That no company (yet) has embedded an air freshener in a furnace air
filter.

My wife if company is coming and the house smells like last nights dinner
sprays
air freshener or perfume on the furnace filter before they arrive.
Even in summer, she just turns on the fan.

You want us all to have to put up with homes that smell like walking into
Yankee Candle? It would cause the biggest wave of mass suicides the world
has ever seen.
