Breas Medical has discontinued the Z Sleep Travel CPAP line (Z1, Z2, Z1 Auto, and Z2 Auto devices), PowerShell, and Q-tube. Nitelog will still be supported.
Service Parts & Patient Accessories: Available for purchase through October 2030.
Warranty & Service: Remain unchanged according to the current Breas warranty policy.
For more information please contact supportUS@breas.com.
The Qtube Replacement Kit contains the replacement foam, O ring and plastic wrap for the Qtube In-Line Muffler. We recommend that these parts be replaced after 14 days of continuous use.
Note: The Q-Lite has replaced the original Qtube. It serves the same function but is 60% lighter. If you own a Q-Lite, you cannot replace the interior foam, so you do not need this replacement kit.
