Setup with HME filter
If no humidifier is used, we recommend using an HME filter to maintain the moisture
of the respiratory gas. A “combined filter” consisting of an HME filter and a bacterial
filter is well-suited (e.g. Medisize Hygrovent HMEF).
Please note: When using a HME filter, read the user’s manual from the respective
manufacturer. In particular, follow all information related to replacement intervals.
