With retirement approaching, I have only recently decided to start modifying guitar electronics after years of letting a tech do it for me. I'm also about to start on a partscaster build. Both of these will mean I'm going to be getting into soldering. My wife is unhappy with the fumes around me or even in the house. I was pretty sceptical but after a bit of research I quickly found that there was a potential health hazard with Rosin fumes. I also have a bit of a health issue which means I need to be a bit careful around chemicals ( proper coffee and ciggies are things of the past for me ) so I'm going to take precautions. So far I've considered the following ideas 1. I thought maybe opening a window and blowing a fan in the general direction of outside might do the trick. A bit hit and miss perhaps. 2. I also wondered if ( as we have plenty around these days ) if wearing a surgical mask might do the trick. The masks I use are disposable and are 3 ply. I would have thought that if these stop a virus they would stop particles from flux vapour. 3. Alternatively, once the weather gets warmer I would do it in the garage with the door open. 4. Last I thought I could buy a cheap filter like this https://www.amazon.co.uk/KOTTO-Abso...s=soldering+hepa+filter&qid=1611442539&sr=8-3 But then I look at the filter they supply and it seems ridiculous. I realise many people are unaffected by these but some are and my logic is why take the risk as I already have an issue, even though most people, would probably be fine. I have also heard of those who have suffered from relatively short exposures so I'm hoping to avoid unnecessary risk without going crazy about it. What would you were the merits of my various proposed methods above?
