The Pressure Valve prevents water and oxygen from flowing into your CPAP machine from your tube or humidifier. When you're using the machine, air will pass through the valve, and when it's off, the valve prevents water or air from backflowing into your mask. The valve is compatible with any stand alone humidifier or any CPAP and BiPAP machine without a humidifier.
The Pressure Valve effectively prevents leaks, particularly water. It's no fun getting water in your nose at night!
No, the Pressure Valve is only compatible with attached humidifiers.
Yes, this will work for all CPAP and BiPAP machines.
