TCML,

We use 3M Brand N95 Particulate Respirators when working around high ozone 
concentrations (if you can smell it, it's high!).

The best for our use seems to be the 8214. It's basically a filtered 
welding respirator (fire resistant shell) with Organic Vapor removal 
(activated charcoal) and an outflow valve (for exhaled air). These help 
reduce operator ozone fatigue and keeps our stunt performers from getting 
"the big whiff". They're very comfortable and I even use one around the 
shop to block out sawdust and smelly stuff (fumes from cutting phenolic, 
g10, etc...).

Grainger sells them as part number 4MH63 for $65.00 per 10 pack. Each mask 
lasts for months with our "normal" use.

In the interest of lung health and safety, I would like to humbly suggest 
that The Geek Group or other hobbyist/educational organization undertake 
the group purchase of these for resale to the group. I have a few extras if 
someone wants one right away ($10 per mask, PayPal, US Postage Paid, Email 
me off list).
