Quiet comfort
With the quieter System One, everyone can sleep easier.

Everyone benefits from System One's dramatic noise-reduction enhancements. By making our Flex Family of comfort technologies even quieter, patients and their bed partners get a more restful, comfortable night's sleep and may find it easier to comply with sleep apnea treatment. And providers and clinicians may get fewer callbacks and complaints.

Proven results, supported by testing
Some devices seem to be quiet when turned “on” but not connected to a patient. In contrast, our enhancements to System One make it one of the quietest devices on the market when it matters most: when patients are breathing on it.

But don't take our word for it: testing by an independent, third-party laboratory shows that the System One REMstar Auto is quieter than the ResMed S9 AutoSet.*

This graphic shows the results of the noise comparison between the System One REMstar Auto and the ResMed S9 AutoSet devices during lab testing. The difference is clear: System One is quieter. In fact, on average, System One is 25% quieter than the S9 during simulated breathing conditions.

With or without a humidifier, and at varying comfort relief settings, System One outperformed the S9 in an area critical to patient compliance – the ability to operate quietly when in use.
