Quattro Mask Modifications
I know it’s a no, no but I also like sleeping with my wife with out a pillow between us. I like the Quattro mask and it is much quieter then the Ultra Mirage BUT they need to deal with force of air coming from vent.
My remedy is show in the attached picture. I also do not want to restrict the air from the vent. So I measured the air with a anemometer. With my deflector on the mask or off there was no change in the flow volume. The flow rate chart for the Quattro mask says I should have about 25 L/min at 5cm h20. I found that I got a flow of 33 L/min @ 5cm h20 with or without my deflector. I used a piece of plastic because it was handy but a popsicle stick taped to the mask would be equal to my plastic.
I can not advise any one to do this but it works for me.
Hope this may help some one sleep.

That's pretty cool. I wish I could get mine to stop leaking like a racehorse on steroids.
