Resmed 10 HEPA filters?

[RonS]

I've seen some pollen or "hypoallergenic" filters, are there any true HEPA filters for the machine?

If not, anyone have any hacks to make them?

TIA

[Pugsy]

None that I have ever seen and no hacks that I know of.
I am a bit leery of doing that sort of hack because I don't know how much using a different filter material might impact the machine pulling in the air.

The most I will do is double filter...one regular filter and one hypoallerginic filter at the same time.

Nope.

You can put one of the ball shaped Antibacterial filters in the hose, which I do, and it seems to help with my allergies.

Absent that, all I can think of doing would be to build a box to put the cpap in, and have one wall of it be a HEPA filter.... because true HEPA filters aren't small.

Thanks!

Are there any specs for any of these resmed filters?

I might just go ahead and try to design some sort of a filter attachment; Do you think an enclosed box would be a good idea with all the heat going on? I'm not sure there's be enough ventilation for cooling purposes over and above the air draw for the therapy. I'm not in front of my machine right now but I think there's just a hole for the actual intake, maybe with some prongs in front of it

I've thought about the heat issue as a mental exercise before.... there's very little extra heat... the circuit board creates a little... the fan motor itself is surrounded by the airflow,

(all the air flows inside the plastic housing) and most excess heat from the humidifier is taken out with the airflow. Plus, there's 20+ liters per minute of air being pulled into the box. I can't see heat being an issue.

While I don't have anything as effecient as a HEPA on my Autoset as is on my O2 concentrator, I have experimented from time to time with a mask-mounted AB filter. What I do and have done since day one is use dual filters in my machine's intake inlet. Simply one OEM filter stacked atop the other. Tight fit but no issue with filter access door closing/locking. Doesn't seem to affect anything adversely but can't say it does anything more positive than make me feel a smidge better about the air I breathe.

Nice pictorial.

I have put a Respironics M Series BiPap in a hotel nightstand drawer and it was fine, but then again the drawer was necessarily open a bit. You're probably right.

Maybe the first step is put it in a box with a remote thermostat. Try it with the intake facing the opening and then 180 degrees away. I have a spare new car cabin filter I can use as a temporary measure to seal the opening and create the negative pressure environment that will stop convection out of the box as a variable. Probably have an Apria supplies shipment box handy, too!

I have a respironics M series foam filter behind the resmed wafer thin white filter. More than that causes an error from the machine. The foam filter does catch lots of fine dust that is making it past the silly white filter.

I should note that I have a *large* whole room hepa filter running all the time, there is very little dust in the room, yet some does collect in the filters over a few months. I'm not so concerned about nightly use, but more when I travel which is rare.

The foam filter is supposed to be on the outside on the respironics, then the fine filter.

The resmed white filters are clearly worthless for fines, as the respironics foam filter is catching more fines.

It is true in a respironics application that would be the correct order, but sadly this is a hack to add extra filtration, it's not ideal.

Re: true hepa filters; they are so thick due to folding to provide more surface area for air to pass through since the material is so restrictive. There's no filtration advantage in having the filter unit be thicker. I don't know if asingle piece of hepa filter material would be too restrictive for the machine. I suspect it would be. Maybe I'll try a piece when I have a hepa filter that needs to be tossed, in 10 or 20 years from now.

Your best bet, IMHO, is to buy a Honeywell Hepa air cleaner for your bedroom. Keep the door closed. Keep your windows closed. Makes a huge difference (I do this for my disabled brother). You can buy both unit and replacement filters from Amazon. Then just use the knock-offs in your machine as provided by your DME. Keep in mind that no portable filter is going to even come close to a hospital grade one - those are some powerful motors! But the Honeywell works well and the price is about $130. They do have some with a smaller footprint around $200.

For me, I found my allergy issues lessened considerably during the summer by just using Resmed BRAND filters. The knock-off hypoallergenic filters are OK, but in a blind test (family members changing out filters), Resmed brand filters worked better for me. They may make no difference for you. So, I use them from about April to October and then knock-offs after that.

Buying your own Hepa Air filters and cutting to size has two problems. One is that you can restrict flow which may/may not reduce the life of your unit. Second is that unless you have a means of sealing the ends, you could be breathing in micro filter pieces, which is bad for you.
