Is that an unprecedented JohnBFisher stereotype? However, John, I think your point is very well taken: irrational anxiety about BPA in our CPAP machines probably stands to affect people more than the chemical exposure itself. That's not the first time this message board has discussed irrational BPA fears either: viewtopic.php?f=1&t=34026&p=300042&hili ... ng#p300042.JohnBFisher wrote: You know the type.
However, as BlackSpinner well pointed out, the real scientific concern over BPA has more to do with suspected subsequent-generation epigenetic issues rather than first-hand BPA exposure-related adversity. If I had infants I would probably feed them from glass bottles rather than plastic. If I was going to cast my genetic seed to future offspring, then I would probably minimize my exposure to BPA. It's a personal choice based on how I happen to interpret the ongoing scientific research. I tend to place more stock in what many independent scientists currently think than I place in chemical-industry damage control campaigns. I think Trevor Butterworth linked above is doing a fine job of representing the interests of the chemical manufacturers.
I'll also point out that since that older BPA thread I have linked above, I have personally gone from using no humidification whatsoever, to using heated humidification with my RemStar plastic chamber. Why did I use no CPAP humidity for so many years? Because I find humidity to be initially very uncomfortable. So why did I go back to using heated humidity after those old BPA discussions? Because the last two years I have suffered prolonged bronchitis/infection type problems without the humidity. I perceive that as a faaaaar worse health risk than ANY incidental BPA exposure I might encounter using my CPAP humidifier.
