While the amount of sound a CPAP makes is not the only concern it is probably one of the most important. If your CPAP is too loud, then you probably will not sleep well. In this blog we compare each Travel CPAP model on a decibel meter. All of them were set exactly the same at 10cm with the same setup.   In our comparison we ran the ResMed AirMini, the Transcend Micro, and the Breas Z2 on a decibel meter. Each of them were hooked up with 6ft slim style CPAP tubes and attached to a ResMed N20 nasal mask. The Micro and the Z2 both were connected with their tubing muffler which are included. The AirMini was hooked up with it’s own proprietary tube. The findings are listed below.

Transcend Micro Travel CPAP sound levels:

The Transcend Micro fluctuated between about 46-55 decibels when running at a setting of 10cm. On inhalation the sound was about 55 decibels and on exhalation is backed off to around 46. We did use the Transcend tubing muffler in line to give the lowest sound that we could.

Breas Z2 Travel CPAP sound levels:

The Breas Z2 was a bit more stable from inhalation to exhalation and ranged from about 55-60 decibels. This unit was also set at a pressure of 10cm and attached to me with an N20 Nasal Mask. We also used the Q-lite tube muffler on the Z2 to have the lowest sound possible.

ResMed AirMini Travel CPAP sound levels:

The AirMini was the quietest in our comparison. On inhalation it topped out at around 51 decibels, and on exhalation it dropped to about 42. This was also hooked up to the N20 Nasal mask at 10cm using the AirMini N20 adapter.
