ThermoSmart AirSpiral Heated Breathing Tube for F&P SleepStyle & SleepStyle+

Genuine replacement ThermoSmart AirSpiral Heated Breathing Tube for the Fisher & Paykel SleepStyle and SleepStyle+ Auto CPAP machines. Required to activate the full ThermoSmart™ humidification system — and 20% lighter than F&P's previous heated tube design.

Key Features

• AirSpiral technology — a dual-spiral design combines an insulating spiral and a heating spiral that work in tandem to maintain tube temperature, minimising condensation and heat loss from humidifier to mask
• Eliminates rainout — by keeping the air warm throughout the full length of the tube, the AirSpiral design prevents the condensation that causes water pooling, gurgling, and sudden cold moisture in the mask
• 20% lighter than the previous ThermoSmart tube — the reduced weight lessens drag and pull on your mask during sleep, improving positional stability and reducing the chance of mask displacement
• Activates ThermoSmart humidification — the tube's integrated connector communicates with the SleepStyle device to enable the full heated and humidified therapy experience; a standard tube alone cannot replicate this
• Hard plastic connector ends — provides a consistently firm, secure connection to both the machine and your mask elbow, reducing accidental disconnection during sleep
• Standard 1.8m length, 22mm diameter — compatible with the full range of standard CPAP masks
• Not made with natural rubber latex — suitable for users with latex sensitivities

Who Is This For?

This tube is the right purchase in two situations. First, if you own a Fisher & Paykel SleepStyle+ Auto CPAP Machine and your existing heated tube has worn, cracked, or been lost — a replacement is needed to restore full humidification performance. Second, if you currently use a standard breathing tube with your SleepStyle machine and are experiencing rainout, dry mouth, or inconsistent humidity throughout the night, switching to the ThermoSmart AirSpiral tube is the most effective fix. The SleepStyle's humidification system is designed to work in partnership with this tube — without it, the machine cannot maintain consistent temperature along the full air path, which is where condensation forms. Heated CPAP tubes are generally replaced every 12 months or sooner if the tube shows visible wear, discolouration, or a loss of connection integrity. Note: this tube is compatible exclusively with the SleepStyle and SleepStyle+ machines. It will not function correctly with CPAP devices from other manufacturers.
