Nice post @doitvoluntarily!
I do think that anything that can remove the scent of wafting sunk will sell.
We've been looking into units to sell in our cooking supply shop that contain the smell of decarbing cannabis and I like this option a lot for handling smoke and vapour. I don't smoke myself, but I do a lot of cooking and some vaping. I can tell you, the smell is a huge issue for some folks.
