I bought this benchtop tool about 2 months ago because I was tired of solder smoke going straight into my face while soldering. It seems the best position for seeing what you're soldering is always directly over the joint, especially when using a microscope.The weller WSA350 works well to suck the fumes and smoke away, and the filter is an added plus. Just a note, if you are reworking a conformally coated printed circuit board, don't expect this simple fan & filter to protect you and those around you from the toxic gases emitted if you're using heat to remove the coating (never a good idea for a multitude of reasons). All things considered this is an relatively inexpensive but effective bench top accesory. The only minus is it doesn't have a variable speed control and is pretty noisy running at full tilt.Although I bought a set of filters for the fan, you don't need to as mine came with 3 filters included.Weller WSA350 120v Bench Top Smoke Absorber
