All available Thermelec filters
One set often fits several units. The compatible models are listed under each one.
Replacing the filters of a Thermelec unit
Thermelec heat recovery units have one filter on the supply air and one on the extract air. Replace them every six months, check them every three. Our sets match the size and frame of each model's original filter, in ISO Coarse 75% (G4) or ISO ePM1 65% (F7).
Compatible product. Not manufactured or sold by the brand named. Brand and model names are used solely to indicate compatibility.
Frequently asked questions
How do I know which filter fits my Thermelec?
Open your model's page: it lists the number of filters, their dimensions and their frame. Compare with the filter in place if in doubt.
Can I fit an F7 on both sides?
The F7/F7 set exists for every model. Pressure drop is higher: keep that choice for a unit that accepts it and watch the filter indicator.
Would you rather we took care of it?
In Brussels, Brabant and Hainaut we replace the filters during your unit's service visit, with a written report.
