This pack contains 2 x filters for use with the Greenwood HR155 and Zehnder CA155 heat recovery units.
To ensure that your ventilation system continues to operate effectively it is important that it is properly maintained. An important part of this maintenance is cleaning and replacing the filters to ensure airflow and air quality do not reduce.
