This pack contains 2 x filters for use with the above heat recovery units. Each set contains x2 G4 filters 60% efficient

G4 filters are designed to capture large pollen spores, fog and coarse dust particles (≥10μm). This includes hair, mould & plant spores, pet dander, textile dust and skin flakes. The quoted efficiency rate for filtering these particles is >60%.

We also stock an alternative filter (Part No: CA155FIL) which is designed to filter the same particles but at a lower efficiency of > 45% offering a slight cost saving.

Please note, when replacing filters on your Greenwood heat recovery unit it is always necessary to also reset the filter change timer on the unit otherwise the service light will not go out.

These units work on a calendar timer basis and simply changing the filters will still present the same issue as the heat recovery unit has to be told by the user when the filters have been changed.
