Have you ever had one of those days when you walked into a communal restroom ready to relieve yourself, you found that someone is occupying one of the privacy stalls, and then all of the sudden you get that burning sensation that every aveoli in your lungs is systematically being destroyed by the stench that preoccupied said restroom? And I'm NOT referring to that natural methane by-product produced by humankind (I'm not that juvenile). I'm referring to the manmade aerosol chemicals crammed in a pressurized metal enclosed container. I sometimes find that I'd rather bath in the gaseous by-products of the Mexican bean soup that you had last night instead of having my sinuses and lungs being eradicated by acidic fumes created in a guise of a family household product.
Maybe we need to install better exhaust fans in our restrooms. Or maybe we need to eat more foods that create less gaseous waste. But some of these air "fresheners" wil eat your insides alive.
