RED FACTOR 8-Pack Extra-Thick Activated Carbon Charcoal Filters for Kitchen Compost Bins (4 Round 6.50-inch, 4 Square 4.5-inch) 0.4 inch (10 mm) Thick

Keep indoor composting completely odor-free with RED FACTOR replacement filters. Built with activated carbon (active charcoal), these filters neutralize unpleasant smells—even on hot summer days—so you can continue adding food scraps like fruits, vegetables, coffee grounds, egg shells, tea bags, and more without worrying about odors. What’s included and longevity: 8 replacement filters per pack (4 round and 4 square). Each filter lasts at least 3-4 months, giving you more than a year’s worth of odor control from this set. Size & fit: The round filters measure 6.50-inch in diameter; the square filters are about 4.5-inch on each side. At 0.4 inch (10 mm) thick, these extra-thick filters block odors while their porous structure supports the ventilation needed for healthy composting. They are sized to fit most indoor compost buckets right away and can be trimmed with scissors if a smaller cut is required. Simple replacement & care: To swap filters, pinch the old one from the side to remove it from the lid, clean the lid, then insert the new filter making sure it sits straight and fully covers the vent opening. These contain active charcoal—do not rinse or wash the filters. Satisfaction guarantee: RED FACTOR is a small independent company focused on quality and customer care.
