Resmed AirSense 10, humidifier discoloring on bottom?

[Jackie1]

Hmm, thanks. Sorry, I meant the 3RD link from my google link.

Pix would help. I've had mine for more than a year, and never had a bit of discoloration.

Here. I usually top off every day with new distilled water.

You should always empty it out every day. I remove tank, empty the water, pull out the seal, turn the seal sideways and leave it between the opening to prop the lid open so it can dry out during the day. With the tank out it lets the seals and hose dry out as well. If you just keep adding water you will grow a culture for sure.

Why?

Not if you clean it weekly. A DROP OF BLEACH will kill 100% of what's in there - including you if you don't rinse the crap out of it after. So if you are confident you can be absolutely sure that you didn't leave an atom of chlorine gas on the thing you will be sucking from, that's the best ferm killer. Not something I would recommend for your average idiot though... Or for people who have someone who is in your will that cleans it for you. Basically, by the time you have difficulty breathing, it's too late. I had that experience once. Different reason, but for about 20 minutes after being extracted from the area by first responder emergency personnel, it became more and more difficult to breathe.

Fortunately, I had my parachute on, so I had the pilot drop the gargo bay door on the c130 at 30,000 feet and I jumped. That is the only way I could get enough fresh air rushing by to suck the deadly gas out of my little plolyampules or whatever they call those little berries in your lungs. Anyway, when I finally landed, I was fine. But my eyes were gobstoppers and my twig and two berries were twisted around each other from the crude military harness.

Bacteria will explode in warm water in 20 minutes. You are not living in a 100% sterile environment, so you are creating the absolute perfect way to grow microbes.

Got any actual evidence to back up your claim? You gave none.

There is water and water. Distilled water will NOT support bacterial growth, since growth for any kind of life requires nutrients, like carbohydrates, fat, or protein - distilled water has none of these. Most tap water is also nearly free of nutrients that will grow bacteria, though not all towns are up to standards.

The water in the air in the hose from your humidifier will have NO bacteria in it because the air comes from evaporation which is the same thing as distillation.

If you drop a sugar cube into your humidifier reservoir it will grow bacteria, sure, because you've provided it with a nice pile of nutrients.

And bacteria are all around you, on you, and inside you all of the time. In fact there are vastly more bacterial cells in your body than there are actual human cells. That's why the human biome has recently become such a hot field for study.

I use distilled water and add more in daily. Once a week I empty the reservoir and put some hydrogen peroxide bleach in it. I have not come down with any dreaded diseases in the year I have been doing this. Of course this is a meaningless anecdote and provides no real useful evidence, just as your claims about bacterial growth in water provide no useful evidence.

Anyone have this issue? Brand new machine, and using only distilled water.

Yes I have a very similar discolouring and I think its from MFG the bottom steel plate to plastic when they used a adhesive maybe to bond the two together. My machine is just over one month old and has never run dry.

There was some test done by a member on here.

As soon as you have cracked the lid on that distilled water jug, you have ceased all possible sterility of it (assuming it was sterile to begin with). Unless your bedroom is sterile, the humidifier tank is sterile, the air is sterile, the hose is sterile and... you get the point. Crap is going to grow in that water if it is not dumped out and changed daily.

You are missing the point, I think. It's not about "sterile" - distilled water, assuming it is truly distilled water, is H2O and H2O only. Bacteria that get on it will find nothing to eat and will soon die of starvation.

Heck the air you breath in isn't "sterile", it's full of bacteria. And if you are truly worried about bacteria never go into your bathroom or use a door handle.

In fact the number one best way to protect yourself from infections is to wash your hands properly in soap and water several times each day. Especially after you've touched another person's hands, or raw food (and not just raw meat).

I have not seen any evidence that the humidified air can carry bacteria to the mask even if the water is polluted. Water that sublimes into the air via evaporation carries no bugs with it, no nothing except molecules of H2O. And of course your mask will be full of bacteria anyway, from your breath and spittle. The manufacturer of my mask nevertheless only recommends weekly washing, not daily.

I haven't read any replies, so take that at will! I hope I am not retreading any information and wasting your time!

Inspect the chamber to see if the discoloration is removable as if some type of build up from the water you are using or cleaning solutions is leaving some sort of residue. If it is not this and it is more a non-removable burn, then call your provider immediately and get the machine exchanged under warranty!
