Designed for outdoor use, the unit accepts multiple hose sizes, includes upgraded composite filter cotton and a culture chamber for beneficial microbes, and features a simple built-in backflush cleaning action indicated by a rising cleaning marker.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this filter remove visible debris and fine particles?\u003c\/h3\u003e\n\u003cp\u003eThe Three Seconds system uses layered composite filter cotton to tackle both large and small solids, then routes water through a media chamber that supports biological filtration.
