The first major change to the original SeaLand vent filter in over 25 years,
The innovative concave shape of the SeaLand ECO vent filter assures that malodorous gases are completely filtered through activated odor-absorbing charcoal media. The result is more thorough odor elimination and the assurance of more enjoyable boating.

It is a direct replacement for previous SeaLand and Dometic vent filters and fits the same installation brackets as older models.

Now constructed using recyclable plastics, all SeaLand ECO filter components are much more ecologically friendly than previous SeaLand filters and many other current vent filters.
