Black mold is more difficult to clean and kill.palerider wrote:bleach is cheaper and works better.SewTired wrote:If it is just on the tank, then replace the tank. You can't really get mold out of plastic very well (some would choose to ignore this advice-their option). If its in the humidifier, then you need to not only replace the tank, but use a disinfectant to eliminate any mold in the humidifier unit (carefully). Our sponsor has a 2 oz. size bottle of the disinfectant which is plenty and it works well.
and "get mold out of plastic" ... please provide credible sources for your opinion.
Antibacterial what so ever is for bacteria not fungi.
A cold/flu/virus is viral again forget about viruses.
Your main concern should be to kill it and certainly to remove (kill) the source. see black spinner.
In the lab we use an autoclave to kill fungal spores. (120°C, pressure high enough that water does not boil, for about 1 h)
For difficult fungal spores we do 2 cycle of autoclave, the first cycle will induce germination of the spore, leave it at room temp over night and re-autoclave to kill the germinated fungi.
You do not need an autoclave, a pressure cooker will do just fine.
Make sure the plastic of the water container can support such high temperatures.
Important is to get the spores to germinate as then they are much easier to kill.
I would suggest to put the water tank into boiling water in a pressure cooker close it and keep cooking for 20 minutes that should be long enough to wake up spores for germination. Then leave the tank at room temp for one night, allow germination to take place. Then repeat the procedure.
If you have black mold in the CPAP I would ask for help from the manufacturer. As last resources I would remove the filter, some how plug the end of the hose so that the air is blown through slowly, hope that can be done, then boil water separately and send the steam through the machine for about 20 min. Ask the manufacturer if that can be done. let it stand over night and repeat it.
This sad bleach is working fine for many molds. It is only problematic for some spores as they are very resistant to all sorts of harsh environment.
You may want to contact a mold specialist to eradicate the mold in the house.
