Question to the science-types (and please answer this one -- the air in our house depends on it!):

Are odors ions? Little bitty bacteria?

We're trying to figure out what kind of air filter to get, now that we have 3 felines. Odor is the major issue, as it's a longer-running problem. (We're already getting desensitized to our particular kitties' dander, so I'm not as worried about allergies. Plus, I could always vacuum. And dust. Keyword here being could.)

We've been borrowing an ionic filter from the MiL for a week, and that seems to have gotten rid of the majority of the odor, but I'm open to the possibility of placebo effects. Various consumer groups online say that ionic filters are crap and do very, very little of anything.

All I know is that the filter we're using has two pretty blue lights when it's running.
