These inline HME Filters are easy to install and should not require re-calibration on most CPAP machines. Simply attach the HME between your mask and your standard CPAP or BiPAP tubing.
The Universal Inline Heat Moisture Exchange (HME) by Breas is an inline humidification solution unit for use with most CPAP machines. It is a waterless humidification that requires no additional power making it a great alternative to large humidifiers.
While it is important for the user to check the CPAP manufacturer’s recommendations, most inline filters do not require air pressure calibration—it’s as simple as plugging it in and using as normal.
