Surely, the requirements are different for a home. For example, how
many combination microwave/exhaust hoods do you see in a restaurant
equipment catalog? And, last I checked, none of the $150 GE
microwaves at Best Buy included provisions for Halon. My restaurant
experience leads me to suspect that a month's worth of buildup in a
restaurant's ducts is more like a century's worth of buildup in a
residential kitchen. Your point, while certainly valid, is a bit of a
stretch.
