SoClean is an ozone generator and circulates the ozone through the entire circuit of your gear, from the mask through the hose and then the machine's internal turbine chamber in order to sanitize it, but it leaves dry scum from rain-out in the tube and saliva in the mask, leaving a dry residue behind, which is most likely the flaky white stuff you see blowing out.
Ozone is also known to degrade inorganic compounds like foams, and materials used in insulation, the primary reason behind another company (philips) to make their historic recall of their equipment because they found that the sound abating foam inside their machines breaks down when exposed to ozone. It could be that materials inside your machine are being broken down by SoClean ozone OR somehow external debrie is getting inside of the air circuit which is then blown out, on startup. You may also wish to read up on the US FDA's take on equipment like soClean:
"The FDA performed some testing, and found that the devices claiming to clean CPAP machines and accessories generated unsafe ozone levels in the area (probably because it leaks into the room)"
I clean my machine with pure vinegar, then Dawn dishwash soap, and then a thorough rinse with tap water, followed by a final rinse of demin water. I do not have this issue of white stuff blowing out. Vinegar dissolves any minerals which may build up in the water reservoir.
I only use dawn and since I only use distilled pure water, I don't worry about mineral build up .
By the way medics advise against using tap water in CPAP in order to reduce chances of water solubles and water born pathogens, getting into the lungs.
I don't like buying the distilled water in the wasteful 4 liter plastic containers. Instead I have a couple of 5 gallon water jugs that I fill with Reverse Osmosis water from a local store. Saves me trips to the store, some money, and all those plastic jugs going to recycle, or whatever they do with that stuff. Depending on how often I clean the humidifier I can find some slight residue. When we go on vacation for a couple of weeks we just use tap water, and I have no concerns about that. The humidifier acts like a mini distillation unit, so the minerals stay behind in the reservoir. It takes a bit longer to clean up when we get back, but vinegar does the job. Pure vinegar is also a good disinfectant when used full strength. I would never consider using one of those So-Clean ozone units. Ozone is very aggressive and it is not surprising it would attack foam in a CPAP. I am surprised that Phillips has not sued So-Clean for the damage to their machines and the recall costs they had to pay.
The SoClean commercials are horribly misleading. They make it sound as though the manufacturers are recommending the use of So-Clean, when, in reality, the opposite is true; it invalidates the warranty. I use a cleaning process similar to that described by Sierra, above.
Agreed. I think that Phillips will eventually go after them.
I’d have to check, but I think I saw that SoClean sued Philips, presumably preemptively—possibly as an exercise in forum shopping.
On what grounds would SoClean be able sue Philips? For having machines that SoClean destroyed with their SoClean ozone contraption and caused Philips hundreds of billions worth of damage?:-)
In the first instance, anyone can file a complaint in court about anything. It will then be challenged with a motion to dismiss which may or may not prevail. But in matters where cross litigation is anticipated, and choice of venue may be important, strange things are sometimes done to gain strategic advantage. I haven’t reviewed the pleadings, so don’t know the (alledged) basis for the suit.
I just checked. They sued for defamation Oct 21st, alleging that Philips was making SoClean a scapegoat for their own defective machines.
Hahaha:-) Yes, I remember now.:-) Fact is that Philips has never once used the name SoClean in their findings, but yes they do say "Ozone cleaning equipment" can damage the sound abating foam... So they just have to prove that Ozone does in fact damage the foam (which I imagine they can, very easily and they have the US FDA findings on their side too). Fact is that SoClean's entire net worth is pocket-change in comparison to Philips Respironics, so they must know that they simply don't have the stamina to go the long way in a court battle and be able to prevail. A very ill advised move which will cost SoClean dearly at the end.
