Gus... actually both AJ and his dad thinks a lot is little. When they perfume up for the night, it is pretty strong. It only lingers in a room for l0 minutes or so and the aroma is gone...... it has never gone through the heating vents to the basment or fill the house for hours of aromas.. I could still smell the perfume this morning in the basment and when I went upstairs it was still strong in the air.

The reason I question it is because the "house filled with perfume" very close to the time AJ was expected to be home from his night out......I could be wrong and they could have spilled a bottle of perfume/cologne by accident.... Just really didn't smell all that great at 3am.. nor did it smell that great when I got up this morning...

Filters on vents is a great idea. WIll have to check those out.....
