    When dealing with a neurotoxin such as lead, probably isn't good enough in my book. As I said, the potential presence of lead from soldier should be assessed by a certified industrial hygienist. And the temperature is high enough to melt the lead. There have to be some fumes produced from it. I'm not familiar with any adverse effects from flux, but it's possible. I would assume that it's an organic, therefore particle filtration would not be very efficient. Ventilation issues could be thoroughly assessed by a certified industrial hygienist.

    There are experts in the field of engineering known as industrial hygienists. I'm a position. I know that led is bad, and doesn't only affect those directly working with it. People take it home with them. People around the person producing lead fumes will inhale it. It's especially bad with pregnant women and children. Especially pregnant women who do not yet know that they are pregnant which is potentially every College female.If you are working with lead, someone at the University will be able to assess the situation and determine if there is a true Hazard to students. Using a hood like they use in chemistry Labs would decrease the exposure in the room , but may not be sufficient under OSHA regulations. Substituting a non lead solder takes care of the problem.

I'm just afraid that using a filter of the type that you made we'll take this other smell out of the air, the organic component which is afsorbed by carbon filter, but will only spread the fumes (metal fumes) around the building.So to sum up, I'm not an expert in ventilation or filtration but industrial hygienist are. You are right to suspect that soldering may present a health hazard, if it contains LEAD. An industrial hygienist could help with your problem, as it is not unique to your lab. Lead is too serious to MacGyver a solution.

    My voice recognition failed me. It should have typed electronic solder doesn't contain lead anymore. If you are soldering with lead-based solder, you need a professional filtration device, or something at least to remove the metal fumes from your work space. Like a hood, but I don't believe you're allowed to vent led directly into the air.If you work with lead soldier on a regular basis, you should be familiar with it. You should wash your hands after handling it. Should do it in an area where children don't have access because they are way more susceptible to lead toxicity. And the fumes will settle on surfaces.Lastly, why not get a good fitting niosh approved respirator that is rated N-99. Far more convenient and probably more effective for this

    Duvall, Electronics other doesn't contain lead anymore. It's silver based.And I have taken a graduate-level course in industrial hygiene which covers filtration and air sampling. You would have to know the size of the particles being generated by the soldering iron to know what size filter would be appropriate. Given the small size, you would need a very small pool filter which would require quite a bit of suction power. Not sure this would even do the job. It likely just distribute the metal fumes throughout the room so you don't see it

    8 Pool Noodle Life Hacks & Diy's

    Consider using pipe insulation for some of the uses being touted here. It's not that expensive. And it looks a lot better than a brightly colored kids to work.

    Or you could spend $20 and make a headboard for your bed. I mean... Really... Come on . LOL.

    Another winner of a Darwin Award. Those noodles aren't heat resistant. So when your Jeep burns up... Your insurance won't pay for it because you made a modification to it that caused the fire.And yes Virginia... There is heat resistant foam for this kind of application. Stop being so cheap

    Additional R-value? You realize the top of the can is not covered, and open to the air... Right? And when it's on the table, the air is still trapped, providing some insulation. Unbelievable. People watch Mythbusters and think they're scientists
