Quick answer: These are genuine ResMed replacement valves for the Mirage Quattro full face CPAP mask, supplied as a 10-pack (part 61287). Full face masks include an anti-asphyxia valve — a safety component that opens to room air if the device stops delivering airflow, so the wearer can still breathe through the mask. A 10-pack is the practical size for clinics, home-care providers, and anyone keeping spares of this safety part on hand.

- 10 × Mirage Quattro valves (part 61287)
About this part
Because a full face mask covers both the nose and mouth, it includes an anti-asphyxia valve (AAV) as a safety feature. In normal use, airflow from the device holds the valve closed and therapy proceeds as usual. If the airflow stops — a power cut, a disconnected hose, a device fault — the valve opens to room air so the wearer breathes ambient air through the mask rather than rebreathing exhaled gas.
That makes it a component you don't put off replacing. The valve is a thin, flexible membrane flexed with every use and handled during cleaning, so it can tear, stiffen, discolour, or stick over time. It should be replaced if the membrane looks damaged or deformed, doesn't sit flat and move freely, or doesn't close properly during therapy.
A 10-pack keeps this critical safety part in stock — practical for providers managing multiple patients, or anyone who'd rather always have a spare.

Important safety notes
Never remove, block, tape over, or modify the anti-asphyxia valve. It is a safety component. Check it as part of regular cleaning: the membrane should be intact, flat, clean, and free to move. If it is torn, deformed, stiff, discoloured, or sticking, replace it before further use. If you are ever unsure whether a valve is functioning correctly, contact your equipment provider or clinician.
Frequently asked questions
How many valves are in the pack? Ten.
What does the valve do? It's an anti-asphyxia valve. During therapy, airflow holds it closed; if the airflow stops, it opens to room air so the wearer can breathe ambient air through the mask.
Does it include clips? Confirm against the packaging — this may be valves only, whereas the single item (61286) is a valve and clip together. Contact us if you're unsure.
When should it be replaced? If the membrane is torn, deformed, stiff, discoloured, or sticking, or if it doesn't sit flat and move freely.
Can the mask be used without the valve? No — it's a safety component and must be fitted and functioning.
Do I need a prescription? No — replacement mask parts like this do not require a prescription.
Can I get them delivered in Brooklyn or shipped nationwide? Yes — Task Supply Corp offers USPS shipping throughout the continental U.S., plus local pickup and delivery in Brooklyn and all five boroughs of New York City.
This is a safety component. Do not remove, block, or modify the anti-asphyxia valve. Inspect it regularly and replace it if damaged. Use with your ResMed Mirage Quattro mask according to the mask's user guide.
