If you are using a non-vented mask with a single-lumen tube, the Respironics Whisper Swivel II is an absolute necessity. Most CPAP/BiPAP masks require a way to exhaust exhaled air; the whisper swivel exhalation port provides this “leak” path in a controlled, silent manner.
Key Features & Benefits:
- CO2 Clearance: The whisper swivel ii exhalation valve is specifically designed to prevent CO2 rebreathing by providing a continuous flow of exhaust air, which is vital for patient safety.
- Whisper Quiet: True to its name, the internal baffle design reduces the noise of rushing air, ensuring a peaceful sleep for both the patient and their partner.
- 360-Degree Rotation: The whisper valve swivel exhalation for single lumen tube features a full swivel mechanism, preventing tube kinking and allowing for freedom of movement during sleep.
- Universal Fit: Features standard 22mm connectors, making it compatible with a wide range of masks and breathing circuits.
- Easy Maintenance: The whisper swivel ii can be easily disassembled for thorough cleaning and disinfection, ensuring long-term hygiene.
- Durable Construction: Made from high-quality medical-grade polycarbonate, it is built to withstand the constant pressure of whisper valve ventilator use.
Why Use the Whisper Swivel II?
Using a mask without a built-in vent (non-vented) requires an external exhalation port. The Respironics Whisper Swivel II exhalation valve is the most trusted choice for clinicians globally to ensure therapeutic pressure is maintained while safety standards are met.

Frequently Asked Questions (FAQs)
What is the difference between Whisper Swivel and Whisper Swivel II?
The Whisper Swivel II is the upgraded version featuring a more streamlined design and quieter airflow. It provides better CO2 flushing at lower pressures compared to the original model.
Can I use the whisper swivel exhalation port with any mask?
It is primarily used with non-vented masks (masks that do not have holes in them). If your mask already has exhalation holes, adding a whisper swivel valve might cause too much air leak, making the therapy less effective.
How do I clean my whisper swivel ii?
You should clean it daily. Disassemble the swivel by gently pulling the parts apart, wash with warm soapy water, rinse thoroughly, and air dry. Do not use bleach or harsh chemicals as they can crack the plastic.
Why is my whisper swivel exhalation valve making a whistling sound?
A whistling sound usually indicates that the internal parts are not seated correctly or there is a small obstruction/debris in the vent port. Disassemble, clean, and re-seat the parts to resolve the noise.
