Do unopened Humidx packs expire? I’m trying to decide whether or not to stock up. Thanks

I have yet to find an obvious expiration date on the box or packaging. I typically purchase six packs when I get down to 2 or three remaining depending on predicted use (secondary machine for travel).

What exactly is this?

This is a humidifying chamber that is used with a specific set up for a travel Cpap. It fits in a compartment that is on the top of the tubing that attaches to the face mask/or nasal mask. It is useful when using a travel Cpap that does not have a water chamber.

How long do they last. I’m going on vacation for 10 days. Will one last the entire time ?

Yes. One should last 30 days after opening.

I love these. They work better actually than the humidifier on my regular cpap. I use them 1 per trip for business trips and vacations. Throughly pleased. Quite comfortable vaporization. Actually retain your own humidity and moisturize the breathed air. Quite pleased.
