A device for filtering air that is to be breathed through a tracheostoma, to simulate the role of the nose particularly in patients who have received a tracheostomy comprises a filter (20). The filter comprises a pre-filter (21) formed from electrostatically charged fibres, a first layer (22) formed from activated carbon and a second layer (23) a hydrophilic material such as one that is based on regenerated cellulose material. The filter includes a layer of adhesive by which it can be held in place when in use, and a cover layer (24) on its exposed surface. |
