Inline Antibacterial filters are not recommended (especially in APAPs) because they do affect the ability of the machine to sense whether or not a pressure increase or decrease is required.
"I" personally would never use one.
The filter itself does an adequate job.
Using the ResMed Mirage SoftGel Nasal Mask with a chinstrap
I do not use either the Ramp nor the EPR Comfort features
Have been on CPAP since December 1998
This is my 3rd machine
I use the ResMed ResScan Software (Version 3.16)
Why do you want one?
Unless you're changing the filter every night, you're probably going to get more bacteria with the filter than without it. The filter is going to be a nice humid place for germs to grow.

If it's midnight and a DME tells you it's dark outside, go and check it yourself.
I sleep in dirty old New York City with a Respironics ASV Auto. On the air input side I use both a foam and the white fine disposable filter. (side note: Medicare & Ins. generally allow for 2 white filters a month - mine is filthy black after a week and needs replacement that often). I have a heated humidifier (but not tube) and use an in-line bacteria filter from Respironics at the output from the machine (between the PAP and the tube). THAT filter generally becomes grey and needs to be replaced every 2 weeks. I have not had a problem with the in-line filters affecting the pressures from the machine or its sensitivity and ability to adjust pressures for treatment. If you tip the machine for some reason and water splashes up into the filter you need to replace it immediately as it then will block air flow if wet or dampened, even if dried out. I also made the mistake of purchasing NON Respironics filters one time, and they caused pressure problems. Spend the extra 25-50 cents per filter.
Remember, you are breathing into your lungs the air being pushed through the machine and humidifier. If you can make the air cleaner, it is not such a bad idea!
All that said, below is "tips" for the product from the website of a supplier.
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
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:
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.
