Fisher & Paykel SleepStyle ThermoSmart Heated Tube

The ThermoSmart breathing tube is the heated hose for the Fisher and Paykel SleepStyle, and it is the part that turns ThermoSmart on. The manufacturer is explicit that the feature needs this tube connected, so without it the machine does not offer heated humidification at all.

The angled elbow seats into the SleepStyle air outlet and clicks its electrical connectors firmly into place. At the other end sits a plain 22 mm conical connector, which meets the swivel on a standard mask without needing any adapter at all in between.

Key Features:

• Turns ThermoSmart on: Fisher and Paykel state that the ThermoSmart tube is what activates ThermoSmart on the machine.
• More moisture delivered: The manufacturer measures over 18 mg per liter here against over 15 through the plain tube.
• Higher at every level: The gap holds across the range, from level two upward, narrowing only at the very lowest setting.
• Elbow at the machine: The angled end carries the electrical connectors and is the part you hold when turning the tube.
• 22 mm mask end: Fisher and Paykel list it as fitting a 22 mm conical connector, the standard mask fitting.
• SleepStyle only: The manufacturer asks that its breathing tubes not be used with any device other than the SleepStyle.

Order this if you own a SleepStyle and want the humidification the machine was built around. Order the plain breathing tube instead only if you have decided you would rather run without ThermoSmart, since it is sold as its own part.

Note: This is the ThermoSmart tube, not the standard breathing tube. Fisher and Paykel sell that one separately under its own part number, and it has no heating element in it.
