Hi,
I thought I would share an observation from my 420E downloads.
A long time breeze user, I also find the swift is comfortable, and have been occassionally sleeping with it.
In comparing the leak rates from my 96 hour detailed report I have the following leak rates.
Breeze - all hourly averages are either 0.3 or 0.4
Swift - hourly averages are 0.6 0.8 and 1.0
While I do not wake with leaks, and find the swift comfortable, I must have a superior seal with the breeze.
Anyone else care to share their leak results with masks or nasal pillows you may swap between.
