The OPTIONAL PR One smart heated humidifier(Optional) analyzes ambient conditions to deliver optimum humidity while reducing rainout.

The Philips Respironics PR One CPAP humidifier and water chamber design are breakthroughs for managing rain-out and water damage. System One Humidity Control technology analyzes ambient temperature and patient airflow to reach relative humidity at the mask. Choose from 5 levels of relative humidity.

System One is the first humidifier in the industry which accounts for room humidity. Sensors inside and outside the CPAP machine closely monitor changes in humidity and prevents condensation from forming inside the tube.

Dry Box technology is another breakthrough in reducing water damage to the CPAP. Several unique designs are incorporated into the humidifier to prevent water from exiting the chamber. To start, the air outlet port has been moved from the side of the humidifier onto the top. This centers the entire delivery; minimizing the total water displacement around the hole. The water chamber is outfitted with one-way valve, between the machine and the humidifier. Any water that manages to escape the chamber gets trapped within the Dry Box, which acts as a reservoir for any water ingress past the valve.

System One and Dry Box Technology make it possible for the PR CPAP machines to be truly spill-free. This humidifier, even with a chamber filled to the "Full" indicator line, can be tilted, shaken, and even turned upside down without water leaking back into the device.

Philips Respironics wanted a machine to achieve optimal pressure no matter which mask is used. Resistance Control is the solution, a numbering system on all of Respironics CPAP masks based on variable resistance characteristics. Each number instructs the device to compensate for different mask types. 
On-board memory has been added to the CPAP as well as storing information on a generic SD Memory card and reads through any SD card reader. This machine only tracks and shows compliance data through the on machine display or through the Encore Software.
