Anyone know where to buy replacement cartridges and filters for humidifiers? We have returned from Christmas in the US with a new one and found we need to change the very inexpensive cartridges next month. I'm trying to decide if I have them shipped or find something local.

What brand/model?
You could check the site of the maker in the U.S. and see if they have a Japanese distributor. I don't think these things are generic, but made for a particular model...
