Pilairo Q CPAP Mask Parts & Replacements

The Fisher & Paykel Pilairo Q is one of the most popular nasal pillow CPAP masks for a reason: it's minimal, quiet, and forgiving of movement during sleep. But like any mask, it only performs as well as its parts. Once the silicone seal starts to lose its cushion or the headgear stretches out, therapy leaks, comfort drops, and pressure delivery suffers. This collection keeps you stocked with the genuine replacement components that restore that out-of-the-box fit.

Two parts do the heavy lifting here. The Pilairo Q Replacement Seal (400HC125) is the AirPillow cushion that sits at your nostrils — a true one-size-fits-all design, so there's no cushion sizing to guess at. Because it's soft silicone in constant contact with skin and oils, it's the part that wears first; most users replace it every couple of weeks to a month for a reliable seal. The Pilairo Q Headgear Combo Pack (400HC328) uses the adjustable Stretchwise design that self-adjusts as you shift position, and it's what keeps the mask stable without over-tightening. Both are single-patient replacement parts, so buying genuine Fisher & Paykel components matters — off-brand fits rarely hold pressure the same way.

Not sure whether the seal or the headgear is your problem? A mask that leaks even after adjusting straps usually needs a fresh seal; a mask that won't stay put or leaves marks points to worn-out or over-stretched headgear. Replacing the right piece is far cheaper than swapping the whole system, and it keeps your prescribed pressure on target night after night.
