Which side of the filter to use

Postby slojuggler on Thu Apr 21, 2011 10:19 pm

Hello,

For the Philips REMstar Plus C-Flex, page 5 of the User Manual suggests under the section Installing the Air Filters

1. If you are using the white disposable ultra-fine filter, insert it into the filter area first, mesh-side facing in.


What do they mean by the mesh side. Is it the soft side or the not-so-soft side?

One side seems to be easier to breathe through (the soft side) than the other side. *shrug*

:roll:

The " mesh side" is the plastic patterned side. The "felt" side, thus faces out, there's usually a tab that you bend at a 90 degree angle facing out, that's what you pull on to remove it and replace it.
The felt side collects the micro dust from the air as it's sucked thru the plastic cap you fit over the filters. The felt side thus is what you see when checking it for replacement, it becomes gray, not white, if it's black, you waited too long to replace.' I use cpapplus.com for supplies, their filters are cheap, and lightweight tubing, they even have a tube-cleaning brush . And bacterial filters, check those out.

Slo- I'm using the same gear. I've used the Mirage Swift I, II, and LT, and now the FX. Chinstraps are hard to get right- this is the best I've found so far- fyi-

I agree with CPAPorElse. I think of it as the plastic mesh side keeps the "fuzz" from being sucked into the cpap machine.

I understand that Respironics has stopped putting the tab on the white filters because they caused fitting problems. You may need some sort of pointed object to fish the white filter out of the machine.

Thanks for the tips all.

archangle is correct. Out of the box filters shipping with the current Respironics machines are tabless. Looks like I was putting the filter in the correct way (the apparently slightly harder to breathe way).

Maybe if this keeps up, I'll just alternate between having and not having the filter on days when my allergies aren't bad.

I held the filter up against a white piece of paper under fluorescents and found the grey....had no idea that much pollen/muck was around. Good thing I mail ordered for some filters online...they are "in the mail."

CPaporelse, how is that bacterial filter and brush? I saw those before...do they appear to help any?

Thanks for the chinstrap tip. I may check that out. The Respironics one is a puzzle...good for when I'm awake, not so good when I'm sleepy :)

Have you tried this one with the Swift?

CPAPorElse Plastic cap? Did you mean grey reusable foam filter? Or did you mean I have to buy one of these things now?

Not recommended.

There is no good reason not to a) use both filters b) all the time.
No good reason not to.

Depending on your indoor environment (and if you have allergies):
Change the disposable (white) filter once or twice a month.
Rinse out the foam (gray) filter weekly.
Wash it with a gentle soap once a month.
Must be completely dry before using again.

And, yes, for the disposable (white) filter the "fuzzy" (soft) side is to the outside and the "plastic" (firm) side is to the inside of your machine.

Think of it like your furnace filter. The side that's to the inside (closer to the furnace) has some sort of a screen/mesh/whatever on that side to prevent the soft side (that collects the dust) from being sucked into the furnace.

I'm going to try one of these "pollen" filters, the white one, for the first time tonight, along with the grey foam one. I ordered them from my DME and they came without instructions. I was trying to figure out which side should face in or out, so this was helpful, thanks. I have a lot of dust in my home, and am always trying to keep it away from my machine, but figure this might be a good idea, as I have chronic sinus problems.

Someone said this filter makes it harder to breath. I haven't tried it yet, but that idea doesn't make sense to me. Wouldn't it just make the machine work harder to maintain your pressure level? :?

For the filter that goes on the back of the machine, it should not affect air flow at the mask. The machine should compensate by pumping harder. I suppose that if the filter was really clogged up, it might reduce airflow, but I'm sure the machine is designed to handle it. You might see a pressure/airflow drop if you have a big leak, I guess.

I use that filter with my machine & it is really difficult to force air through it.
Try blowing through one in the direction that the air will flow. It is tough.

I have always been concerned that the air flow will take the path of least resistance & go around the filter & defeat the purpose of having that filter at all.

First answer:
Not if you put it in correctly.

Second answer (a question actually):
Do you seriously think that a manufacturer would _design_ the filter so that it would damage either the patient or the machine?

Nonsense. There are too many underemployed lawyers who would love to make a class action suit out of that.

If that were the case, it would never go "gray" (dirty). Since they DO turn gray, they obviously work as designed...keeping the "gray" out of your lungs. It ain't rocket surgery...

I'm also trying to figure out what side of the filter to use, still not sure from the descriptions above. Both sides look nearly the same to me. Neither side looks like mesh. When the tech was explaining everything to me, she referred to a shiny side, the shiny side should go one way or the other, but can't remember which. But the user guide refers to a mesh side, I can't tell which side is the mesh side. Is the mesh side the same as the shiny side?

REMstar Auto a-flex

haven't figured out yet how to get my equipment list to show up at the bottom like everyone else. Where are the instructions for this?

Thanks

Yes, the shiny side is the mesh side.

Question - is there an online source in Canada for these filters? Please?
