It's you in the room and you alone. So you are only spreading stuff to yourself and your family, who you would have already been around and touched, etc. So what is there to be concerned about?
And experts, real MDs not Internet MDs, LOL, have said it can't live on surfaces more than a few minutes.
But still, if I'm the only one (or my family) to be in the room then not sure how it matters. I'm the one that brought in whatever is in there. Right?
