   Vern,

   I use the 3M 7502 (medium face) half-mask with the 3M 2091 particulate filters. In my research, this mask and filter set appeared to satisfy my needs for a dust mask. I have used this mask for sawing at the table, routing and ROS sanding with 220 grit. In all cases I have not detected any wood order or dust leakage. Prior to using the mask I would cough for 30 minutes after a wood session and my nose would be clogged for most of the evening. I do not suffer any of these problems when I use the mask.

   When the mask is placed on the face, the seal between the face and mask is completely secure. Breathing is normal, however, the sound of breathing is greatly exaggerated - sort of Darth Vader like.

   There are numerous other filters available up to nuclear waste filtration. The 2091 filters are about as low end as they make since they are only rated for non vapor particulate matter and allegedly filter 99.5% (or thereabouts...don't remember the exact number).

   The mask was $20.64 and the filter $5.16. I bought these from monstersafety.com or (888) 823-1233. I highly recommend this combination. You can purchase the full face mask for an additional few dollars but I don't have the catalog number. 3M has good descriptions of the system and respirators in general.

   Hope this helps,

   Burt

   Thanks for the info. That is one I had not thought of.

   Is this the Trend respirator you are thinking of?

   If it is, then I can recommend it. Many woodworkers in the UK use it. It has one big advantage over other designs, and that is the very large surface area. This means that it is very easy to suck air through it, unlike other makes where the filters are only maybe 3" in diameter

   The main drawback is that it does block more of your downward peripheral vision than other makes, so you need to be careful not to trip over stuff

   Hey John, Thanks so much for sharing your experience. I will keep the vision factor in mind. I plan to go to Seattle and try both of them on Friday.
