Filha is a non-governmental public health organisation (NGO) fighting against tuberculosis and lung diseases by implementing prevention and treatment programmes, educating health care professionals and enhancing networking of experts. Filha acts nationally in Finland but also in its neighbouring areas and in areas of less developed health care infrastructure.

Filha was founded in 1907 and is thus one of the oldest public health organisations in Finland. Since 1997 Filha acts as a WHO Collaborating Centre for Prevention, Control and Treatment of Tuberculosis.
