Norpro Compost Keeper Replacement Filter

These filters are specifically engineered for Norpro Compost Keeper units. While they may fit other bins with similar lid dimensions, we recommend measuring your existing filter slot to ensure a proper fit.

For optimal odor control, replace your charcoal filter every three to six months. If you notice odors returning sooner, it is likely time for a fresh filter.

No, these filters are designed as single-use consumables. Washing them will degrade the charcoal's effectiveness and structure, so they should be replaced rather than cleaned.

No preparation is required. Simply remove the old filter and drop the new one into the designated slot in your Compost Keeper lid.

Charcoal filters are highly effective at neutralizing odors, but they cannot eliminate the smell of fresh food scraps entirely. A properly maintained compost bin should be relatively odorless, but you may still detect a faint scent when opening the lid.
