Bacteria filter help

Just now received my first order of bacteria filters for my cpap. No instructions - can anyone out there give me some help on this? Thanks

I cannot help but wonder why a bacteria filter would be needed.
There is a nil chance of pathogens being spread from the tank. Maybe one in a
zillion.

This leaves the ambient air in the room.
How do you or anyone else in the room filter this air that you breathe at all times you are not on PAP?????

What is the reason given for marketing them?

I've got mine put on the HH, between the HH and the hose fitting

I agree with previous posters, but to answer your question (since I don't have your machine), I'd either pose that question to wherever you purchased your equipment, or search for "more info" on that equipment on cpap.com.

Hope this helps.

Previous post is correct. The filter goes on the outlet side of the humidifier and the hose attaches to the other side. If no humidifier is used, the filter is placed on the outlet side of the machine.

Note that the Inside diameter on one of the holes in the filter housing is larger than the other. The large hole goes on the humidifier or the machine.

I ask again why this is even desired?

I assume it is designed to not affect the flow, but I cannot understand how anything fine enough to filter bacteria would not restrict the air flow.
I do not understand lots of things though.

and again I ask what you use to filter the same air you are breathing at all times you are not connected to APAP?
Why is this not a concern for all others sleeping in the house not on XPAP?

Tom, I never knew such a 'device' existed! I replied to post, thinking it was referring to the cpap machine !

I must agree with your theory that the flow would be restricted to some degree, and if not part of the INTENDED use by the manufacturer of the xpap machine, there would be hardship on the machine.

Certainly (I'm hoping!) the mfgrs had thought all of this 'stuff' over, and would have made it a mandatory part of their equipment, and calibrated the motor accordingly.

Negative on that, it has to go on the inlet side of the humidifier. If the bacteria filter gets wet, nothing good happens. So if you can't stuff it on the inlet side (as will be the case with integrated humidifiers) you can't use it.

These filters were originally designed for the old BiPAP S/Ts. A clip from the instructions:

These were for in-hospital use, where bacteria filters were usually policy.

But you're right, why filter CPAP air at night, when you breath unfiltered all day long?

plus for filter - you take out the filter and you got a quick connect piece of tubing so hoses last longer

minus for the filter - I have read they screw up response for APAP's (not sure if all pressure ranges but beware)

Just get a quick release connector if that's what you're looking for....
