Universal HME Filter Replacement for Z1,Z2 HME Humidification Filter

Didn't want to pay the resmed proprietarty price for a commodity item so I hooked this up with a few short hoses and took it on vacation hooked to my air mini. Air conditioned room for 4 weeks and no dry throat. Just make sure to replace it

I love my Z2, but my throat gets too dry overnight without this Heat Moisture Exchanger. Sometimes it is not enough if the air is super dry. But I found that if I breath into it several times before turning on the CPAP machine it will last through the night. This seems to "preload" the HME with extra moisture to give it a bit of a head start. I won't use my machine without one.

I used these with my Resmed mini with nose pillows and they worked perfectly. No nose or mouth dryness. I like that they are now individually wrapped and can avoid any contamination and are fresh until opened. I use an aftermarket tube which they also fit I do feel they are overpriced however.

These cartridges are functional, helping to prevent nasal dryness. The price point is reasonable. I used this product with my travel Cpap and was very pleased.

Update to the previous low rating. The company responded to my review and have since updated to individual packaging. That is a game changer since the units worked as expected. I’m editing from one star to 4. I am impressed with how they responded to my complaint. Previous text These worked but were not individually packaged. It is important that they be sealed individually to keep them sterile as they absorb moisture and allow bacteria to grow. They weren’t even in a resealable bag. I had to transfer to a freezer bag and freeze immediately, taking one out as needed for use. I will not purchase again unless the item indicates that they are packaged individually.

Work great, helps with moisture in my cpap line. Add a little water in the sponge and helps with dry mouth

This product was smaller than expected. It also caused a lot of noise through the cpap mask. Not a good fit. Would not recommend

Great product - works with travel CPAP.
