My wife is going to light up when she hears about this one. Ventex Systems has what it's calling the world's first odorless toilet. Its patented exhaust system draws the contaminated air from the toilet bowl, preventing it from spreading throughout the room. I've been in a couple of gas station restrooms that would benefit from this technology. The toilet is apparently the result of 10 years of research based in Canada. I didn't know so much energy was devoted to this vexing problem. Ventex's toilets also use less water per flush, so you're not only saving the air from your stinky fumes but you're also saving the environment. It can be ordered online from their web site.
