Slow Cooker? [for disinfecting masks or hose]

RE: Slow Cooker?
If you are really worried about it, just fine your equipment a soak in control III. But I agree with the others: you don't need more than a gentle cleaning with soap and water.

The package on my Wisp nasal mask has a temperature maximum of 116 degrees printed right on it. Others may be the same.

It's a filter where one end plugs into the CPAP end of your hose, and the other end plugs into the outlet from the CPAP.  So it goes in between the CPAP and the hose.

I didn't look too closely at what size bacteria or other things it would stop.  If it works the way they seem to imply, then it will keep bugs from the humidifier from getting into the hose and mask.

edit:  Some of the descriptions say they might interfere with auto-adjusting systems because of the way they could interfere with airflow.  Might not be the greatest thing ever after all.

edit x 2: at least one brand said not to use it with a humidifier.

Thanks. I'll investigate.

Of course, if you are so compromised that a CPAP could cause more harm than help, you need to be discussing this with a medical specialist and not some guys on the internets.

Good caveat. My physicians are aware. They also generally trust me to look out for myself as far as keeping my risks minimized. So far, so good.

No wonder my Wisp silicon frame snapped during the historic California heat-wave (that I'm hoping just ended).

The filters are hydrophobic membrane filters which are are very effective for removal of bacteria. They are, however, much more resistant to air flow than fiber filters and, if they become wet, will completely block air flow. They are more expensive than standard filters and need to be changed more frequently because of the small surface area and small pore size. I've had a lot of experience with such filters from small lab scale capsule filters such as those supplied for CPAP use to 10" pleated cartridge filters used to vent purified water tanks. They are generally heated to prevent condensation and blockage of air flow. I would not use them with a humidifier, especially if you have any rainout issues.

If your concerned with bacteria from the tubing, the filter would need to be installed between the tube and the mask.

Thanks  You guys are incredible..... such a wealth of technical knowledge!

I'm thinking the most important thing for me is to keep the parts clean every day. Then, if there are issues, to go with something more dramatic. I liked my $10 slow cooker concept, because it's cheap, programmable, and do-able (it sure would be the ozone machine), but it sounds like I might have to abandon that idea.

What about wearing a surgical mask of some sort, underneath the CPAP mask?

Don't know how well this would work, how well it would seal or how much airflow it would block.

If the problem is potentially so serious, though, what about not using the humidifier at all (so you won't have to worry about whatever might be growing in the humid environment) and just go with the ultra-fine filter on the air intake side of the machine?

You say you wash your hands 50 times a day, wash your mask with whatever you wash your hands with and you shouldn't be any worse off.
