You have corrosion/oxidation on the power port.Common Get some 99.9% Isopropyl alcohol, sqirt it in the hole you put the plug into on the CPAP, and use a stuff nylon brush to scrub around in the opening. Do this 2-3 times waiting about a minute each time to let the IPA evaporate. Insect the port to...

Bumping this post as I'm having this exact same issue. I'm on my second Medistrom cable now. Any progress or ideas? Last night, myAir reported I had 10 'Mask Off' events. When I checked this on OSCAR, I indeed had 10 periods of sleep reported. it seems to indicate that the machine cut out and reboot...

I've found the F40 not so good at handling high pressure. I got farty leaks at 15cmH2O. The weak spot (for me) seems to be between upper lip and nostrils, despite cleaning cushion and face thoroughly. I resolved this by applying silicone tape strips to my face where it leaks. That provided a great s...

Depends what you read and who you listen to I guess. Lets listen to a peer-reviewed study. https://pmc.ncbi.nlm.nih.gov/articles/PMC10867908/ That's a very interesting study and puts things into perspective. It's very easy to get caught up in the 'must clean' narrative and like I said, I never used...

I wash the cushion and my face every night to help with the seal, I have run 'mask fit' a couple of times and thought I'd got it right, but it's still leaking. How are you washing it? Try washing less, maybe just an occasional wipe with a baby wipe. Cleaning too often is one of the biggest factors ...

Often those "farty" leaks during the night are from moisture that builds up on your face. Try removing or pulling the mask away from your face and wiping the cushion and your face with a tissue or cloth before replacing it. This is common with lots of masks with silicone cushions. Thank you for res...

I love the F40 mask, but disappointed that the cushion has developed leaks this past 3 nights after less than 2 months use. It's the farty leaks that you just can't adjust out and to me, it's an indicator that the cushion has deteriorated and needs replacing. I wash the cushion and my face every nig...

Thanks again, that's good to know I'm not going to suddenly combust in my sleep

I shall likely buy a 2 metre one, which will cover most of the heated tube and all of the F40 extender.

Thanks Pugsy,

Rather expensive as it doubles in price with UK shipping.
Is it ok to use covers on ResMed heated tubes, or will they overheat? I could just buy a long one.

I've never used tube covers as I have a heated tube. However, since I started using the AirFit F40 recently, I'm occasionally getting a little rainout. Condensation is forming in the short tube supplied with the mask, now that the outside temperature is dropping. Is there a short tube cover availabl...

Search Amazon for resmed filter cover adapter airsense 2097 bayonet I see them for both the 10 and 11 machines. As for filter restriction. These filters have much more surface area than the standard filter so less airflow resistance. In any case the machine compensates for any sort of restriction, ...

In theory this looks great! IF you're concerned about the stock filter being inadequate that is. In practice? It all depends on the quality and implementation of this design. These seems to be rather pricy. If I'm reading it right, three filters for $55? Including the 'adapter'? Yikes! The refills ...

I use an adapter on my Resmed 10 machines that lets you use 2097 Bayonet Filters. These are respirator filters, the most common one being P100 particle filters. They are very inexpensive and have a huge filter area. They are ugly, but very effective. The standard Resmed filters aren't great, and mo...

What do we all think of this machine filter door modification? It looks like a really neat solution, but is there a problem to solve? ResMed do supply a hypoallergenic filter, but would that be as effective as this HEPA? The manufacturer does point out that it is not FDA approved, nor endorsed by Re...

Thanks for finding, but I think that's an old document as I can't see any ff mask newer than F10.

It's interesting though.
