Control the air quality on your boat with the ECO Holding Tank Vent Filter Kit. The ECO Kit (309311001/9108823047) will keep the odors from the holding tank in check and include the replaceable vent filter cartridge, a mounting bracket & hardware and hose adapters you need to connect to your system.

ECO Holding Tank Vent Filter uses advanced odor removal technology to keep your boat's holding tank fumes under control as it stops smells from escaping from the tank. The ECO Filter is designed as a direct replacement to other SeaLand and Dometic vent filters. The ECO filter retro-fits the older Sanigard model and the included installation brackets and hose adapters are included for new installations. The kit includes adaptors to fit the most popular vent hose sizes. (Threaded adapters are included for replacement on many older holding tank systems with built-in vent filters.)

The ECO replaces the following part numbers:

  • 309310001 - 5/8" Replacement Filter Only, No Bracket
  • 309310002 - 5/8 in./16 mm SaniGard vent filter complete kit
