when its all gone, it will slowly disolve into the water as long as there is a piece in there there is ome to dislove into the water....I think I just might replace the sponge once a month as in a fish tank...either that or do the silver thing. I think a sponge might be cheaper though. You can buy a big cut-your-own filter sponge and cut it down to fit the humidifer. Only problem is you'd have to cut the original off. I guess you could tape it to the lid. Look! Duct tape has invert uses too! As for the silver, when should we replace the silver wire in the water?
