What exactly do I need to look out for to know when it's time for the refill? The description says that it lasts up to 3 months. Depending on the humidity, that will probably be sooner or later. But how do I know exactly when it's time for the refill? When the "stone" has more or less disappeared? Or simply when the 3 months are up? Thanks for any advice in advance!
