Compost Caddy - Replacement Filters 4 "Green Compost Caddy" Mrs Stone 26 April 2010 I have had the compost caddy (item 20341) for a few years and have found it very useful. My only criticism is that the filter keeps falling out of the lid. A note from the team Thanks for placing your review. I'm sorry that you are disappointed with the item. I'll be in touch shortly to help.
