Humidifier Pressure Valve

The Humidifier Pressure Valve is designed to help prevent water or oxygen from flowing into a CPAP or BiPAP machine from the hose or humidifier. When the machine is turned on the air flow passes through the valve from the machine to the air pathway. When the machine is turned off the Pressure Valve prevents oxygen or water from flowing back into the machine.

The Pressure Valve is compatible with any CPAP or BiPAP machine being used without a humidifier, or if the machine is being used with a stand alone humidifier. It's an added defense against costly damage that can sometimes happen when a CPAP unit is exposed to water.

This product includes the Humidifier Pressure Valve alone, and does not come with any other parts or accessories.

What's Included:

  • Humidifier Pressure Valve

Learn More About This Product

The Pressure Valve attaches directly to the machine and allows a stand alone humidifier or long CPAP hose to attach to it. The valve is trouble free and keeps water or added oxygen out of the machine.

NOTE: The valve MUST be installed directly onto the machine to prevent the flow of water or oxygen back into the machine.

Check with respiratory therapist

Verified purchase | Sep. 04, 2022 | Verified CPAP.com Customer
I was using this to prevent backflow of my oxygen when the CPAP wasn't running but was told to stop using it by my respiratory therapist. He said the spring action can confuse the adaptive pressure the cpap is trying to achieve. I am using a ResMed AirSense 10 programmed for a range of pressures. If your prescription is for a fixed pressure it may be fine. Check with your respiratory therapist.

Too Pricey

20 bucks for a piece of molded plastic seems a little much.

PRESSURE VALVE

Verified purchase | Feb. 19, 2008 | Verified CPAP.com Customer
THIS VALVE IS NOT A VERY USEFULL ITEM. I HAVE A CPAP-AUTO A-FLEX MACHINE. THIS VALVE STOPS ITS AUTOMATIC START ONCE WE REMOVE THE FACE MASK. WE HAVE TO START THE MACHINE AGAIN.

It works well for preventing oxygen from going back in to your machine. Larger than it looks.
