A non-sterile filter designed to be installed in a continuous positive airway pressure (CPAP) and/or bi-level positive airway pressure (BPAP) unit to filter particulates from the ambient air prior to inhalation; it is not intended to filter medical gases. It is typically a flat sheet or pad composed of tightly woven materials or foam intended to be installed over the air inlet of the CPAP/BPAP device to remove particulates/impurities; it is not intended to filter microbes. This is a reusable device.
