Genuine filter set for the high-capacity Flexit Nordic S7 heat recovery unit. This set includes two high-efficiency filters (F7 grade or F7/F8 combination) specifically designed for the patented Stage Wheel heat exchanger. The 96 mm deep filters ensure maximum air filtration for large homes and protect the Nordic S7's advanced technology.
Advantages of the Nordic S7 Filter Set
Healthy Large-Scale Home
For the Nordic S7 unit, designed for homes up to 450 m², filtration quality is a priority. Flexit F7 filters protect your lungs from microscopic outdoor pollution.
Long Life and Quiet Operation
Regular filter replacement is a prerequisite for quiet operation. Clogged filters increase aerodynamic noise and strain the ventilation system.
When and Why to Change Nordic S7 Filters?
The manufacturer recommends filter replacement every 6 to 12 months. The 96 mm deep filters have a high dust capacity, but in dusty areas (heavy traffic, construction), more frequent checking is advised.
Your unit will notify you of the need for replacement via the controller or the Flexit GO mobile app.
