The Exhalation Filter is intended as source control to filter droplets from each breath when used in healthcare settings, or whenever source control is required.

The filter is to be fitted in the AYO HC Outlet Module and can be washed up to 30 times or used for a month. Replacing the filter is easy by removing the Clip-on Cover of the Outlet Module, dropping out the old one, and popping in a new one, all in a few seconds.
