These inline HME Humidifier Filters are easy to install and should not require re-calibration on most CPAP/biPAP machines. Simply attach the HME between your mask and your standard CPAP/BiPAP breathing tube. After that, turn on your machine and experience a steady flow of humidified sleep therapy air.

When using your CPAP/BiPAP the HME Filter captures heat and moisture from the air as you exhale. It then returns heat and moisture to the breathing circuit with each inhalation creating a comfortable, effective and convenient humidified breathing system.

Usage Information: Heat Moisture Exchange Humidifiers 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.)
