31-35 of 35Discover our range of replacement filters for your Zehnder ventilation unit, all made in the EU! Our selection includes high-performance filter sets combining G4 (ISO Coarse 60%) and F7 (ISO ePM1 50%) filters, designed to protect your system and improve indoor air quality.

Model compatibility
This category includes filter sets compatible with all major Zehnder MVHR ventilation units, including:
To ensure the right fit, it’s important to know the exact model of your ventilation unit, as different models require different filters. You’ll find helpful tips on identifying your device in the FAQ section.
Filter types and what they protect against
Our replacement filter sets for Zehnder units are designed to ensure optimal air quality and system performance by combining two filters with different filtration roles. Each set includes:
- G4 filters (ISO Coarse 60%) on the extract side: ideal for capturing larger particles like soil particles, large pollen grains, plant debris, insect wings, sawdust, sand and textile lint.
- F7 filters (ISO ePM1 50%) on the supply side: high-efficiency filters that capture very fine particles, including bacteria, smog, tobacco smoke particles, combustion dust, spores, and wildfire smoke particles.
Usage and maintenance
To keep your MVHR system running efficiently and your indoor air clean, we recommend replacing the filters every 3–6 months. However, this depends on your environment, if you have pets, or nearby construction.
To make the process easy, we provide step-by-step replacement instructions for each filter model. You can find them under the “How to change” tab on every product page.
Manufacturing quality you can trust
The original Zehnder filters are manufactured in Zehnder’s own production facilities in the Netherlands, France, and Switzerland. Our carefully developed house brand filters are also made in the European Union by certified manufacturers. Both are produced with high-quality materials, under strict ISO 16890 standards to ensure high filtration performance and reliability.

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.
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.
