Question about respirators

So last night was my first serious build. I tried to build a sneaky Pete but eventually I ended you a decent jump cue. I have a small m3 painters respirator mask from Walmart but I really believe it is not working. My throat started to hurt last night and this morning it is actually worse. I worked with phenolics, diamond wood, epoxies a lot of chemicals in general.

SO the question is

What good quality respirator should I get that will last, protect me very well from dust partials and gasses.


O here is technically my first cue.
Second coat of poly. Still a long way to got from what I learned in terms of finish.

Same mask and filters I use. The P100 cartridges were called HEPA when I bought them. Same thing though. Make sure you have a good seal when you wear it. Don't make it too tight though. I can wear it for a several hours without it bothering me
 
If you are doing this cutting in your apartment, then a mask is useless without dust collection. A mask will protect you as long as you are wearing it, as soon as you remove it, if the dust is still hanging in the air, you start to inhale it and will continue to until it settles on something. Then you sleep and inhale it also. A vacuum will help, but not alot if not setup right. I believe Tom Hay recently had some medical issues after cutting stuff in his living area. Fine dust can hang in the air 6-8 hours after being released, then can be re-released when you disturb what it settles on.
My advice is to use like a 12 gallon shop-vac, like a ridgid, and buy extra hose and pipe the exhaust out one of your windows when cutting, and use a good mask. Then when done for the day, vac up around the room your cutting in. Doing this will help reduce the chances of you going to the ER.

This is what I've been using when spraying for about 4 or 5 years now and am about to order another hose and mask for sanding:

It blows cool air to your mask and has adjustable air flow so that it can be adjusted to always blowing out from the mask. This positive pressure absolutely stops any contaminants from entering the mask and henceforth - your lungs.

I've owned many masks over the years but not one worked as efficiently as they were supposed to. To work correctly they must fit tightly and the canisters must be changed on a regular basis for them to be of any use. I bought a small forced air mask that had the battery powered air supply compressor mounted on my belt for something like 89.00 from Woodworkers supply just for sanding but only used it a couple of times as there was insufficient air flow, the air was to warm and uncomfortable and the wire kept getting in the way.

This dude that I am using is the best thing since sliced bread. I wish I had bought it 20 years ago.

I have used one of these for 2 years. I change the filters every couple months. Dust clogs them up eventually. The filters don't wear out as they do not absorb anything but they filter out most chemicals.

They are available at Lowes.

You can't smell anything when wearing it. If you can, it's not sealing on your face.

I wear it whenever I am cutting wood, sanding or using sealer or when ever I am working in the shop.

Dick,

That's badass, pretty slick set-up. What kind of mobility do you have with that hose attached to you all the time ?? It's got to get in the way at times doesn't it ??? Or is it just one of those things you get used to over time...

At present I just use it for the spray booth so the hose goes through the wall to the mask and there is little overhang. I need to get another hose so that I can rout it through my shop, out of the way, to the lathe that I do most of my sanding on.

Actually, they have different face masks, hoods and even whole suits. I purchased the hood but didn't like it so I adapted that mask that I already had.

Dave is quite correct. I also am sensitised to the A Component of all Urethanes and Polyureas, breathing them closes my respitory system when I lay down. Please don't go "It won't happen to me". It took 15 years before I became sensitized. No one told us in the 1960's, all that read this thread are lucky. Dollars for safety equals years more of quality life.
 
Very nice, some of these setup's looks really high quality but not in my price range plus I am not at that level yet. For a person that spends a lot of time In the shop it's a must. I went with the 3m multi purpose mask. It has replaceable cartridges and and I believe it will do the trick for now.

Thanks to all for the advice.
I installs a fan in the room, that pulls the air out through the window. Also a air purifier. So between all this and the mask I hope it will be ok. A vac system I believe it's next but i am still figuring out the design.
 
I worked with coatings and drywall for the better part of 35 years including spraying all sorts of nasty stuff. Every time these threads come up it reminds me of watching other tradesman not wear appropriate protection. Fortunately for me I was trained as a young man to take my health seriously and to wear the best masks available at all times. If you can smell anything coming through your mask the fit is bad or the canister is not adequate for the chemicals your using.
