Ventilation unit filters

Ventilation Unit Filters

Replacement filters for residential ventilation units and MVHR systems. ZenAero filters help keep incoming air cleaner, protect the heat exchanger and maintain efficient airflow throughout your ventilation system.

Our range includes compatible filters for popular ventilation brands and units, available in common filtration classes such as ISO Coarse, ePM10, ePM2.5 and ePM1. Depending on the filter combination, they help capture larger dust particles, pollen, fine dust and airborne pollution from outdoor air.

Every filter is made to the required dimensions for a secure fit in the compatible unit. Reliable sealing helps reduce unfiltered air bypass, while carefully selected filter media supports effective filtration without unnecessary resistance to airflow.

Choose the right replacement filter

• Check your ventilation unit model before ordering
• Choose ePM1 filtration where pollen and fine outdoor particles are a concern
• Choose ISO Coarse filters for basic protection against larger dust particles
• Replace both supply and extract-air filters when required
• Replace filters regularly to support air quality and system efficiency

Most ventilation filters should be replaced every 4 to 6 months. In areas with high pollen levels, traffic pollution, construction dust or frequent use of the system, more frequent replacement may be needed.
