Diaper Genie Carbon Filter Refill Tray

These work well and keep unpleasant odors at bay. They're supposed to be replaced once a month, so this pack should last for about 4 months. Incredibly easy to use, just open the plastic sealed bag the filter is in, and put it under the lid of the diaper pail. This has kept the room from smelling like dirty diapers, and after a cesarean section has definitely helped save unnecessary walking, or having to take the trash out more often than needed. They fit perfectly in the Diaper Genie pail I have, but with a thin piece or two of masking tape you could probably use charcoal filters underneath the lid of any garbage pail with a lid (kitchen, etc.). Wish I had known about charcoal for garbage smells years ago.
