This would be a good experiment for Myth busters. I’d imagine that with the lid closed the increase in pressure would not be significant and the air particles would be accelerated more horizontally as opposed to vertically. This would, theoretically, cause them to accumulate more on surfaces below countertop level than above.
The closed lid increases air speed, not decreases it as you create a higher build up of pressure 🤦♂️

But I have no data to support this hypothesis.
They did test it years ago lol and confirmed that closing the lid did not have a benefit.
