Nispira CPAP HME Heat Moisture Exchanger Filter for Z1, Z2, 6 Count

This little accessory helps to humidify my Res Med Mini CPap machine. It eliminates the need for a water chamber and distilled water when I travel. Makes it so much easier when you're on the road.

Great product for those traveling with CPAP. You need to buy an adapter for your CPAP machineto bypass your humidifier but once you have it, it is much easier to travel and use this moisture exchanger then finding distilled water in a foreign country. My husband says his last about a week for him.

Used it on a 5 day camping trip. I was using a battery component. So, I could not use the humidifier on my c-pap machine, it would run down the battery fast. I use one for the entire 5 days. It works great.

These things are worthless. I still had dry mouth, but also a coating of dried phlegm in my throat. Awful !!

Not sure they really provide humidity, but appear as advertised

I got this to use on my recent trip to Japan. I didn't want to try to find distilled water, considering I can't read Japanese and was not able to tell what was distilled, purified, or mineral water. On my CPAP I purchased a water tank replacement plug (when installed the resmed machine knows there is no water tank and adjust automatically) using the plug also made the CPAP shorter and easier to pack. No water to carry from place to place, or find. I was there one month and used just one filter. I have the others in reserve for future trips and cruises. Most days I couldn't tell much difference between mouth/nose drying then when using water tank at home. As stated in advertising be sure to use with correct mask/cushion, it will not work with other type masks. I have used other similar filters which attach inline on the hose with good results also, but no longer use that style mask and had to switch to these.

I use a standard CPAP with a heated water reservoir at home. For travelling, I bought one without a water tank and hoped these would help humidify the air to prevent dry mouth/throat. I tried with and without these and they do help, but not enough to give me a comfortable night's sleep. I'm trying the OEM brand right now. They are much more expensive and so far no better. So if you need to use a CPAP without a water tank, these may be your best choice.

These are good for no more than 7 days but they work with travel size CPAP machines. Much better than trying to haul around distilled water and all the added stuff. Humidity levels are such that your not all dried out but some people may find not humid enough for them. I found they work perfectly. I but them keep them on hand for when I travel.
