I'm using the term "bacteria" here but think "microbes," which includes bacteria, viruses, spores, etc.
Bacteria are everywhere.
* Bacteria can get through the air filter.
* Bacteria can get into the port of the machine when you disconnect the humidifier or though the humidifier connection.
* Bacteria can get into the water chamber of the humidifier when you add water or while you are removing, transporting, or putting it back into the machine.
* Bacteria from the air can get into the water chamber through the hose connect any time the hose is disconnected from it.
* Bacteria can travel down from the hose into the water chamber or up from the hose into your nose/mouth.
* Bacteria can travel from the mask into the hose, breed and mutate there for a while, and then travel into your mask again or into the humidifier.
* In fact, microbes from any of these pathways can park somewhere to breed and mutate, then travel eventually to your mouth/nose/lungs.
* In summary, any place in the system where air could reach, microbes can and will be there. The question is, are you creating a hostile environment or a welcoming environment for them?
Distilled water is distilled, not sterile. It comes with microbes whether you buy it in the store or brew your own. Unless you seal something air-tight, you should expect to get microbes in it. Although it can be a problem in the dry parts of the system, it is far more likely to be an issue where there is humidity. Even if you don't use a humidifier, your own breath is adding humidity to the equipment.
The fact that many of you have never noticed a problem doesn't mean there aren't microbes there, it means you've never noticed them.
To date.
