The Mira carbon filter ensures greater freshness in the litter box and works five times better than conventional filters thanks to activated carbon. It absorbs odors longer and more effectively. These carbon filters are specifically designed for the Mira litter box and fit perfectly to ensure optimal function. To keep the litter box permanently odor-neutral, we recommend changing the filter every month. These filters are essential for pet owners who want to efficiently and sustainably reduce unpleasant odors.
