ResMed AirFit F20 (not mem foam)

[ejbpesca]

After years with the AirFit F10 I tried the Airfit F20 last night.  It fitted well, sealed well and was comfortable.  For the first time in over 10 years of therapy, and trying out 4 other masks, I was wakened within 3 hours due to skin irritation from the mask.  Looking in the mirror showed a ring of red rash where the mask touched and facial swelling.  I wonder if that model has latex or any other property that may be prone to an allergic reaction.  

I think the F10s are silicone.  The cushion of the F20s feel like a different substance.

I have never looked at the returns/refund policy of my supplier.  I'm asking for it now. 

Anyone else experience such a rash situation?

I know this post is about 9 months old I have just seen it ..
Did You wash the mask before use ?? I wonder if it may have had some mold release residue left on it that caused
Your reaction ..
I have been using a F20 for about 8 months with no problems .. But I was told to wash it before use ..
I hope Your having better luck with masks !!

I probably did not wash the new mask.  Since the post, I tried F20s again and now use them with no rash occurring.  Your suggestion could be spot on.  Thanks.
