Sealand's new ECO filter marks the next generation of odor elimination.

Its new concave-shaped design allows more air to pass through the activated carbon and absorb more odors. Only fresh air comes out of the device's ventilation tube.

This new cartridge is made with 55% less plastic than the previous model. Made of recyclable material, made of polyolefin (ecologically friendly). It fits perfectly and fits the same mounting brackets as the previous Sealand vent filter. It was the first design change to the original ventilation filter since its inception more than 25 years ago.

It has been proven to be 2.4 times more effective than other activated carbon filters. Absorbs tank odors throughout the boating season.
