Fisher & Paykel SleepStyle Air Filter, 2-Pack

The Fisher and Paykel SleepStyle air filter mounts at the rear of the machine, in the path of the room air the device pulls in before pressurizing it. It is a disposable part, pinched out and pushed back in by hand, with no tools involved.

Fisher and Paykel rates this filter for about three months, or roughly a thousand hours, of nightly use before it should be swapped out. This listing ships two filters, enough to cover half a year before reordering.

Key Features:

• Rear-mounted filter: Mounted behind the machine's housing, catching dust and pollen from room air before it is pressurized.
• Disposable, not reusable: This filter is thrown away once it has done its three months of work, never put back in a second time.
• Three month cadence: Fisher and Paykel rates it for about three months, or roughly a thousand hours, of nightly use.
• Pinch and pull swap: The old filter pinches out by hand and a new one pushes back in, with no tools needed.
• Pack of two: Two filters ship in this listing, enough to cover roughly six months before a reorder is needed.
• SleepStyle Auto CPAP only: Sized for the SleepStyle Auto CPAP series specifically, and not for other Fisher and Paykel machines.

A filter that looks gray or has gone past its three months is doing less to protect the machine's blower than it should, since restricted airflow at the intake can affect the pressure the device delivers. The swap itself takes only seconds.

Note: This filter fits the Fisher and Paykel SleepStyle Auto CPAP series only, not other Fisher and Paykel machines or other brands entirely.

Where this filter sits

Room air enters the SleepStyle machine at the rear, passing through this filter before it reaches the blower and the pressurized side of the system.

A blocked or heavily loaded filter at that point can make the machine work harder to deliver the same set pressure, which is the practical reason to keep it current.

Replacing it on schedule

Fisher and Paykel publishes a three month, roughly one thousand hour, interval for this filter, whichever mark is reached first during normal nightly use.

A filter that looks visibly gray or discolored ahead of that interval is worth swapping early, since appearance is a reasonably reliable sign of how loaded it has become.

A simple, tool-free swap

The filter sits in a small compartment behind the housing, held by friction rather than a latch or a screw.

Pinching it between two fingers and pulling releases it, and the replacement seats the same way, pushed in until it sits flush with the housing.

Here's everything that comes in the box.
