how to clean gear after illness?

Now, cover the two holes in the elbow and exhale. Air will come out of the hose connection, unless your QFX is built differently from mine.

Sure, if you block the two exhaust holes, the air bends the flapper valve and goes up the hose. But that is the risk people take who sleep with their hand over their mask vents. I suspect there are few who do that.

If you exhale into the mask, most of the air goes out the elbow holes because there's less resistance, but nothing blocks air flow going back up the hose.

Nothing blocks the airflow back up the hose? That's what the flapper valve does. I guess we have just about exhausted <g> this subject.

In either case, it is my opinion the original poster need not worry about contaminating herself from the hose. If we could reinfect ourselves, we would never get well.

The following test is different from yours and produces different results. When I put the mask on, without the hose connected to it, and exhale, air comes out of the two large holes in the elbow connection, only. If I hold my finger at the hose connection, I do not feel any discharge of air. All of this occurs because the flapper valve has been forced by my breath against the hose connection, so the only exit for the air is through the two large vents. That's 1).

good luck, I think you're talkin to a brick wall there, arch.

I can explain it for you. I can't understand it for you.

The purpose of the flapper valve is to prevent the patient rebreathing air that has already had some oxygen removed and to prevent unregulated loss of compressed air.
.

so, you're just ignoring the *stated* documentation of every manufacturer out there, that states that the purpose of that valve, which opens to outside air when the flow generator is off, is an anti-asphyxiation valve, to allow you to get fresh air, *when the flow generator is off*?

man, you're thick.

please please stop posting and misleading people with your ignorance.

Yeah, that's making me start to doubt myself.

Those thrush lozenges are horrible, and for me, next to useless.
I repopulated my mouth with used chewing gum previously inoculated by my husband.
Recovery was almost immediate!
I wonder if the good bugs would survive freezing.
(thinking of freezing some of my used gum--just in case)

The lozenges work for me, although they make my GERD worse. My allergist recommended also taking probiotics and brushing my teeth with tree oil toothpaste.

I'm pretty sure that in this case, it's wardmiller that's full of shit, not us
