Most furnaces aren't using liquid fuel, and aren't prone to backfiring into the intake, and if they do that small amount of medal won't help.

of course, the whole point of my post was that the reinforcing material goes towards the blower, to keep the filter material from being sucked in...

For most of the filters I've seen, it probably doesn't matter that much.

It appears the "right side" is "the side that is less likely to shed fibers into the machine." Some of the filters have an obvious plastic mesh on the side that face the machine. I've seen some filters that seem to have some sort of plastic spray on one side that locks the fibers on that side. That side would seem to be the one to go toward the machine, but it's DARN hard to see. They really need to mark the correct side with "this side toward machine."

I think some of the newer genuine filters and many of the counterfeit filters don't have an obvious "less fuzzy" side. I think the ambidextrous genuine filters are designed not to shed out of either side. The counterfeit filters may be a different story.

I use only the ResMed brand hypoallergenic filters in both of my ResMed S9 AutoSets and "I" can't "readily" detect any difference from one side to the other.

When I take it out of the sealed bag & look at it, I think I see a side that should face into the S9. But, by the time I get to the S9 & having looked at it several times on the way, the other side looks like it should face into the S9.

So, I just assume it does not matter, and put it in whichever way it is facing by the time I get to the S9. Scientific it ain't, but it causes less stress that way.

because of the superior design of the resmed filter holder, their filters don't need a reinforcing mesh, they've got all those little posts to help hold it up. so they don't have a front and back side

they're also pretty much curious kitten proof, unlike the respironics.

You guys really need to watch the condescension and arrogance. It is unbecoming and boorish.

but you can't please all of the people all of the time.

now, as to you, and your cowardly, gutless, sniveling ways, I'm quite happy to please you NONE of the time.

I know that if we were to meet face-to-face you would not make those cowardly comments. But the distance makes you feel like you can do and say things you can get away with when no one can reach your scrawny feeble puny little puss.

I love it when you look in the mirror and talk to yourself.

In the Grand Scheme of life if I am registered or not doesn't mean diddly.
It is just what losers bring up when they have nothing else of value in a debate.

And fwiw, I am registered.

again, staring in the mirror... nice.

and, doesn't really matter if you have an account, if you're too chickenshit to post from it...

regardless... if it makes you feel like you're worth something by hiding in the shadows and making little sniping comments in threads that are otherwise dying out, you just do whatever it takes to continue believing you have some self worth.

The original question was about PRS1 filters. I think the S9 filters don't matter which side faces the machine.
