A tree branch filter uses the properties of sapwood to purify water.
Xylem tissue (the younger wood in concentric circles between the center heartwood and bark) is able to filter water, removing impurities including bacteria. Viruses, however, are likely to pass through the filter – therefore this is not a fully satisfactory solution on its own.
Cautions
Care should be taken to avoid varieties of wood which may be poisonous.
