One of the big changes in the RouterForums since I joined, and one of the changes for the better is overt recognition and discussion of dust control.

That said, I am somewhat surprised that so far in this thread there has been no mention of face masks. The most dangerous particles are those in the 1 micron (1 micrometer, 1 Ám) diameter rough particles. These particles are roughly the size of bacteria, and the body essentially deals with them as bacteria. So they readily get from lung alveoli to blood stream, whereas larger particles do not. Toxicity is a different but equally important issue. The last line of defense for a woodworker should be a NIOSH N95 spec face mask. the spec requires blockage of 95% of particles 0.3 Ám diameter, the size of some viruses. These masks are very economical and readily available from such places as Lee Valley and Rockler. One disadvantage is that facial hair can prevent a seal. It makes no sense to me to spend hundreds on dust collection but not spend tens on packs of 10 or so disposable face masks.

Good stuff right here. Since I don't have any sort of dust collection besides an old shop vac, i'll be using a mask for sure. 1 micron - as I learned above!

thanks!

Like Tom, (mftha) I ALWAYS wear a dust mask when cutting wood in my shop. I do have a dust collector that is always in use as well, but, and this is MY opinion here, I don't believe ANY dust collection system catches all the dust. I have plans to start using a box fan with a simple furnace filter taped to the intake side. This is to catch most of what is floating in the air. I know it won't catch all of it, and certainly won't catch the fine dust, but it's better than what I have now, which is nothing.

PLEASE! Do yourself a favor and just buy one of these: https://www.amazon.com/WEN-3410-3-Sp...dust+extractor.

You can't really get the same filtration and air flow rate from the fan/filter combination--I tried and the difference between the two methods is noticable. It is about $130, that's all, and also check out the Harbor Freight 2hp DC unit, which goes on sale from time to time. I bought mine for $187 on sale with a 20 percent coupon. The difference is amazing, and it will cost you much less in the end than that to try to patch togther a home made system that won't work as well. The tiny particles do not come out of your lungs, every day you delay doing proper DC, is another day of damage. And, some of that sawdust is actually carcinogenic. Masks, DC, air filters all can give you extra years of happy life. Invest in your own wellbeing.

Boy...did I screw up...

Title was supposed to say "Isn't fine dust bad for you"...pointing out the open can (in the video) that the planer was blowing into and that it would spread sawdust all over the place.

But thank you all for the concern and advice...it's good that forum members watch out for each other...

Thanks

Nick

Hey Tom Grizzly tools has an air filter system on sale for Christmas and it is cheaper than the WEN one. The Grizzly is $99 as of a couple of days ago. Check it out. It looks the same as the WEN unit.

I thing the Griz and the WEN are identical units. Whichever is cheaper, but since I have Prime, there's no shipping charge. Not sure what Grizzly charges for shipping, but I got the WEN before the Griz sale.

The more I do, the less I accomplish.

Changed albeit a little late. It has gotten a conversation going and information has been exchanged which is always a good thing.
