ABSTRACT:
A smog and dust filter for a tracheostomy tube which easily adapts onto existing tracheostomy tubes to filter out dust and airborne contaminants. The light weight and unobtrusive filter is easily manufactured and quickly installed onto an existing tracheostomy tube. The filter includes a securing device for engaging the outer periphery of an open end of a tracheostomy tube. A filter element, having two or more layers of net material, is attached to the securing device. The layers provide a filtering membrane to separate airborne particles and contaminants from an inhaled air stream.
