The innovative concave shape of the Dometic ECO filter assures that malodorous gases are completely filtered through activated odor-adsorbing media. The result is more thorough odor elimination and the assurance of more enjoyable boating. Though differently shaped, it is a direct replacement for previous Dometic vent filters, as it fits the same installation brackets as older models. Now made with recyclable plastics, Dometic ECO filter components are much more ecologically friendly than previous Dometic filters, as well as many other current filters.
