Wear those dust masks kids....mix your stuff outside if you can.
^^for sure..
I can't do mine outside, so I use a fairly aggressive mask.
I would recommend something rated N95, the level of the swine flu masks..Those cheap ones from the hardware stores offer protection against only large stuff, like sawdust..
I use the 3M Particulate Respirator 8210plus, N95
A little more expensive, but works very well. I have asthma, and have never had an issue using this mask. I don't use Guano's, but I use it
against all the dusts from perlite/minerals/etc..
