Filter change – filter service life

The following are the manufacturer recommendations

Check the air filters (unit, external and room filter) regularly, depending on the degree of soiling. Select shorter change intervals if a lot of dust or dirt is produced. Change the air filter as needed. Only use original air filters.

• Change exhaust air filter ISO Coarse 80 % (G4) and outside air filter ISO ePM1 55 % (F7) every 3 months.
• Change optional external filters every 6 months.
• Change optional room filter every 2 months.
