How long do they last? I think my wife tried some of those before (although I think they were a cheaper generic rip-off of renuzit) and yes, they did very good at masking the smell, but they dried up in about a week and that was it. But still for under a buck, you can't go wrong. It would still be far cheaper than a carbon scrubber system.

Thinking about it, I might pick up a few of these today and see if the name brand does better.
