I have a full face respirator mask with dual inhalation filters rated at N95 but the exhale valve appears unfiltered. Does that mean I’m getting some protection but others around me are getting my raw exhalations?

That’s what I thought. I’ll save that for its intended purpose and stick with my paper N95 masks when interacting with others.

So Chicago and Detroit?

Have you read Joe Sutter’s book about the program to create the 747?

Actually, you do. I learned this late in life from my co-workers from other cultures. Haggle everywhere, every time. Works way more than you might imagine.
