This product is the same quality item that comes as standard with virtually all CPAP and bilevel machines. It is two feet longer, allowing the user more freedom to move around during sleep. The additional length does not cause a significant decrease in CPAP airway pressure.

All brand hoses are smooth bore designed. Smooth bores have no ridges inside the hose for air pressure to resist against. The supportive wire frame is located on the outside of the hose. This design provides consistent pressure delivery and ensures a quieter performing hose.
