Umm... nothing gets *IN* is all I was discussing Nathan. No biosafety cabinet kits imagined.

The calm laminar, (in sheets), flow of air starts after the filter and any air diffusing
evening out slot patterns then flows through the chamber and out a door.
The door is outflowing enough clean air to continuously evenly push dirty
outside world air out the door so no dirt gets in that way.

There are types that intend to keep dangerous pathogens inside a box, but I am speaking of
the "keeps dirt out for culturing" purpose here.
