Stop the leak before the leak stops you! Leak prevention Leaks for Respironics System One Humidifiers
These inlet and dry box seals are for the PR System One Humidifier (widely known as the 50 series) and System One 60 series humidifier by Philips Respironics.
The inlet seal connects your CPAP machine and the humidifier. The dry box seal connects the water chamber and the inlet prevents pesky water from slipping through potentially causing unnecessary unwarranted headaches with a potentially defective CPAP machine.
