Good project. I think the problem is that people are thinking "It's just a couple of cuts, I don't need a mask or to turn on the DC just for that." The problem is the ultra fine dust that goes very deep in the lungs and doesn't come out. I am having breathing problems not caused by sawdust, but it sure as heck hasn't helped. Last month I have a bronchoscopy where the push a probe into your lungs and take picures and samples. Taking two antibiotics now, and they washed out my lungs during that procedure, which helped briefly. If you've ever smoked for any length of time, you are doubling up your likelihood of lung problems.
Today I have two dust collectors, one in my shop, the second in my garage. Even just going into the shop I wear a surgical style mask, and if I'm going to be making cuts, I put on the ventilated mask in the pix, and turn on the DC. I moved the DC for the shop into an enclosed space next to the shop. The DC has a 1 micron filter, plus a chip collector (cyclone type) that greatly reduced the dust that even reaches the filter. The air goes through an opening back into the shop, and passes through another filter on the way. See pix. My garage unit still has a 5 micron bag, but for now, is moved outside when in use. Will add a drum filter at some point to that one, but can't manage that now.
There are many DC units, starting from about $160 for the basic Harbor Freight model when it's on sale. It is listed at 2hp, but is probably less. The size and power of a DC unit you need depends on your usage, duct setup, etc.
The bottom line to me as an old PR
guy is to tell a tale that makes consequences known in a way that moves the reader to buy some sort of setup before the damage is done. Once the lungs are compromised you cannot recover their full function. Just ask the guys who struggle to inhale and exhale with COPD. There is nothing manly or studly about toughing out sawdust. When you're older and sucking hard to get enough oxygen to make it to the bathroom, it will be too late to reform your ways.
A table saw or miter saw MUST have DC and a mask or you're gonna clobber your lungs. Period. The second picture shows the large shop DC setup. The intake through the wall, the cyclone that spins most all of the sawdust and all the chips down into the barrel. Then on top is the hose that carries mostly clean air back through the blower, where finaly half a percent of sawdust falls down and the Wynn brand 1micron filter on top where the air exist. Then back on the wall you can see another filter over the opening where the air gets one more filtration before returning to the shop. The enclosure is about 10 ft long by 4 ft wide and is perched between my shop shed and my outside office shed. it is fully enclosed and nearly air tight so all warm or AC air from the shop is returned back into the shop. Theoretically, you could just leave the DC and filter inside the shop, but this also cuts down the noise. Machine noise can cause hearing problems, or make them worse--which is the case for more and more young people.
This is a consumer DC thing. DC for industry and professional shops requires much larger DC units, 220 or higher volt power, and can weight a ton, not counting very complex ductwork, blast gates and huge filters.
There is a separate section just for dust collection that can serve as a great resounce for you. This was just recently set up and I think most of the strings on the topic have been moved there. Chip collectors are super important, so you will want to read about the many solutions for their construction.
Thank you for not being promotional about your company. We're generally very happy to be helpful. So, just for me, and at my request, what is the name of your company? I'll look it up. You might also want to identify the filter you folks make that fits on the Harbor Freight unit, which is made in China and sold under many different names. Or you can PM me with that info if you want to stick with the rules around this joint.
You might also want to look up YouTube and other sites that talk about Thien's shop made chip separator. Someone also just posted some tests of a trio of dust separator devices that use cyclones, blowers and in one case a filter.
