cold mist humidifier that doesn't need replacement filters?

[knaidel]

We want to buy a humidifier for DS's room. We have a Holmes in our room, and while it works well, we are always buying replacement filters for it- about every 3-4 weeks at $10 each. Although this doesn't exactly break the bank, I'm looking for something a bit more economical.
I read on this board- someone had purchased a warm mist humidifier at babies r us that doesn't need replacement filters. She was very happy with it- it was pricey , at about $85, but worth it.
Does anyone know if there is such a thing for a COOL mist, not warm? Any ideas?

Thank you!

We have a Hunter Care Free (I think?) cool mist humidifier and it doesn't require filters, which thrills me to no end! We bought it at Walmart.

We also have the Hunter Care Free humidifier. We bought ours at Sears.
