How do these companies come to that conclusion? I think most people start to smell after only 24 or 48 hours max so how do these companies get 72 hours out of their testing?
Im assuming they’re fudging their numbers but at what point does it become false advertisement?
Technically it’s probably a defensible lie.
They do a very unrealistic lab controlled experiment saying that it retains 50% of it’s odor suppression after 72 hours.
I think there is a fine print or asterisk that says “reapply every 12 hours” thats how they get to 72 hours.
