Description
The Ventilair Calma F7 Filter is a replacement or filtration upgrade for compatible Calma heat recovery ventilation units. Its finer media is designed to capture a greater proportion of small airborne particles before outdoor air is supplied to the building.
Each Calma unit uses two of these filters. They should be fitted and replaced together so that the system sees consistent resistance across the two filter positions and maintains the intended airflow balance.
F7 filtration can be useful in urban locations, roadside properties and other environments with higher external dust or particulate levels. As the filters load with captured material, airflow resistance increases, so regular inspection and timely replacement are important.
