Camco Marine Holding Tank Vent Filter Kit

The Camco Marine Holding Tank Vent Filter Kit eliminates odors released from your boat's holding tank vent system. This activated carbon filter kit features granular activated carbon (GAC) specifically engineered to absorb and neutralize odorous gases before they escape, addressing one of the most persistent issues boaters face when operating in confined waters or crowded anchorages. The complete kit includes the carbon filter element, mounting bracket, and standard 3/4-inch garden hose connection fittings for straightforward integration into existing vent lines.

Installation is direct and requires no special tools—the filter mounts inline to your boat's vent hose using the supplied bracket and fittings. The granular activated carbon media works by trapping odor-causing hydrogen sulfide and methane compounds in the vent exhaust, preventing them from venting into the cabin or throughout the vessel. The compact design (3 x 3 x 16 inches) fits neatly in engine compartments or locker spaces without consuming valuable storage real estate. The carbon filter element requires periodic replacement as it becomes saturated; replacement filters are widely available and maintain the same 3/4-inch connection standard.

This holding tank vent filter is essential for cruisers and live-aboards who spend extended time on the water, where odor control directly impacts comfort and quality of life aboard. Weekend anglers and offshore fishing boats also benefit from reduced galley and head odors during multi-day trips. The kit works with standard RV-style holding tank systems and marine sanitation devices (MSDs) using 3/4-inch vent hose, making it compatible with most modern recreational vessels. Replacing or upgrading to an activated carbon vent filter is one of the most cost-effective modifications a boat owner can make to improve the onboard environment.
