Hi Steve, we're sorry to hear about the fit issues. Please contact us directly so we can assist you with a suitable solution. Your comfort is important to us!Thank you very much for taking the time to share your detailed feedback.

We’re genuinely sorry to hear that you experienced difficulties with the fit of the mask and that the frame and cushion kept separating. We also understand how frustrating it must have been to order a second Large size and still find the cushion smaller and less comfortable than you were expecting.

Mask fit and comfort are particularly important with CPAP therapy, and we appreciate that an uncomfortable or poorly fitting mask can make using your equipment much more difficult. While the Replacement Set for ResMed AirFit F20 is designed to provide a secure and comfortable fit, individual sizing and fit can vary depending on facial shape and personal preference.

If you’re still experiencing issues with the fit or the cushion separating from the frame, our team would be happy to help with some fit and adjustment troubleshooting to see if we can improve the comfort and seal.

We’re sorry that the replacement set did not meet your expectations, and we truly appreciate you bringing these concerns to our attention. Your feedback is valuable to us.
