About This

KEEP COMPOST SMELLING FRESH: Biostrike’s compost crock filters use premium activated carbon batting to trap and neutralize foul odors at the source-keeping your kitchen fresh and helping deter pesky fruit flies from lingering around your compost bucket.
EXTRA THICK FOR LONGER USE: At 0.44” thick, our biodegradable charcoal filters are twice as denser as typical countertop bin filters. That means better odor absorption and longer-lasting freshness. Replace every 2-4 months to maintain peak performance.
FITS ANY SIZE COMPOST PAIL: Each 5.5-inch round filter fits most standard compost bin lids-and can be trimmed to size for smaller lids in seconds. No mess - just easy, reliable odor protection for any kitchen compost crock.
ADVANCED ODOR LOCK TECHNOLOGY: Engineered with dense, multi-layer activated carbon, our compost bin filters don’t just mask smells—they trap and neutralize them deep within the carbon structure. That means cleaner air, fewer flies, and a fresher kitchen every day.
PROUDLY MADE IN THE USA: Our compost charcoal filter replacements are crafted with care in the USA using high-quality materials you can trust, helping families keep their homes smelling fresh for over 34 years.
