AIRTUNE AIR air filter

The AIRTUNE AIR air filter is an additional component for connection to the air vents of Truma heaters in motorhomes. The installation is very simple. Simply attach the filter to the back of the end piece/outlet and unpleasant particles are filtered out of the heater before the air is discharged.

Area of application: Filters dust, pollen and other particles at the outlet of the Truma heater and thus ensures that these do not enter the air in the room.
