Compatible Zehnder Filters

Replacement Filters for Zehnder Ventilation Units

Find compatible replacement filters for Zehnder ventilation units, including popular ComfoAir Q 350, Q 450 and Q 600 MVHR systems. ZenAero filter sets are a reliable alternative to original filters, helping maintain clean incoming air, protect the ventilation unit and support efficient everyday operation.

Our replacement filters are available in common combinations such as ePM1 + ISO Coarse and ISO Coarse + ISO Coarse. The ePM1 filter helps capture pollen, fine dust and urban airborne particles from incoming outdoor air, while the ISO Coarse filter protects the extract-air side of the system from larger dust particles.

Each filter is made to precise dimensions for a secure fit in compatible Zehnder units. Reliable sealing helps reduce air bypass around the filter, while durable filter media provides effective filtration without unnecessary airflow restriction.
