Overview
This heated tube carries warm, humidified air from your DreamStation 2 to your mask. It's Philips' smallest-diameter tubing, so it takes up less space on the bed while helping the humidity you chose arrive intact.
It fits the DreamStation 2 CPAP and Auto CPAP, including the Advanced models. This is Philips part HT12, the micro-flexible heated tube, and your DreamStation 2 recognises it the moment it's connected.
Key features:
- Smallest Philips tubing: Its narrow profile is designed to stay comfortable while leaving more of the bed free around your pillow.
- Five warmth levels: Choose off or one of five levels on the therapy screen, and your pick carries over to the nights that follow.
- Clip-on connector: Pin contacts and side clips lock it onto the DreamStation 2 outlet with a click you can feel.
- No tube setup: The machine detects the heated tube and its size on its own, so there's no tube type to pick.
- Keeps therapy going: If the tube develops a fault, the machine shows an alert and carries on with therapy without heating the tube.
- Temperature limit: Philips builds in a temperature cut-out for the heated tube, so the heat switches off if the tube runs too hot.
It suits DreamStation 2 users who want warm, humidified air at the mask from a hose that takes up as little room as possible. If you're on the original DreamStation, the 15 mm heated tube is the one Philips made for your humidifier.
Note: Made for DreamStation 2. The original DreamStation uses the 15 mm HT15 heated tube, and Philips' unheated 12 mm PR12 is a different part, so check for HT12 on the cuff.
How it works
Attaching the tube
Bring the tube's pin connectors to the lower edge of the machine's outlet, with a clip facing each side. Press until the clips click into place, then connect the mask end to your mask.
Choosing a level
During therapy, tap the heated tube icon and choose Off or 1 to 5, where 1 is the coolest. If an alert says there may be a problem with the tube, turn the device off, check the tube isn't covered, and reattach it.
Washing and replacing
Disconnect the tube and wash it in a solution of 5 mL mild liquid dish soap to 3.8 L of warm water, agitating for one minute. Rinse for a minute and air dry fully before use. Philips sets a limit of 26 washes and a 6-month replacement.

Everything you need to know about the Philips DreamStation 2 Micro-Flexible Heated Tube
Humidity held at the mask
The DreamStation 2 humidifier and this tube work as a pair. Warming the air as it travels helps maintain a comfortable humidity at the mask, so more of the moisture you pick on the screen reaches you.
Less hose on the bed
A thick hose can crowd the pillow and catch as you turn over. Philips designed its smallest-diameter tube to be comfortable while taking up less space, which leaves more of the bed free around you through the night.
Tube temperature from the screen
Tap the tube icon on the therapy screen to choose off or one of five levels, and the change applies straight away. If the tube ever develops a fault, therapy keeps running without the heat while you sort it out.

Philips' slimmest tube
This is Philips' smallest-diameter tubing, so there's less hose to manage around your pillow at night.
Adjustable warmth
Tube warmth has its own control on the DreamStation 2 screen, and you can change it while therapy is running.
Clips into place
Pins line up with the outlet and the side clips click home, so you know the tube is properly connected.
Detected automatically
Your DreamStation 2 recognises the heated tube when it's attached and skips the tube size question during setup.
Frequently Asked Questions
Will this fit my DreamStation 2?
It fits the DreamStation 2 CPAP and Auto CPAP, Advanced models included. The original DreamStation takes the 15 mm heated tube instead, and Philips' DreamStation Go manual lists no heated tube at all.
How is this different from the PR12 tube?
PR12 is Philips' unheated micro-flexible tube, and it needs a separate device adapter at the machine. This one, marked HT12 on the cuff, heats the air and clips straight onto the DreamStation 2.
How should I wash the HT12 tube?
Once a week, Philips says to swish it by hand through warm water with a little mild dish soap, then rinse it and let it dry in the air. It's rated for up to 26 washes.
When does the DreamStation 2 tube need replacing?
Philips' DreamStation 2 manual puts the tube's replacement at every 6 months, which lines up with its weekly washing limit. Replace it sooner if it's cracked, torn or punctured.
Does my DreamStation 2 need a heated tube?
No. Philips calls it optional, and the built-in humidifier works with a standard tube. The heated tube adds its own warmth control, which helps keep humidity comfortable by the time it reaches your mask.
