HRV for fumes
I saw a suggestion elsewhere which seemed to make a little sense, and I wanted to run it by folks more knowledgeable about HRVs. The idea is to use an HRV to vent solder fumes to the outdoors.
I work with solder, which produces some fairly nasty fumes. Contrary to popular belief, the issue is not lead, but the smoke from the flux. The standard solution is a filter with an intake right next to your iron. Home solderers often use chintzy filters that amount to a computer fan and a flimsy charcoal filter. They do little better than diluting the smoke before you breath it. More expensive units are like miniature vacuums with a HEPA filter and a heavy load of activated carbon. They’re quite effective, but the filters are extraordinarily expensive, and they draw up to 100W at full speed.
A super small HRV seems to make some sense. You get the fumes out of your workspace, and you don’t waste a ton of energy doing it. My two concerns are the long term effect of small quantities of mildly corrosive fumes on the core, and upfront cost.
I was also thinking that an exhaust fan, like in a bathroom, might be a better solution. It might be on for longer periods than a bathroom fan, but the air flow can be lower, since it will be ducted directly to the fume source. So, the energy penalty for running it might not be terrible.
I don’t have any specific question, but I’m curious about your thoughts?
