Bacteria filters are fine enough to remove some bacteria and are clinically indicated when a CPAP machine is used by more than one person. However, many CPAP users find them helpful in reducing the occurrence of sinus infections and other nasal issues. Bacteria filters can be used with an CPAP/APAP/ or BiPAP machine.
Bacteria filters are housed in a plastic frame and are placed at the CPAP air outlet, rather than the air inlet. They may be used with humidifiers, but should be removed and allowed to air dry during the day.
This filter is placed at the air outtake for your machine if you are not using a humidifiers. If you are using a humidifier, it is placed at the air outake for your humidifier. The bacteria filter is placed in the air outtake and the CPAP hose is placed on the other end.
The entire housing is disposable and should be discarded as soon as matter becomes visible. A clogged Bacteria filter may affect the amount of air delivered by the CPAP.
An example of a bacteria filter is shown below. Follow by an image showing how it installed.
