Frequently asked questions
Is this G4/F7 set an original Zehnder part?
No. It is a compatible set, made to the dimensions of the ComfoAir E300 filter (160 × 500 × 23 mm) and to the stated filter class, by a European manufacturer of ventilation filters.
When will this set be dispatched?
Within two working days of payment, by parcel, anywhere in Belgium. If the set is out of stock, leave your email: we will let you know as soon as it is back.
How do I fit the filters in the ComfoAir E300?
The fine filter (F7) goes on the supply side, the coarse filter (G4) on the extract side. An arrow or label on the frame shows the air direction. Reset the filter indicator after fitting.
Would you rather we did it?
In Brussels, Brabant and Hainaut we replace the filters during the unit's service visit and hand you a written report.
