Oh no I was asking the person I responded to.

I second the Airmega Ap-1512HH! I've got two of them, they do a great job when grass harvest season comes, or when the smoke rolls in from fires.

I'm really interested to know why your opinion about this is so strong lol. Also not all that much has changed about how much skin people shed, I'd bet. Maybe the remaining percentage is significantly different because of all the materials we've discovered since the 50's, but the skin fraction should be about the same?
