Allergy Filters for CPAP--New Guy

[Snorzz]

I have seasonal allergies to most everything &  none of the medications do much for it.  Have noticed those inline filters that go in the hose to filter out bacteria; should also filter pollen.  Also noted that the CPAP's themselves have filters for incoming air.  Any idea which would be better for pollen?  Would the inline filter put backpressure on my CPAP and make it fail prematurely?

There are filters from the manufacture that are designed to help with allergies.  Search for Disposable Hypoallergenic Filters. In addition you can use the anti-bacterial filter you mentioned. Any additional filters in line will have an impact but unless you machine is maxed out it should be able to handle it.

As I recall, the problem with the inline anti-bacterial filters is that they clog up if they get damp - which they will if you have a humidifier on your machine. They also add some air resistance which must be compensated for by the machine.
I think the hypo-allergenic intake filters would be the best thing to use.

Go look on Supplier #1 web site. At the bottom there"s a link to FAQ. Go there and check under supplies. It gives a detail outline on in-line and machine filter types.

There are "ultrafine" filters, sometimes called hypoallergenic available for most machines that are much more effective for removing pollen and dust as compared to standard filters supplied with the machines. They replace the standard filter, or in some case. are used in conjunction with the standard filter. They are placed at the air inlet to the machine. In line bacterial filters would remove all dust and pollen but there are problems associated with their use. They do increase back pressure significantly. and, according to Resmed, may effect the accuracy of sensor readings.  Also, they are completely blocked  by liquid water (not water vapor), so if you use a humidifier and have rainout problems air flow my be completely stopped.

I have a commercial ion HEPA air filter machine in my bedroom, and the door stays shut so the cat can't go in. If you have allergies year around like I do, it's best to eliminate the majority of dust and such that floats around in the air. If you do that, you don't need anything on your cpap machine other than the standard filter.

I got lucky and bought it only 1 year old at Salvation Army for $35 some years ago, because I never could have afforded it brand new (over $1,000). I just had to replace the HEPA filters, ($75) and it was good to go.

You don't really need one as good as that, but one good enough shouldn't run more that a couple hundred $$. You spend a lot of time in your bedroom, so it's worth it.
