How do the exhale ports compare on....

How do the exhale ports of the Breeze, CL2, Swift, Aura Headrest, compare, as far as direction, volume of air, and noise? I ask because the noise of the Breeze's exhale port is a small problem for my wife (she's pretty sensitive to sound...). I'd like to find a way to minimize the noise, so I wonder how the others compare.

From reading manufacturer info it seems that the Headrest would be best... Still looking for info from the posters here, though.

I have the first 3, can't say the noise from the Breeze or the CL2 bother me, but the Swift's blast of air up my nose and the cheek biting side pieces (not really alleviated by padding) are hard to tolerate, as is the tube for side sleeping, but the vents, plural, are lower down.
here is a link for a fix for the breeze blast http://www.cpapman.com/hints2.htm, sorry it doesn't hot link.
I tried it , it works - the alternate is a foam slab standing between your pillows, partitioned off, what next! scroll past the hints for the Adams mask to the Breeze filter hint,

Hrmmm, blocking the exhale port seems like it would INCREASE noise.

Anyone else have a comparison of these devices?

DON'T GO BLOCKING THE EXHALE PORTS UNDER ANY CIRCUMSTANCES!!!

You need those to vent out the CO2 that you're exhaling, so that you don't begin rebreathing CO2.

Each and every mask is designed to have a certain amount of "bias" or exhaust to prevent rebreathing.

It's not "blocking" it, it is posted on a cpap site BY the site, however , I am not advocating that anyone use it, just saying it's posted there to look at and it's up to everyone to evaluate it and make their own decision.

No not blocking, I just meant putting something in the way of the flow seems like it would make it louder.

So... Swift, Breeze, CL2, Headrest, how do the exhale ports compare in terms of noise, volume of air, direction, etc?

I use the Headrest and used to use the Swift. Between these two, I find the Headrest the better both in terms of noise and exhalation direction. The Headrest is (for me) more comfortable than the Swift. but the Headrest does require more fiddling to fit and some say it is more prone to rainout.

How so? The literature all claims it's super easy to fit.

I can't explain it, but every night I fiddle with it to make it fit correctly and then the next night I have to re-adjust it again. It only takes a minute or two. However, once you get it right, it is the most comfortable mask on the market (IMHO). Sometime I wake up and think the mask is off, when in fact the mask is still on.

in my opinion the Breeze has a stronger blast of air from the vent than the CL2 but as far as noise goes they are much the same. Can't remember what the Swift was like, but don't recall noise as a problem. we usually all disagree on noise levels of course.
