Frequently asked questions about ResMed AirFit F40 Full Face CPAP Mask
How is F40 different from F20?
F40 uses an under-the-nose minimal-contact cushion, while F20 seals around the nose and mouth with a traditional full-face cushion.
Is F40 suitable for side sleepers?
Its compact frame and flexible short tube are designed to accommodate movement, but individual fit and pillow contact still matter.
Can I use F40 with BiPAP?
It uses a standard PAP connection and can be used with compatible CPAP/BiPAP therapy when the mask seals at the prescribed pressure.
What about pacemakers or implants?
F40 uses magnetic clips. Follow ResMed’s current contraindications and magnet-distance warning for affected implants.
