Perhaps a silly question, but how do I know? I've got loads of tanks so each atomiser probably doesn't get that much use, but I'm never sure on when to change them!
Just put a new one in one of my nautilus Minis as a liquid I'd tried before seemed unusually harsh on my throat, but what's the best way to know when it's time to swap one?
