The In-line Bacteria Filter is an additional filter to help allergy sufferers and would also be extra protection for people with infections or lung diseases. They have a bacterial and viral efficiency of 99.9%. The filter cleans the air as it leaves a CPAP, BiPAP or Ventilator machine before it enters the hose and mask, and is used along with the machine's built-in inlet filters to provide the cleanest air.
It is a recommended CPAP supply compatible with almost all machines, and the average time people are using one filter is between 1 and 3 months, but it is easy to see when they need replacing through the clear filter cover as dirt will cause the filter to change from white to grey or black, and it is important to change them when this happens! Some people will 'feel' when to replace them if their symptoms reappear (such as allergies, nasal congestion, wheeziness etc).
A single Filter can be purchased, or you can buy a Pack of 5, which is more cost-effective and also makes it easier to identify with a new one when to change the one in use by comparing the colour.
The In-line Bacteria Filter cannot be placed between the machine and the hose/tubing connection on machines which come with heated hoses, such as the Resmed's Climate Line Heated Tubing with the S9 and Airsense machines, Fisher & Paykel's Thermostat Heated Hose or the Respironics' own 60-series Heated Tubes. In this case, the In-line Bacteria Filter could be placed between the hose and the mask, but bear in mind this will add weight at that connection. However, the Bacteria Filter CAN be used with the Hybernite Heated Hose.
You will need a CPAP Hose Swivel Adapter for use with the Devilbiss Sleep Cube (Intellipap) Machine ONLY if you are using the fitted Heated Humidifier with your machine.
If you are using an APAP machine with automatic pressures which average out lower than 7 cm, please do not purchase these as they 'may' affect the airflow.
If the Bacteria Filter gets accidentally wet, allow the filter to dry before use.
Do not allow the filter to get too dirty before replacing with a new one, as this could affect the airflow.
