After a week using Eclipse and trying to identify and control these leaks I've come to the same conclusion. I had issues with the Dream Ports leaking too. But that mostly had to do with problems with the clips not properly clicking into place as they got older. I thought Eclipse might have the potential for virtually 0 leaks. But after about 7 nights of experience I can report that fairly reliably around the 4th hour I experience hissing that is loud enough to wake me up. Sometimes it will temporarily resolve if I roll onto my other side. But it will start again if I roll back over on the original side. Sometimes it will start on the other side too. At first I thought I must not have cleaned my skin properly or aligned the adhesive pieces on my nares correctly. But I've had a lot of experience doing these things with the Dream Ports. I think I'm pretty good at it unless something changed in Eclipse. The adhesive does feel a little different (?). It feels like the air is coming out where the metal rings are embedded in the bandaid-like material that adheres to the skin , _not_ between the skin and the adhesive (which would be the usual suspect). Another possible clue: When I attach the magnetic connectors it pulls on the rings at the outside of each nostril since my nares do not quite point straight down. Attaching the magnets forces the hose connectors to point downwards and be parallel, pulling on the nostrils slightly and causing them to flare out. That's not a problem in terms of comfort, and it may help open up the passage through the nose. But it does cause constant tension between the metal rings and what I'm calling the bandaid-like material they're embedded in. This is where I think the leak is happening. Another possible complicating factor is that my nostril openings are somewhat long and narrow rather than perfectly round. Hopefully there is a quick fix. I tried sealing up that area with pieces of cover roll tape (which I also use to tape my mouth), but it didn't work. A longer term solution might be metal rings that are smaller in diameter that would fit more easily side-by-side under the nostrils, introducing less tension on the outside. Or perhaps there could be alternate-shaped rings for those who have narrow nostrils.

For anyone reading this, I reached out to Support and they're going to send me a prepaid box to return the remaining halos. I'm guessing there might be an issue with early lots, but don't know.

While I'm waiting for replacements, I found a workaround. The trick is to get the metal rings as close together as possible. This is critical if you have nostrils that are narrow and/or don't point straight down. When you click the magnetic ports in place it forces your nostrils to point down, putting strain on the metal rings at the outside edges (away from the septum). That's where they were separating from the bandaid-like material they're embedded in, causing a small (but loud) leak. Per photo, you can almost abut the rings in the middle if you turn that bit of adhesive up on both sides and let them stick together (rather than trimming it). Now there is less strain on the outside of the rings when you click the ports in place. [SideBySideEclipsePorts](//muut.com/u/bleep1/s3/:bleep1:QoRz:sidebysideeclipseports.jpg.jpg)

The day after my previous note, I opened a new box of halos (with a different lot #). My leak rate, as reported by OSCAR has been 0, so it may have been a quality control issue. BUT Eclipse is much more noisy than the dreamports!!! I have not been able to nail it down!! Sometimes I go to sleep sounding like darth vader, then wake up during the night to no noise coming from halos. Sometimes the other way around. Twice I’ve woken up to load hissing, but I couldn’t find anything obvious and OSCAR didn’t report any leaks(?!?!). I will keep playing with it until my quarterly supply is used up but I’m debating whether or not to switch back to dreamports. I will definitely keep some halos around for traveling, but while I LOVE eclipse in principle, I have yet to see their benefit in practical use!

If you go to time index 15:15 in Jason Sazama's YouTube review https://youtu.be/-GTbB0cO5P4 he mentions more pronounced breathing noise with Eclipse. At first I noticed this too, but now I'm used to it. I don't know if it's related to the issue of the metal rings partially separating during the night, causing an actual leak (not just noise). I would not think the two things are related, although subjectively I have noticed that the breathing-associated noise seems louder as I'm going to sleep on nights where the ring ultimately separates slightly and leaks. Curiously, as you reported, sometimes I hear no breathing noise at all, which seems odd. Wouldn't it be consistent once everything is in place? To sum up: I think the "breathing noise" might be different than any actual leaks. It would be nice if Bleep can find a way to mitigate it, but it's probably not a show-stopper for most people. Regarding "loud hissing", if it's the same as I'm experiencing, that's coming from the metal rings eventually getting slightly detached from the bandaid-like material they're embedd ed in. For me it happens at the outside edge of each nostril, where there is the most tension once the magnetic ports are clicked in place. It could be more likely with nares that point slightly to each side, or if the skin between the nostrils (columella) hangs down lower. It might be mitigated somewhat by getting the rings as close to each other as possible. I'm hoping the newer run of Halos won't exhibit the issue when I receive them from Support. But I'm a little concerned because the rings would need to be embedded very securely to get through a whole night, especially for someone who switches sides several times during the night.

