I didn't realize the particles were that much smaller- and no , my filters
aren't HEPA so I'm thinking you right, they won't stop the particles, and no
doubt being outside really isn't going to help any.
Very good info to know, and since Black Beauty is that cheap, it's a no
brainer.
Thanks a bunch!!!!
