These filters are versatile and effective for use in various types of garbage cans and compost bins, as they can be easily affixed under the lid without the need for a built-in filter compartment. They are designed to absorb and neutralize unpleasant odors, maintaining a fresh and clean kitchen atmosphere. Each filter is individually sealed to preserve its full adsorption capacity until use. The included Velcro allows for easy attachment to any trash or compost can lid, even without a deodorizer section. A pack of 8 pods provides up to 3 months of odor-absorbing power, offering an affordable and long-lasting solution for odor management in your home. Please note that the trash cans are sold separately from the filters.
