I came across this on Home and Garden TV. It claims to be an odor eliminator that does not use chemicals or electricity. I think that this should be in every iguana (or any other pet) enclosure. Since it is a big disk of stainless steel, the ig can't swallow it. The website mentions its use with fountains, so I'm thinking that humidification systems can use this. The website is http://www.frieling.com/smellkiller.htm
I'm looking for a local store to sell one.
