[sdiy] Fume extraction

[Roman Sowa]

IMHO anything that is just a fan and thin layer of whatever, is just 
making you believe it's working, but it's lying. It only takes out the 
big, visible particles. All the bad stuff is still circulating in the room.
For many years I have simply sucked it all outside, using complex setup 
of intake box with fans, pipe duct and final sucking fan straight to one 
of the ventilation inlets in the room. With filters on the way too, to 
at least stop some of it. But obviously it's not efficient to work like 
that during winter, because it pumps a lot of warm air outside.
Then I bought big fume extractor from Quick and I'm good. It has like 
40cm thick filter of various kinds. Adjustable speed, while the lowest 
setting seems enough.

It's even more important to add another hose connected to fume extractor 
over your iron stand, because most of the fumes in the room come from 
soldering iron tip nicely sitting on the stand, generating soldering 
fumes like it's 1970.
