<div>Cool,</div><div><br></div><div> Industrial safety recommendation; I know you are doing your best to route to the outside, but in the event the exhaust is going to contact the interior air of the building, I recommend that a charcoal filter be placed in the exhaust duct upstream of the exhaust fan to absorb any fumes before the air exits. </div>
<div><br></div><div>For commercial filters; they can usually go for as low as $25.00 a piece and require replacement after 3 months of service: <a href="http://tinyurl.com/6npk9yz">http://tinyurl.com/6npk9yz</a> (Search also 'charcoal air filters'). </div>

Eventually it'd be nice to have it go out through the roof or vent stack or wall or something. For now though, I'm just planning on routing it to the giant exhaust fan in the chemistry area to avoid having to deal with any facilities issues. Baby steps.<br>
<br>2. If I'm going to be taking donations to help fund this, then I plan on making this 'our' property. Unless we want to order it through ML256's amazon account for some kind of tax/ nonprofit perks reason, I was just planning on ordering it myself and donating it to the shop, so any money you want to chip in would count as a donation to ML256 if we do it right. I'm not sure of the exact logistics though. Might be easiest to have the shop reimburse me, and then we all make "unrelated" donations for our pledge amounts. Or something. Taxes are hard...<br>

I imagine you plan to attach to the building's vent stack?<br>

I definitely want to help fund this. What is this metaphorical hat I'll be<br>
dumping money into? That is, would I be donating to Makers or to you<br>
personally?<br>
