The improved iron and manganese removal filtering device converts low-valent manganese and iron ions in the water into high-valent manganese and iron ions through an oxidation reaction between oxygen and water, and the ions are filtered and adsorbed by the filter layer, and then the residue is filtered out by the second filter layer.
