[[Image:biosand filter diagram.jpg|thumb|right|250px|A biosand filter diagram. It can remove about 95% of iron (plus many other contaminants). Diagram: [http://www.cawst.org/en/resources/biosand-filter CAWST.]]]

The key components of the filter are outlined in Diagram 1 (see below). Water from the handpump enters the filter and is directed onto an aeration tray. Water droplets fall from the aeration tray onto a few millimetres of standing water before infiltrating into the filter sand. A slotted drainpipe, set into a thin gravel blanket, collects the filtered water which exits via an outlet at a height of 0.45 m.
