M series silencer and Pur-Sleep

[ibthebest]

I recently added the M-Series silencer and like how it seems to quiet down my machine some. However, I am addicted to Pur-Sleep and this is now a problem since there is only a tiny hole that allows air to come into the machine (which is on the top of the little box). Has anyone tried just putting the liquid on the sponge filter? I know there was past discussion about having the Pur-Sleep in-line and how that may not be good for you. Secondly, does anyone think using the silencer might shorten the life of your machine? It sure seems like it severely limits the amount of air coming in the machine compared to the amount it puts out.

I still use the IN-LINE unit for Pur-Sleep & Love it ... Use about half the product it seems to last longer ......
Also found that by putting the machine on a silencer pad < sheet of Styrofoam covered in felt> it worked as good/quite as having the silencer on & after lowering the machine below my head level even removed the silencer.. the wife doesn't even hear it anymore or only when she wants to make sure its running.
Have more sound from the exhaust on the mask vents --- I have made a cheese cloth bubble to cover the vent that has cut that noise way down... .

For the past 5 years, I've been using a Respironics RemStar Pro machine. That machine had a cover over the filters with just a little slit to let the air in. It's lasted 5 years with just that little slit and it's still going strong. I just wanted a data-capable apap and after 5 years, was allowed to replace it so a couple of weeks ago, I ordered a brand new M Series apap from cpap.com and while I was at it, I ordered a bunch of other stuff like the whisper cap and Pur-Sleep. The whisper cap because I had read a few posts that complained about the noise and because I figured that if they made this, it must have been for a reason. I had never used the Pur-Sleep stuff but had read a lot of positive posts about it so I decided to try it.

I was surprised to see that the air intake for the M series didn't have a cover -- just naked filters. I was happy to have gotten the whisper cap since that covered them. I personally find the M series already quieter than my RemStar Pro so I don't need the whisper cap for the silencer aspect but rather as a cover to the filters.

However, I didn't expect the Pur-Sleep to be just a dish you put behind the xpap with a pad & aromatherapy stuff in it. I inadvertently offended Sleep_Guy in another thread by saying that and I really don't mean to. I know he's worked hard to create this. I just expected it to be attached / covered. In any case, because of it just being that outside dispersal, I also don't see that it can be used with the whisper cap. I wish when I bought it that there had been some comment to the effect that it isn't effective with the whisper cap but that's life. Someday I'll get around to trying it just open in the bedroom for hubby to share the scent too. For now, it's put away with other xpap stuff I don't use like previous masks, etc.

For you, given that you've used Pur-Sleep before and you like it, I hope you find a way to manage. Good luck.

You mean the Whisper Cap? Hole seems a bit small doesn't it. You would have to ask Pur-Sleep guy but I don't see
any problem with putting a drop on the foam if you are going to inhale it anyway, you can always wash the foam.

[frapilu]

That's the whisper cap I'm referring to and that I assumed Bert_Matthews was calling the silencer. You're right, snoredog, we shouldn't assume -- we should be sure we're talking about the same thing.

I didn't try putting a drop of the aromatherapy stuff on the foam filter but I guess it might be an idea. I guess I'll wait to hear what Sleep_Guy has to say. I might pull the Pur-Sleep out of storage and get around to testing whether hubby & I like the smell then try this if we do (don't want to put it on the foam filter then discover that we really don't like it after all.)

Sigh, sometime I'll take the time to learn to post an image here. Hawthorne PMed me instructions that were very clear but I haven't had time to try.

Thanks snoredog. You're right on, as always

Anytime products are used some other way than they were intended to be used, the results can be poor. Lots of things can act as solvents, so of the gasses put off in the process can be unhealthy. BTW the filter cap on the Remstar "Classic", acts as a muffler and a prefilter, it's foam lined. Jim

I'll have to check mine again but it strikes me as being an empty cube, not foam lined. It looks and feels empty but I'll see if I can find a way to look inside.

Your's is a "M"eries not a "Classic", that's probably another part they left out. Jim

Oops, sorry, misread your message. I thought you said that the whisper cap was foam lined. There is no filter cap at all on an M series so I'm using the whisper cap as a filter cap.

I'm at work and my intention was to just occasionally drop into cpaptalk.com as a multitask between things but I'm certainly spending a lot of time here this afternoon (but not reading as well as I should, as is seen above). Hope my boss isn't checking my net usage

The picture posted by Snoredog is correct. I don't think Sleepguy will post a response because it could place him in a position of recommending an application of his product, "in-line" which I don't think he will want to do. I guess I was looking for more responses like the first guy who said he had been using his Pur-Sleep "in-line" for over five years. He appears to be able to still write coherently. Also appreciated the response from the person who said their machine had operated with a little slit for intake for over five years. Are there others out there who would like to share their experiences?

Thanks

I wouldn't put liquid on the sponge. It would not only limit airflow to you, in my opinion, but it would not filter the air as it is designed to do. I too use Pur Sleep, and see your dilemma. Can you just sit the blue cloth pad on top of the machine versus on the ceramic dish? By this response, am I understanding your issue?

[gasp]

Whoa, a silencer? It just sank in that you said you put a silencer on the machine. My M series A-Flex is already pretty quiet. I didn't know they made silencers.

[Billmanweh]

This is where my mind went...

[SleepGuy]

Looks like I need to buy one of those silencers and give it a try....

My thoughts without having experimented with it:

1. The current PurSleep platform should work fine with the whispercap if you can figure out how to place the diffuser about .5 to 1 inch below the hole / air intake. Put your hand around it and figure out where the best negative pressure zone is and use it. You might have to stack up some books or equivalent but it should work fine.

2. I would not recommend using aromatics on the filter, especially if it's foam. Essential oils have a solvent effect, especially in contact with plastics (that's why they eat your furniture finish and paint). Who knows what might happen in a foam filter??

3. The diffusion properties of a foam filter will likely be different than the other diffusion materials used in the product (rate of absorption, surface area, rate of diffusion, etc).

And France, you did not offend me in the least on your other thread; I'm sorry if I sounded offended or defenses. That was not my intention. I was simply trying to answer your question.

I have had the M series silencer cap for about a week now and I love it, the M series was very quiet before I put the silencer on but now it is even better and i've noticed that my Swift 11 exaust isn't quite as loud as it used to be...

It's definately worth the buy, as a matter of fact it's one of the cheapest and best investments i've made regarding cpap supplies besides the pur-sleep and the aussie heated hose, I reccomend anyone to take the plunge...
