With 6 replacement filters, the Filter Set for the Garland Kitchen Compost Caddy will keep the smell of composting material from filling the kitchen the whole year long. Each filter lasts for 3-4 months.
There are only two of us, but we eat a lot of vegetables. This size fills in about a week for us, and the lightweight but tight construction with handle makes it easy to take it out to the compost bin. The filter seems to work well, no smell detected in our kitchen during the week.
