The Universal In-Line Bacteria Filter is used as an outlet filter. It is placed between the outlet on the machine and the hose/tubing.
It is designed to filter the air as it leaves the machine before it reaches your mask.
This added filter used in conjunction with your machine's pollen and particle filters help insure that the air you receive through your mask is as pure and clean as possible.
NOTE: It is not recommended to use the Bacteria Filter when using an Auto CPAP as it can interfere with the APAPs ability to deliver the correct pressure due to airflow restriction.
