Filter set F7/F7 Nordic S2/S3 for Flexit Nordic S2 and Nordic S3 heat recovery units. Designed to maintain clean indoor air, protect the heat recovery unit, and ensure reliable, energy-efficient ventilation performance.
• Filter set including 2 × ISO ePM1 55% (F7) supply and extract filters (272 × 166 × 48 mm).
• Designed for Flexit Nordic S2 and Flexit Nordic S3 heat recovery units.
• Helps maintain a healthy indoor climate with clean, fresh, filtered air while supporting efficient ventilation system performance.
FILTER CLASS According to ISO 16890-1:2016 / EN779:
• Supply filter: ISO ePM1 55% (F7) – improves indoor air quality by filtering incoming outdoor air.
• Extract filter: ISO ePM1 55% (F7) – protects the heat recovery unit by reducing dust accumulation inside the ventilation system.
FILTRATION PERFORMANCE
• Filtration efficiency: ISO ePM1 55%.
• Captures approximately 55% of PM1 fine particles, including bacteria, smog, tobacco smoke particles, combustion dust, spores, wildfire particles, and other fine airborne pollutants.
The filter set performs two essential functions:
• Supply filter – cleans incoming outdoor air to improve indoor air quality and create a healthier living environment.
• Extract filter – protects the heat recovery unit by reducing dust build-up, helping maintain efficient airflow and extending system lifespan.
Regular filter replacement every 3–6 months helps maintain optimal ventilation efficiency, lower energy consumption, and consistent indoor air quality.
