- Morning, everyone.
I have a few concerns regarding
the foam used inside this machine.
It's by a company called DeVilbiss,
this is the DV5 series.
In America, they call it the IntelliPAP,
in here in Australia, they refer to it as the SleepCube.
Now, DeVilbiss has put out a statement,
they put this out a while ago and I was like,
"Cool, no, they say everything's okay."
But the more I thought about it,
it feels to me like there could be a bit of a problem,
all right, I'll read you the statement.
"Drive DeVilbiss Healthcare has not identified any issues
similar to the ones identified by Phillips."
Sounds pretty good.
"Our DV6 series CPAP devices use a silicone foam
for sound abatement.
This foam is not related in material or design
to polyester polyurethane foams."
The ones used in Phillips, that sounds great.
"In addition, although our DV5 series CPAP devices
do use polyester polyurethane foam for sound abatement,
there is a wide variance in the mechanical
and chemical properties of these foams
based on their specific formulations.
The processes used to manufacture them
and the unique design and performance characteristics
of the devices in which they are used.
Drive DeVilbiss performs
constant continuous post-market surveillance
and analysis of sales, service, and repair data,
which has not detected any problems
similar to the ones identified by Phillips,
since the DV series was introduced in 2007.
So this machine's been on the market for a long, long time,
but you also have to remember
that many of those Phillips machines that were recalled
were also released a long, long, long time ago.
So just because they haven't noticed any problems
doesn't mean that there isn't any problems,
that's what I'm saying.
And with the Phillips foam gate saga,
the only real reason that it came to light was because
people were noticing in that DreamStation chamber,
because you can see right into it.
They were noticing the black foam debris
inside that chamber,
'cause it's very easy to see it.
Whereas with this DeVilbiss DV5 series,
the chamber itself is all sealed up.
You can't, and it's a blue color,
you can't actually see inside the chamber,
so when you go to empty the chamber,
you literally take off the clip,
pour it down the drain, and then fill it up again.
So I just don't think it would be that obvious.
So I wrote to DeVilbiss anyway and just asked them, I said,
"Look, guys, I am concerned
about this polyester polyurethane foam.
I know you've said it's different to Phillips,
but it looks the same, it feels the same,
and it reacts to ozone the same,"
'Cause I did a little experiment, which I'll show you soon.
"Do you have anything more concrete?"
And they replied and said,
"We only have the official statement
from the corporate office.
I will forward your concerns,
but since we don't have any complaints related to our foam,
I don't think there will be a different statement."
And I haven't received a different statement, so...
But anyway, look, we'll have a look inside the DV5 series,
I'll show you the foam, and I'll show you what effect
ozone had on the foam,
it's pretty similar to the Phillips stuff.
So, yeah, I don't know where this is gonna go,
but I think DeVilbiss needs to come out
with some lab analysis of their foam,
show us some real data from an independent company and say,
"Yeah, look, the polyester polyurethane foam
in our machines is different.
It doesn't break down from heat, and humidity,
and all that sort of stuff."
And give us a little bit more confidence in their product
because this statement is a little bit wishy-washy
as far as I'm concerned.
All right, so here we have it, inside the DV5 series,
and this is the turbine in here.
So the foam sits all around the outside.
There's the turbine, that's the air intake,
so it's certainly not sealed away from the air intake.
Now this is foam I've treated with ozone,
so we'll get back to that in a second,
let's put that over here.
And then under that there is more foam,
and then I'm not sure, is that the only foam?
And then there's more foam,
under here as well.
All right, so, there's a lot of this stuff in the machine,
all right?
This here is the Philips foam,
this is the DreamStation One foam,
and this here is the foam from the DeVilbiss machine.
So I just wanna, this is what I want to show you,
like it's...
Hold it up and just give you a really question look.
But you can see that it's, like if I hold that up,
so maybe a tiny bit of difference,
but it's very, very, very similar.
Let's have a look at the ozone tests that I did.
So this is the Phillips stuff,
and I won't get it out of the bag,
you've seen it all before, but you can see that it,
the ozone just nukes it and just becomes terrible.
But I did, I nuked this one for a little bit less,
just for a couple of days with the ozone,
and you can see that it's disintegrating the same.
This is the DV5 series foam that I showed you.
So it does disintegrate with the ozone.
I don't know if it's going to disintegrate with the heat,
but the fact that it reacts the same to the ozone,
it just doesn't sit well with me
that they've come out and said,
"Oh, don't worry guys," you know,
"our foam is different in the chemical nature."
It's very, very, very similar.
DeVilbiss, I think you need to come out
with some lab analysis to prove to us
that your foam is okay.
I am gonna do some videos just anyway,
on how to take the foam out of this device.
It's not within a sealed chamber, as you saw then,
I just took it out pretty easily,
so you can take the foam out of this one.
All right, guys, that's it.
