In-line Bacteria Filter

In-line Bacteria Filter how do these work does anyone here use them I looking at them because of allergies do they work???

Thanks

I use them between the hose and my mask. On the Oracle 2 mask, there is a diffuser that looks like a small filter where the exhaled air exits the mask. WIthout the inline filter, this gets pretty dirty after a few days. So I assume since this is exhaled air, that ucky stuff is going directly into my lungs. With the inline filter, the diffuser stays pretty clean for about a month of so. No ucky stuff.

With allergies, this should cut down on pollen, etc. that can travel through the system.

Respironics and other vendors make an ultrafine filter that fits into the regular filter slot between the regular gray filter and the air intake. You should be using one of those at a minimum. On my machines, placing one of these ultrafine filters sometimes causes both filters to be on the table in the morning so I have a rubber band around the machine to keep them both in.

The inline filter between the humidifier and the hose does wonders for my allergies. I think of it as and extra benefit of xpap. I get to breathe extremely clean air.

I just want to caution that adding this filter can change the performance of your machine. In my machine's manual it states "When using the bacteria filter, device performance may be affected. However, the device will remain functional and deliver therapy." In another area of the manual it states that "Dirty inlet filters may cause high operating temperatures that may affect device performance."

So I'm not sure entirely what they mean by "device performance" (and if they even mean the same thing in both cases!), but I would be concerned about the proper pressure being delivered, the ability of the machine to record data accurately, and the machine working hard against the filter and shortening its life. I don't know what the risk is of any of these, but it's something to keep in mind.

I read that it slow the pressure a bit not worried about that . I hope that they dont mess up the data recording that kinda what I would like to know.
Thanks for the help..

Don't have any experience with this, but we did go camping or rather RVing at a full hookup site, so I was able to use
my cpap and O2 concentrator, but there was huge pollen, mega pollen, here in Colorado, totally consumed and dusted
everything. I'm going to check out my filters on my cpap machine now before nighty night time.
I have not heard of a bacterial filter before?

I tried these filters out between my Mseries cpap and mask, first night it worked ok, but half way through second nite the humidity clogged the filter making it hard to inhale. After drying it out subsequent nights it would only last part of the night before clogging up. I don't recommend these if you use a integrated humidifier.

The bacterial filters are generally not used by people on their home machines. They are meant for multi-patient use machines (like at a hospital or sleep lab). They prevent bacteria from a patient getting into the machine, and then getting transferred to the next patient. They go in-line with the breathing circuit, somewhere between the patient and the machine. They are pretty much required for multi-patient machines, but generally not necessary for a single-patient machine, since any bacteria that you might transfer to yourself you already had.

cowlypso is correct that these filters:

were originally designed for use on multi-patient machines. That doesn't change the fact that they effectively stop pollen, which was the OP's question.

Also, the information about the filters says that they can effect therapy at pressures of 7 and below. My pressures are considerable higher, min EPAP=10.5 cm. My data reports don't look any different with or without the filter. Since OP has a data-capable machine, he can do the same test I did (with vs. without.)

Thanks HD That what I was looking for I bought one today from the Local DME Im going to try it out tonite I hope that it helps.
