Just now (June 19, 2005) looked at the sleepzone site - $89 U.S. dollars and free shipping.

At Radio Shack I got the 12 volt 1 amp DC converter (Radio Shack part# 273-1776) and the "M" adapter to plug the heated hose in to an American electrical wall outlet. Less than $20 for the converter.

wrap some teflon plumber's tape around the "plug end" of the chamber if you have problems with it leaking there. That took care of that odd leak for me, and I got the hint from someone else that it also worked for.

That would require me buying plumber's tape...fabric is much easier to come by in my house for some reason then hardware stuff (though I do have lots of window screen since I can use it to machine embroidery on).

Yesterday, got my 420G (the 420S didn't come yet) from the DME and I got the Swift because it was lite and option to read with glasses but the Swift was noisy like was discussed in this thread. The air swishing noise kept waking me up. I will try the trick with the piece of wired mesh today to see if it lessens the noise or a larger nasal pillow. I tried the Comfortlite with nasal pillows at the DME yesterday and it was much quieter than the Swift but it didn't give me the option to read with my glasses so I passed.

Hmmm...

I rotate the barrel maybe 5 or 6 times for each 20 to 30-minute nap, and it still makes a loud whooshing sound. Maybe it just doesn't fit right. The sound is from the air that I am supposedly inhaling being forced out through the exhaust vents. Maybe it's because my breathing is quite shallow at times.

The swift takes a little getting use to. The real problem with it being noisy is when the exhaust vent is blowing straight onto something like the bed clothes. If you can adjust the bed clothes so that the exhaust blows into clean air it is really quiet.

The other problem is blowing onto your arm as you sleep and waking you up. I just make sure that I keep the bed clothes between my arm and the swift, and the swift a good few inches from the bed clothes.

Why not try listening to the mask as you move it closer and further away from pillows and bed clothes? You may find that the noise is much more controllable then you thought.

You don't use a wire mesh, you use a nylon mesh. And it doesn't have to be from a orange bag, it can be from a bag of pistachios, a bag of cherry tomatos, anything you can find. Takes only about one square inch of the netting. Make sure it is all inside the barrel or you will have more noise and leaks. Nearly all nasal pillow interfaces make noise when you inhale, and the higher the pressure the more the noise.

I had more trouble with noise with my Swift the first few weeks I used it. I had pretty much forgotten about the noise it made until this thread popped up again. I can't really explain why, but the longer I've used it, the better I've been able to fine tune all the pieces, strap tensions, etc so that now it seems the air noise is very minimal. I also no longer notice it blowing on me.

I went through a period a few weeks back where I noticed if I didn't have things set just right the noise level would shoot way up. I can't tell you specifically what I do now, but these problems have gone away for me. It's the rotation on the barrel, the tension on the straps (one pulls up, one pulls back), how it sits on my lip, the alignment of the pillows with my nostrils, the placement of each strap on my head, keeping all the pieces clean and assembling them correctly. The exact setting of each little thing affects it and getting it just right involves subtle adjustments that I do sub-consciously now. One night I noticed air noise from the end cap, so I got up, took it apart, lightly cleaned and reassembled the whole thing. Problem solved, everything seated and sealed perfectly. This particular experience convinced me it is a good thing to take it apart completely, clean it, and reseat all the parts regularly.

I use a little hunk of mosquito netting and it makes a world of difference for me. It seems like it is quite a bit quieter when I use my Remstar (Pro) and louder if I use my PB 420e. I still have to wear earplugs every night. I thought I threw my money away on the Swift, but now I use it nearly every night. I just adore starting the morning with a Nike swoosh on my face!

Inserting mesh into the cylinder didn't quieten the sound appreciably for me...tried several types of mesh and various amounts.

I think I could have eventually gotten used to the constant whoosh noise, but the feeling of the exhaust blowing on my arm was too much. Probably wouldn't bother most people, but was a major annoyance to me; especially when I had other interfaces I like that don't require such painstaking procedures to get a clear path for the exhaust.

swift is nosiy if the fitting is poor

I find that you need to strap the hose in such a way that it is pulling the nasal pillow upward and the noise would disappear

it is definitely much better than the activa now sitting obsolete in the box,

The only "whoosh" of air I've heard is on inhale, and if you use the net that is so minute as to be totally silent. Wearing earplugs just increases any sound with a nasal pillow, as far as I've noticed.

Well, after second night, I think that I am getting adjusted to the noise. I did put some tulle that my wife had and it made some difference but I still heard the swishing sound so it must be just my breathing. The tulle had small holes so I might try to go to the fabric store and get some large hole one today and try it out. It might be that I just have to get use to the noise and bear it, as long as it doesn't bother my wife and I can sleep.

Well, when I started the thread it was very difficult to get over the sound, now its no problem.
