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.
Do you offer H13 HEPA-grade filters for Zehnder ComfoAir units for severe allergy sufferers?
Yes, several ComfoAir models can accept an H13 HEPA-grade supply filter in place of the standard F7/ePM1, giving a meaningfully higher level of fine particulate and allergen capture for severe allergy or asthma sufferers. Check your specific Q-model's fan capacity first, since HEPA-grade media has higher airflow resistance than standard filtration.
Do Zehnder ComfoAir Q350, Q450 and Q600 units use the same filter size, or does it change by model?
Filter dimensions scale with the Q-series model number, so a Q350 takes a different size than a Q450 or Q600 even though all three use the same M5(ePM10)/F7(ePM1) filtration logic. Always confirm your exact Q-model on the front panel before ordering rather than assuming size compatibility across the range.
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 recommend for ComfoAir units?
Zehnder ComfoAir units are typically fitted with two filter classes as standard:
- M5 (ePM10) extract filter
- F7 (ePM1) supply filter
This reflects the brand's strong focus on Passive House-grade air quality — many allergy-sensitive households upgrade further where the housing supports higher-grade filtration.
How do I find the correct replacement filter for my Zehnder ComfoAir unit?
The exact ComfoAir model — such as Q350, Q450 or Q600 — is printed on the unit's front panel and is the fastest way to match the correct filter set in our catalogue. If the label is missing, measuring the extract and supply filter panels directly will identify the right size just as reliably.