So I have the same issue with the loud noise coming from the Eclipse. It appears to be where the filters are on the bottom. If I lightly press on one the sound goes away. So not sure if the filter does not fit right or what. But another thing I noticed is that it typically is the left side filter...but the other night it started on the left and then I woke up at some point and it was now on the right. So again like you said not sure what is causing it.

Do you think your issue could be the same as @elwoodpdowd mentioned when he started this thread...? >How do you prevent halo rings from detaching from adhesive pad? I don't know if this will help show it, but I marked up one of their [marketing photos](//muut.com/u/bleep1/s1/:bleep1:eeS0:bleepeclipsefiltervshaloring.png.jpg) with two arrows. It seems you are reporting air noise coming from the *filter* on the interface. But I'm getting it where the *metal rings* are embedded in the disposable Halos. Once the adhesive pad is folded onto the side of my nostril it forms an angle roughly where the ring is embedded, putting strain on the adhesive holding the pad to the ring. At some point during the night I start to hear a hissing sound (not related to breathing). If I run my finger along that edge at the side of my nostril I can feel air leaking out. It's not a lot, but enough to make noise even at a pressure of 8. Support sent me a more recent manufacturing run of Halos that I will try tonight...

Well tonight I am going to try add some extra filter material to the ports to see if that helps. So yours is around the metal rings...that is odd. I wonder if they had a batch issue in the manufacturer process. I have notice that some of mine are sticky on the side that should not be sticky. I wonder if that is why they put in the "tissue paper" in between them when they ship them as there is a bit of an issue with the application of the glue

I'm also having leakage where the metal ring separates from the adhesive. Happens every couple nights and wakes me up. The first month or so was fine, so maybe I got into a bad batch of the halos.

Any luck?

So the 2 of the 3 past nights I had leak around the metal ring. It was always on the same nostril. I tried putting them on in reverse order and it leaked. So I thought about what had I been doing differently since they are all the same batch number and I have already gone through 3 boxes (ordered a 3 month supply). What I came up with was how I was taking them off the “paper”. I had found it easier to peal them off starting at the most narrow end. In the past I pulled them off by starting to peel them away directly below the metal ring. So I went back to peeling them off the paper by starting below the metal ring last night. Last night I did not have any leaks around the metal ring. So these came off the same sheet of paper that I had leaks around the metal ring the previous two nights.

Another thing I noticed. If you look at the older style the ports are angled. I assume this is so you can turn them to get them coming off your nose fairly straight. When you put on the new ones there is no ability to angle them and the magnetic connectors are only very slightly angled. I think it is the lack of an angle that is pulling on the adhesive. Where to yours leak at? Mine were leaking on the outside edge or the edge farthest to the Left or Right depending on which one. Basically the side that has to be pulled out flat to connect with the magnet the most. So it has the most force applied for most of the night. Mine don't start off leaking (when they do). It is sometime later in the night. It is like sleeping with your mouth open in that it dries things out a lot.

My experience is the same. I think some people's nares point outward to either side more than others. Or, even if their nares point straight down, the columella in the middle hangs down, effectively causing anything attached in a circle around the nostril openings to point outwards to either side. I think the latter is quite common. As you reported, when I attach the magnetic interface to the Halo rings it forces my nostril openings to align and point downward. This also has the effect of bulging the nostrils out slightly (which could be a good thing to improve airflow). But it means the outer edge of the halo rings is under constant tension. So the adhesive attaching the ring itself to the pad material really has to be very strong to overcome this, especially as the night wears on. I'm guessing every time I roll over it is stressed even more. If you scroll through the photos & diagrams in this article you can see that nares & columella vary quite a bit. It's d efinitely an engineering challenge: https://onlinelibrary.wiley.com/doi/10.1002/ajmg.a.32600 PS: I haven't had a chance to report on the new lot of Halos I was sent (#00460). I'll post here in the next week or two.

My niece had the same situation. And it made her sleep worse. At first, she thought it was normal and would be fixed automatically. But it didn't. So she decided to fix it. But that was a failure too. She contacted many people who provides the best medical and lab supplies. They recommended her a new one. The new one is okay and is not a troublemaker. https://www.bndinc.com/medical-and-lab-supplies/
