Aren't we also missing the point that we would be exposed to this
concentration only if we were using the strips as indicated, ie. hanging
around the room, when in fact we have them inside relatively airtight,
closed boxes?
The amount of exposure would be many times smaller than the concentration
these strips are designed to be used at, and thus even less dangerous, if
they're dangerous at all.

I myself believe it's far more dangerous to sit in front of the computer
and write this message down.
