.
A noisy fan makes it much less likely that you will continue to use your air filter.
I replaced the noisy 120VAC fan in the unit below for the much quieter 12VDC computer fan.
A small booster fan gives you more distance between your work and the filter location.
If you do a lot of soldering, you might want to invest in a small HEPA room air purifier.
A small unit like the one shown is just right for a work bench.
Air Purifier is ~$90.00 and filters are ~$15.00 (6-8-month effectiveness), very quiet at low and medium speeds.
Almost no sound at speed setting 1, reasonable at setting 2.
Edit, see post #1066 also.
