ELF is a patient-led organisation that works internationally to bring patients and the public together with healthcare professionals to improve lung health and advance diagnosis, treatment and care.

Founded in 2000, ELF works in partnership with the European Respiratory Society (ERS) to develop the union between lung health professionals and patients. Based in Sheffield (UK) and Brussels (Belgium) ELF has grown and developed a core team of specialists and a network of individual patients and patient organisations. ELF works with people from all over the world, including our volunteer patient network of more than 350 people and our patient organisation network with more than 200 respiratory organisations in Europe; working together with people living with more than 40 different lung conditions.

Our ethos is openness, inclusiveness and collaboration. We believe in working together to improve lung health.
