  • Brand:Human Design Medical

The Q-Tube reduces sound levels and acoustic noise generated by CPAP/BiPAP machines and tubing. QTube is compact and lightweight so it is ideal for travel and home use; and it is universally compatible with all CPAP/BiPAP machines.


  • Reduces Perceived CPAP Tubing & Machine Noise Up to 90%
  • Lightweight & Compact: Ideal for Travel & Home
  • Universally Compatible with All CPAP/BiPAP Machines
  • Easy to Install & Maintain

Reduces Tubing & Machine Noise: QTube is a unique inline adapter that fits between your CPAP/BiPAP Machine and standard or slimline tubing. A foam baffle inside the QTube reduces sound levels and acoustic noises that can often irritate sleep therapy users and disturb sleep partners. With QTube in place perceived tubing and machine noise, at the mask, can be reduced by 85-90%. It's the ideal accessory for a peaceful night's sleep!

Lightweight & Compact: Ideal for Travel & Home Use: The QTube CPAP/BiPAP Muffler is about 5 inches long and the whole system only weighs about 3 ounces in use! It is easy to attach and detach from your machine and, because QTube sits inline with your standard tubing, it won't add a lot of clutter to your sleep therapy setup.

Universally Compatible with All CPAP/BiPAP Machines: QTube is designed to work with all CPAP/BiPAP machines including those from Human Design Medical, Somnetics, Philips Respironics, ResMed, Fisher & Paykel, Devilbiss Healthcare, and more. QTube can be used with standard tubing, performance tubing and slim tubing; however because QTube needs to attach to your machine at the air outlet port, it cannot be used with most heated tubing systems.

QTube can be used with heated humidifiers as long as the QTube is disassembled each day and allowed to dry out between each use. The QTube device and all parts must always be completely dry prior to use.

Easy to Install & Maintain: QTube attaches to your CPAP/BiPAP machine's outlet port via the included short tube. Together the QTube and short tube provide a lightweight, flexible, adaptive connection that won't kink or pull on your standard CPAP/BiPAP tubing or mask. QTube's foam baffle material should be replaced on a regular basis, usually once every 2 weeks. For full usage and care instructions please review the user manual that came with your QTube.

    This was a repeat order so I was familiar with what to expect. The product arrived as scheduled in a timely manner and was as advertised. I highly recommend this vendor!!!

  • It does nothing.


    I got my QTube yesterday. I've tried it in several places between the cpap and the mask. There is no noise reduction.

    This helps with my small CPAP which is nice; but its still louder than my regular machine.

    This thing is useless. I do not notice any difference in sound. Save your money!

  • works well - BUT


    The QTUBE does its job of silencing the tube noise however if you read the warnings on the package insert they say it needs to be disassembled each night to let the foam dry out.

    I wouldn't have believe it but the Q-Tube really works. I got it free with my Z1 CPAP but my wife said it works so well that I've bought one for my Intellipap as well. Really good invention!
