The AIRMAX Nasal Breathing Device is available in two sizes. Small and Medium. 

Everyone has different sized nasal passages, we find that the MEDIUM size Airmax fits most people comfortably. If you have a particularly smaller nasal passage, we recommend the SMALL size Airmax would best suit your needs.

Most people start with our Trail Pack – which is a great way to work out what size you need. The trial pack consists of one of each size – the Small and the Medium and a snap lock case to store it in when not in use. We also offer the Small and Medium in single and double packs.
