The OASE FiltoClear Series offers industry-leading, all-in-one pressurized pond filtration ideal for medium to large water features, including fountains, pond-free waterfalls, formal spillways, and traditional water gardens. Each unit in this family delivers mechanical and biological filtration alongside a powerful ultraviolet clarifier (UVC) — all in a compact, impact-resistant body that can be discreetly buried and camouflaged with the optional FiltoCap rock cover.
With Easy-Clean Technology, a 2-way valve system allows you to backflush the filter and redirect waste without opening the unit. Internal filter foams in three densities provide comprehensive filtration, while a UVC indicator window and pollutant level monitor offer at-a-glance diagnostics and lamp life tracking — all without disassembly.
