Heated Hose/Tubing Compatibility
CPAP/BiPAP machines that are using a heated hose/tubing which is specific to that machine and require a specialized connection are not compatible with the In-line Bacteria filter. The In-line Bacteria Filter cannot be placed between the machine and the hose/tubing connection. In this case, the In-line Bacteria filter could be used between the Hose/Tubing and the mask if desired and will add bulk at that connection.
Examples of machine specific heated hose/tubing are:
- PR System One Heated Tube for 60 Series Auto CPAP Machine
- ClimateLine™ Tubing for S9™ and H5i™ Climate Control System
- Thermosmart Heated Hose for 600 Series CPAPs
The In-line Bacteria Filter is compatible with the Hybernite Rainout Control System, fitting between the hose and the machine.
Maintenance and Care
The length of use of the bacterial filter varies between users and environments. The filter should be replaced when there is debris seen on the white filter material. It is easy to see the condition of the filter through the clear acrylic globe. Replace the filter when it becomes discolored. If the bacteria filter becomes very dirty or wet, machine performance may be affected.
Heated humidifiers can cause water to collect in the filter chamber, thus clogging the filter and adversely affecting therapy. If wet, remove the filter from the machine and set out to dry. Dry time may vary.
Auto Adjusting CPAP Machines
This filter may have an impact on the ability of any Auto Adjusting CPAP to accurately respond to airflow restrictions during use. If the average treatment pressure is below a pressure of 7cm H2O this should not be used.
CPAP and BiPAP machines with Auto On/Off Feature
The Auto On/Off Feature has a difficult time sensing air flow, which helps determine whether the machine is in use or simply blowing air. Our tests show the Auto On/Off feature does not work with the following machines:
- ResMed S8 Vantage
- ResMed S8 AutoSet II
- ResMed s8 VPAP
- ResMed s8 VPAP Auto 25
- ResMed VPAP Malibu
Installation Tips
If a Whisper Cap is used on an M Series machine without a heated humidifier, the Whisper Cap will not fit if used together with a outlet bacteria filter. If you wish to use both a Whisper Cap and an outlet bacteria filter without a heated humidifier, then you should add a Hose Quick Connect or a M Series Tubing Swivel between the CPAP machine and the outlet bacteria filter.
A bacteria filter will not install directly to the air outlet port on the IntelliPAP Heated Humidifier as there is not enough space for the filter. IntelliPAP humidifier owners can order the FlexiTube Angle Adapter for CPAP and BiPAP Machines to provide a spacer between the humidifier and the bacteria filter. The CPAP hose can then fit onto the other end of the bacteria filter.
The In-line Bacteria Filter will fit directly onto the air outlet port for the following machines but will not fit snuggly onto the humidifier for these machines . The FlexiTube Angle Adapter for CPAP and BiPAP Machines can be used to connect the In-line Bacteria Filter onto the humidifier for the following machines:
- Zzz-PAP CPAP Machine
- Puresom CPAP Machine
- EVO 804 APAP
The In-line Bacteria Filter will fit directly onto the air outlet port for the following machines WITH humidifier but will not fit snuggly onto the machine WITHOUT humidifier . The FlexiTube Angle Adapter for CPAP and BiPAP Machines can be used to connect the In-line Bacteria Filter onto the following machines without humidifier:
- RESmart Machines
Please Note: Per the manufacturer, the following warning is extended for children and those who are pregnant or breast feeding. The In-Line Outlet Bacterial Filter may contain phthalates which may cause adverse health effects.
Cleaning and changing filters is the only maintenance required for a CPAP machine.
The filters are located at the back of the machine at the air intake.

If the paper filter has a tab, fold it facing out of the machine for easy removal. The foam filter is inserted into the filter area after the paper filter is installed. The foam filter will catch the larger dirt particles first.
If you are using a two colored filter, the colored side faces out as shown in the image below.

Disposable filters and bacteria filters are not intended to be cleaned but rather changed out, disposing of the used filter. Manufacturers recommend changing the disposable filter once a month, more frequently if used in a very dusty environment.
Disposable fine filters and bacteria filters should be discarded as soon as they become discolored or at least every 30 days.
If you live in a house with pets or smoke, you may need to replace the filters more often.
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.


I don't use these filters very often but when I do, I am glad I have them. Most cases, the time that I usually use them is when it is allergy season or visit a home that has cats. Being this helps keep you from getting forced air that includes cat dandrum into your nose while you sleep at night, it makes for a better waking experience in the morning. more...
I have used the nasal pillow version of this mask for 10 years. Since Breeze discontinued the pillow version I tried this mask. It is TERRIBLE! Leaks, uncomfortable, hard to adjust. Bring back the nasal pillow version PLEASE. more...
Install it and you will suffer suffocation due to air blockage
I purchased this to add to the air quality which is very important. Since I used the heated hose , I couldn't use this filter at the back of my CPAP unit. I had to use it at the end of the hose. My Philips Respironics Dreamwear mask allowed me to install the filter between the end of the heated hose and the mask intake. However, the filter size makes this setup somewhat uncomfortable since the filter is now swiveling on top of your head when you move around during sleep. I took it off after a few hours sleep. I don't know if this would bother others using this setup, so I can't discount it's usefulness. If the filter housing was designed as a elongated tube rather than a round disk shape, it would be more feasible to attach it to the exhaust end of the heated tubing IMHO. The filters are reasonable priced and I would recommend trying them, especially if you have the standard unheated tubing. My wife used them on her old machine and they do help filter the breathing air going into your mask. more...
