Nispira in-Line HME Heat Moisture Exchanger Filter Compatible with CPAP/biPAP Machine & Mask, Z1, Z2, Dreamstation, 6 Packs

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.

I didn’t want to bring the humidifier attachment while traveling. These worked great for me. Not as good as when the humidifier is attached but close. The per piece price is reasonable and allowed me to change them often too

Works well, fit is good to ResMed mini adapter, helps dry mouth, but only lasts one week

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.

I have used these heat/moisture exchangers with my travel CPAP for several years. The past few batches have been ordered from Amazon with no problems. This batch, however, was substandard. So far, they are a total failure. I’ve tried them and they literally have broken apart in the middle of the night, thus waking me and interrupting CPAP therapy. Definitely concerned about ever ordering again from here.
