Never know which is the 'right' side to fit exposed to the rubbish - smooth or rough. However, they do work - provided I can get my other half to close the caddy lid! Seems to think exposing the rubbish to air is more effective for composting the rubbish; but that defeats the object of the filters!

Purchased these to replace mine that came with compost bin. However, too big to fit lid and says to cut to fit. Cut, but took too much off edge, too small then to fit insert and fell straight into bin!! Take care not to trim too much off filter!

Lakeland round replacement filters are excellent and keep my food waste caddy free from odours

I regularly buy these replacement filters for my mini compost bin. They do the job and are good value

A re-purchase for my grandparents' food waste bin. They think these work very well at keeping the smell to a complete minimum, as well as being easy to 'install'. For them I rate these highly
