"Composting is a healthy way to take your old food and turn it into something healthy for plants and the environment. Using a composter is a daunting task at first but once you get the hang of it, you learn a thing or two. However, if you want to continue composting, you’ll need to change your filter. The Natural Home 2-Pack Replacement Composter Filters features filters that are 18cm in diameter but their material is delicate enough that they can be cut down to fit the right size. This little filter isn’t just for the compost. By using a filter, you can maintain fresh air during the process to make it much more pleasant. They last up to six months and should leave about 1cm around the edge to fit properly. "
