Allergen white filter

Because the logo is supposed to face out. The logo is on the non-fuzzy side.

I am wondering about this particular filter, too, PR - I read other posts elsewhere here about it reducing airflow so you have to increase your machine pressure a bit to compensate.

Do you think its effectiveness could be dependent on the machine type and blower (ResMed vs. PR, for example?) Just wondering, since when I tried both a PR & ResMed bricks last week at the DME, the ResMed seemed more 'forceful' at the same pressure.

How long does this type of filter last, and is there a way to clean it periodically like the PR foam filters?

It couldn't filter the air without restricting the flow, period. When using a resmed you may notice it filters better because resmeds only use the one reusable filter which obviously does not filter very well. It is equal to the respironics foam filter - wash and reuse.

Using the white filter along with the foam filter in a respironics is normally more than adequate.

obtw meathead- I have tried it which is how I know it clogs right up when it gets moist.

ps. it is a disposable filter and cannot be cleaned any way any how.

there's no way to clean them... they're disposable

cpap.com, and other places that sell them, say to replace them when they start getting dirty looking, just like the extra white filter that goes behind the foam filter.

they *do* reduce pressure a little, which is why most of the resmed machines have an AB filter setting, to tell it whether you're using one or not.

the PR auto manual says this:

Note: If required, connect a bacteria filter to the device air outlet, and then connect the flexible tubing to the outlet of the bacteria filter.
Note: When using the bacteria filter, the device performance may be affected. However, the device will remain
functional and deliver therapy

is it better to not use them? probably. is it better to use them and be able to sleep with the cpap, or not use them and have your nose clogged up completely by allergies and not be able to use the cpap?

that's up to you

and, of course, if you don't think they help, don't use 'em!

as to that, as long as both machines were functioning properly, they would both provide the same amount of pressure.

however, if they weren't set up properly, (mask type, hose size, hose length, etc) then they could have been delivering a different pressure, even though the 'cm' setting was the same. and, also, if cflex or epr was on, or off, that would change how it feels to breath against the pressure.

without knowing exactly how each machine was set, it would be a total guessing game as to why you felt what you did

Huh?
How does having the slick plastic like side facing out going to grab the particles of whatever?
Who told you that the logo goes out?
It's always been the fuzzy side out. Logo faces the inside of the blower unit that you can't see.

Actually it could have been that the PR S1 had one of the Flex exhale relief settings on...and maybe the ResMed didn't have EPR exhale relief on. That little bit of Flex can gentle down that pressure a little.

Edit:....It appears that with the new name brand Respironics filter with the logo on them that the soft fuzzy side is now the side with the log printed on it. So with the logo filters...that would go to the outside. Aftermarket filters won't have a logo so a person has to carefully feel to determine which is the soft fuzzy side.

Don't the resmeds automatically increase the pressure when you put on the slim hoses.

You know I don't know exactly what those machines do with the slim hose vs the 22 mm hose. It's going to show the same on the LCD screen.
I don't recall what adjustment is made or how they figure it. I do know it makes a difference though...but as to how much and what it might feel like I have never tested it.

Maybe tomorrow if I have time I will dig out my old regular hose and play around with my S9 to see if X amount of pressure feels any differently to me with either hose. I am using the ClimateLine right now.

I do know that the S9 at a pressure of 10 without EPR on feels much stouter than the PR S1 machine at a pressure of 10 with AFlex set to 2. The PR S1 is easier to exhale and get into a breathing rhythm with. I tested that myself back when I got my S9 VPAP and wanted to see what EPR felt like.

yup, the fuzzy goes out, the reinforcement bit goes towards the blower, to keep the fuzzy from getting sucked in. standard filter operation

they automatically do it if it's one of the climateline hoses, they can tell whether it's the slim or regular size climateline, if it's not a climateline then you have to set the hose size in the menu.

OK, so where does it say "logo facing out"? Nowhere, which is my point. If you check google images using the word "mesh" what do you see? You see a lot of patterned materials that look very very similar to the texture that is present on the logo side of that filter. That side could definitely be describe as "fuzzy" also. It's pretty soft when you're looking at it and it's actually softer or "fuzzier" than the non-logo side. It's totally unclear which way it goes. And it's painfully easy to correct that confusion by saying "the logo goes in this direction" or "that direction".

The narrow hose reduces the volume requiring the machine to work hard to maintain the same amount of flow. Resmeds solution was to boost the motor up to compensate. Don't ask me why they went to those narrow hoses to begin with.

the respironics filters I've seen, one side has a plastic gridlike surface, that goes towards the inside, the other side was more of a fuzzy filtery kind of thing. that goes out. so that the plastic grid can keep the fuzzy stuff from being sucked in.

are your filters different?

they're lighter. that's the only 'benefit' I've heard... presumably for folks that let them drape off the side of the bed, instead of hanging over the headboard or something.

Guest wrote:Don't ask me why they went to those narrow hoses to begin with.

Lighter weight or more flexible maybe? Heck even Respironics made a 15 mm white Performance hose and their 22 mm was pretty darn nice. I always wondered why bother but they did it.

Amenite wrote:OK, so where does it say "logo facing out"? Nowhere, which is my point.

Because no one who actually uses this stuff has any say so in practical design features or instructions.

Most DMEs don't supply OEM filters anyway. They stock the cheaper aftermarket filters so they make more money
Heck for years my Respironics filter that were OEM didn't have a logo to even help out with which way it went.
For sure none of the after market filters had any logo to help out. It was only very recently that I saw a Respironics filter with a logo.
So yeah, piss poor instructions...what else is new? DMEs are supposed to show people how to do this stuff and sometimes they might even do it but sleep deprived people can't remember much.
