•Pack of 7 One pack includes 7 activated carbon filters. One fitler can last approx 2 months 3 months. It will also depend on what is being put in the food waste caddy, the weather and many other factors, so it's possible that it lasts only few weeks. But anyway you can just replace it when you find it is time to do so. Be warned, don't leave them in the bin too long when old or they will grow and accumulate rot.
•Safe Material These activated carbon filters (fibrous) are made of high-quality powdered activated carbon as the adsorption material, and the polymer binding material is used to attach the carbon to the fiber. The thickness is 10 mm, 2 times thicker than the filter that came with Joseph Joseph bin. Thick and dense carbon filters can effectively absorb and capture food odor in the compost bin, they are environmental friendly, tear-resistant and safe to use.
•Perfectly Fit These carbon filters are the same size as the Joseph Joseph ones, 9.5cm(length) and 7cm(width), so they can perfectly fit almost all Joseph Joseph caddy and bins like Totem 60, Totem 48, Totem 50, Stack 4 Food Waste Caddy etc. You don't need to buy other filters in different sizes and shapes that are either too big or too small and you will need to trim to waste. Just in case, it's better for you to make sure whether your bins has a filter replacement fitment and the size of it.
