content: I'm about to buy a solder fume extractor and for the model I'm looking at there is a ESD safe variant that costs about 10% more. My question is, is it really necessary? The fume extractor intake floats above or near the solder action and doesn't come in direct contact with it. I'll be honest and state that I'll probably buy the ESD safe version because just in case, but I still like to know if it is hocuspocus.

content: Do you understand/appreciate the level of surface charge that can develop on an insulator (think plastic housing) with an air flow over it? Ponder that for a bit and you’ve answered your own question. Unless of course having something within touchable range with charge floating all over it doesn’t matter to you.

content: Doesn't matter for any kind of hobby use case.What are the products you are looking at specifically? Usually its 50% more for the "ESD safe" version.

content: Whether this is necessary is your decision—but it’s not hocus-pocus, either.It’s well known that insulators can accumulate significant charge due to airflow. That extra 10% might be wasted if you’re a hobbyist working on gadgets that only need to function for a short period. But it may be essential if you’re a company handling electronics for safety-critical applications that must meet specified performance for 10+ years—and/or if your customer contract requires ESD-safe handling per a standard that could be audited regularly.There are also items like ESD-safe trash cans. Even in professional settings they can be a waste of money if they sit under your desk and no sensitive device ever comes near them.Ultimately, this comes down to your own risk analysis.If I go with my gut, I’d probably opt for the extra 10% here—even for hobby use—because airflow-induced charges can get nasty (especially in dry air), and the extractor may get quite close to sensitive devices. And an extra 10% really isn’t that steep; the ‘ESD premium’ is often much higher.

content: Even ignoring ESD itself, ESD-safe products tend to not attract as much dust, since they don’t build up a static charge. This makes them easier to clean. I’d pay 10% extra for that…

content: For hobby or non-certified repair or prototype workshop use you don't *NEED* a fully ESD safe extraction system. However due to the high risk of static buildup and discharge to nearby objects, I would recommend a bare ground wire through the duct, and an ESD safe nozzle at the intake.
