It is all to easy to get wrapped up in the project you are soldering and accidently breath in a lung full of solder smoke. The smoke is very bad for your lungs, especially with lead-free solder. Do yourself a favor and get a smoke absorber. Small price for health.
Breathe easy with the Hakko FA-400 bench top smoke absorber. The FA-400 removes soldering smoke and fumes quickly, safely and efficiently. The unit can be used in a vertical (standing up) position or low-profile position (laying down.) When used in the low-profile (laying down) position, efficiency and air flow is increased by approximately 2.6 times.
