HME (Heat moisture exchange filters)
#1
I would like some info from those who have used HME's as opposed to heated humidifiers. I recently finished a week using one. The first night was rough and I woke with a dry, scratchy throat. I dripped some distilled water into the filter the second night and it was better. From the 3rd night on the air felt warm and humid without adding any additional water, and I woke feeling fine.

This May we are going to Peru for 20 days. Most of those are at high elevation (8000'-11,000' above sea level). I'd like to use HME's to save schlepping my full heated unit around but I'm concerned about their viability, especially at elevation. The hostels we are staying at do not have central heating and a room heater is not guaranteed. Consequently, we may find temps in the mid to high 30's at night.

Has anyone used an HME for any length of time? Any thoughts, tips etc?

My response is probably not going to answer your questions, nut here is my experience with them.

I use HME's 4 days a week almost every week.

First, an HME will never feel as good as a real humidifier...that is just not going to happen. Also, I do not think that the manufacturers would recommend using any water and I never have to.

In more humid environments I have used an HME for about 14 consecutive days and still felt comfortable. Also, when not actually in use, remove the HME and put it in a zip lock bag.

While it may not be applicable to this trip, if you're in a hotel as opposed to a hostel or camping, run the shower on hot until you see the mirrors in the main room start to fog. I found that helps in dry climates and I can even sleep without a humidifier when I do that although not as comfortably as with an HME (d it when I forget to pack one)

There is no question as to whether HME's work, they've been used for years, it is just a matter getting used to them.

I've been wanting to try HME without buying a Transcend. Are you using a "Universal Inline HME" with your mask or do you have a Transcend?

The Transcend has a design that places the HME between the exhaust and the mask. The universal is downstream from the exhaust which doesn't look like it would be as effective as the Transcend.

Any comments/experiences will be welcomed.

Read my post again, I haven't run into anyone on the message boards who uses an HME as much as I do. I've used the same one for 14 days straight and it was still effective. I've never added water do an HME.

I never tried the Transcend one but the inline works adequately as far as I'm concerned and I cant sleep without either an HME or a Humidifier............I take that back, on the rare occasions where I forget to pack an HME I have gotten buy in my hotel room by running a hot shower until the mirrors in the bedroom fog up a bit. That usually provides enough humidity for me to fall asleep.
