The exact replacement filter set for the Zehnder ComfoAir 160 unit, part of the wider ComfoAir range. Both filters in the set measure 237x150x24mm.
- G4+F7 (original) — genuine Zehnder specification with G4 extract + F7 pollen supply filter
- G4+G4 (original) — basic general-dust pairing for lower-allergy households
Note: the ComfoAir 160 and ComfoAir 200 use different filter dimensions despite similar model numbers — always confirm your unit measures 237x150x24mm before ordering.

We’ve gathered answers to the most common questions about our products and services. If you can’t find an answer here, please contact us directly.
Is there an activated carbon filter for Zehnder ComfoAir Q units?
Yes. We stock an original Zehnder activated carbon set for the ComfoAir Q350, Q450, Q600 and E350 (G4+G4 AC). The carbon layer absorbs odours drawn in with the outdoor air — traffic fumes, wood smoke or a neighbour's barbecue — while the G4 media still filters coarse dust. It replaces your standard set, so use it when odours are the main problem and switch back to G4+F7 when fine dust and pollen matter more.
Do Zehnder ComfoAir Q350, Q450 and Q600 units use the same filter size?
Yes. The ComfoAir Q350, Q450 and Q600 — and the ComfoAir E350 — all take the same filter set, available as G4+F7, G4+G4 or an activated carbon version. Older ComfoAir models (70, 160, 180, 200, standard 300/375 and 350/500/550) each take a different size, so check your model on the front panel before ordering.
Why do Zehnder ComfoAir filters need more frequent checks in high-pollen seasons?
Because ComfoAir's F7-class supply filter is specifically designed to capture fine airborne particles including pollen, it can load up faster during spring and early summer than during the rest of the year. Checking filters monthly during peak pollen season, even within the standard 3–6 month replacement window, helps maintain steady airflow and allergy protection.
What filter class does Zehnder use in ComfoAir units?
Zehnder ComfoAir units use two filter classes:
- G4 (ISO Coarse) — protects the heat exchanger; used on the extract side
- F7 (ePM1) — for the supply air, capturing fine dust and pollen
For most ComfoAir models we stock both a G4+F7 set and a G4+G4 set. The G4+F7 set is the better choice for allergy sufferers and homes near busy roads.
How do I find the correct replacement filter for my Zehnder ComfoAir unit?
Find the exact model on the unit's front panel — for example ComfoAir Q350, Q450 or Q600, ComfoAir 350/500/550, ComfoD 350/450/550 or Zehnder EVO. That is the fastest way to match the correct filter set in our catalogue. If the label is missing, measuring the extract and supply filters directly identifies the right size just as reliably.
What size is the Zehnder ComfoAir 160 filter?
237x150x24mm per filter — don't confuse this with the ComfoAir 200, which uses a different size.
