Philips Respironics Dry Box Seal & Inlet Seal for PR System One REMstar Humidifiers
This package includes two seals. The Dry Box Seal connects directly to the PR System One humidifier chamber. The Inlet Seal attaches between the humidifier and the CPAP or BiPAP machine. Both seals must be in place at all times when using a humidifier with the PR SystemOne Sleep Therapy device.
USAGE: For optimal performance these seals should be replaced every 3-6 months or whenever they appear damaged, cracked, or worn. If not replaced regularly users may begin to experience leaks between the heated humidifier and the CPAP machine as the seals deteriorate.
