About This

• REPLACEMENT: Heat Moisture Exchangers should be changed as needed when humidification levels appear to drop -- usually about once a week with proper storage and nightly use. When not in use HMEs should be stored a sealed plastic bag (i.e. a ZipLock). The HME will immediately begin to collect moisture and humidity when exposed to air. (Note: In-Line HME packaging originally recommended replacement of the HME on a daily basis; however weekly changes have been found to be more effective and the packaging is being updated to reflect this.)
