Strange smell during the day
Hey Everyone!

Just started - about 2 months ago - using a cpap and it's been great…sleep great and feel great.

But Wink

A few weeks after I started I was getting out of my car, it was the middle of the day, and I could smell manure…lol

At least, that's the closest I could come to describing it. Maybe a cross between manure and freshly dug dirt. It was a fairly strong smell so much so that I asked my uncle if he smelt it, if he had any work done at his house and he said no to both.

Now I get that smell quite often. It doesn't last long and it's not as strong as that first time but it's been on and off, usually every day, since then.

I didn't put it together with the possibility of it being the cpap machine because I wasn't smelling anything funky while using the machine - and I've used both the pillows and the nose mask (never tried the full mask) and have settled on the pillows. The smell occurred while using both.

Reading through the forums I've noticed many discussing smells coming from the machine, or during the night, but has anyone had any similar experiences?

Appreciate your thoughts!
ps…I do have an appt. with the doc next week but I'd like to know hear what you all thing as well.

Has Mr. Doggie been sleeping a little too close to your air filter?

Actually, I could imagine a scenario that says with the 8 hour a day air flow into your sinuses your sense of smell could be altered a bit. But I really haven't heard of such a thing.

This smell you describe is a organic, natural smell. The xPAP is all metal and plastic, and any smell it could cause would be more chemical in nature, so it seems unlikely that it could be causing this. Be sure to use fresh, distilled water (at least until you identify where the smell is coming from).

Do you ever get a rainout? If moisture stays in the hose, that can allow mildew and mold to grow. I would assume your Airsense has a heated hose and blows air slowly for an hour or so after shutoff, both to help minimize this. If you have rainout, a hose cozy might help. Once a week, take the hose with you when you take a shower.

When I take off my mask many times I will smell things in the room that I normally would not have except for the fact I've been on the mask with a filter for 6-8 hours. During the winter it was typically a sweet smell that would last a couple of minutes. It would be something near the bed, bedding perhaps the fragrance in the clothes detergent or rinse.

For a couple days it once it was because Febreze had been sprayed on a chair in the room.

The extra smell sense disappears pretty quickly though and I don't get it any other times later.

Hi Trident50,
WELCOME! to the forum.!
It's great to hear you are adjusting well to CPAP.
I haven't had that particular thing happen. Sometimes my husband will think he smell smoke or something burning and there's nothing there, he doesn't use a CPAP.
I've heard that called ulfactory Hallusinations, (sorry for the misspell.)
Hang in there for more responses to your post and much success to you as you continue your CPAP therapy.

Tongue Suck Technique for prevention of mouth breathing:
  • Place your tongue behind your front teeth on the roof of your mouth
  • let your tongue fill the space between the upper molars
  • gently suck to form a light vacuum
Practising during the day can help you to keep it at night

I'm guessing your sense of smell is improving.
My sense of smell is definitely returning. At least in my machine there is a pre-filter and higher efficiency filter. Then the air passing through the humidifier will be further cleaned. I run the Rh as high as I can and likely helps sinuses to purge a little better. All in all I am not surprised this one of the benefits of this therapy.
I use my PAP machine nightly and I feel great!

This was my first thought after only reading the thread title.

As incredulous as that might sound, I think you might have hit on something. I noticed, after a couple of months of XPAP therapy, that I was interpreting smells somewhat differently than I ever had before, something I mentioned here a while back. Maybe this really happens.

That thought was lingering in the back of my mind when I originally replied to this thread, but it did seem, well, incredulous enough for me not to even broach the subject or even begin to know how to phrase it. Now I'm not so sure this isn't something that really happens.
