Respirator recommendations?

I always recommend a respirator that will filter organics. Anything less than positive pressure is going to be less effective, but 3M does sell a pretty good strap on mask for organics. You have to reseal it in the air tight bag when you're done with it because it's only good for about 8 hours of in air use, but they do work well and are affordable. I think they are around $30 at autobody supply houses.

- not a recommendation for buying there - but for info. John T.

I bought a 3M one at Home Depot for about $25-$40 but I'm not where I can easily find the model number. But it can be fitted with several levels of dust filter plus organic vapors cartridges. I've had mine for 2-3 years now and I'm happy with it.

how well ventilated is your space

some of that stuff burns my eyes so my choice was a full face mask or go outdoors for the smelly stuff

outdoors works but has limits depending on the stuff you are working with and temps
