Philips ComfortGel Blue CPAP Cushions & Flaps

If your ComfortGel Blue nasal mask has started leaking, marking your face, or simply lost the soft seal it once had, the cushion is almost always the culprit — not the whole mask. Silicone gel breaks down with nightly use, oils, and cleaning, and most CPAP users replace the cushion every few months to keep therapy comfortable and pressure delivery consistent.

This collection carries the genuine Philips Respironics ComfortGel Blue flap & gel cushion replacements in all four sizes, so you can restore your existing mask frame instead of buying a new one:

• Petite (1070108) and Small (1070107) for narrower nasal bridges and smaller faces
• Medium (1070106), the most commonly fitted size
• Large (1070105) for wider nose profiles

The dual-layer design is what makes this cushion distinctive: a soft gel base for stability against the skin, paired with an air-filled outer flap that adapts to the contours of your nose as pressure changes. Together they give a forgiving, low-leak seal that many side and back sleepers prefer over stiffer silicone-only cushions.

A quick sizing note — CPAP mask sizes are not the same as clothing sizes. If you already know your ComfortGel Blue size, match it exactly; if you're between sizes or unsure, the size printed on your current cushion or your original fitting card is the most reliable guide. These parts fit the ComfortGel Blue nasal frame specifically and are not interchangeable with full-face or older ComfortGel Original cushions.

Replacing the cushion on schedule protects both your comfort and the integrity of your prescribed pressure. For related supplies, explore our full CPAP selection, including masks and replacement headgear to keep your setup performing as intended.
