Genuine filter set for the Flexit Nordic S4 heat recovery unit. This premium set includes two high-efficiency F7 grade compact filters (ePM1 55%) designed for both supply and exhaust air. The filters effectively capture fine particles, pollen, and industrial dust, ensuring a healthy climate in your home and protecting the sensitive heat recovery system.
Key Benefits of the Nordic S4 Filter Set
Health and Comfort
Genuine Flexit filters filter air at a microscopic level. They are a must-have for families with children, allergy sufferers, and asthmatics, as they remove respiratory triggers from the indoor environment.
Optimal Operation
Regular filter replacement is a prerequisite for the long life of the heat recovery unit. Clean filters ensure quiet fan operation and maintain high heat transfer efficiency in the rotary heat exchanger.
Filter Replacement Interval
To ensure peak indoor air quality, Flexit recommends replacing both filters at least once a year. In case of high pollution in the vicinity (construction, agriculture, heavy traffic), we recommend checking and replacing every 6 months.
Using the Flexit GO mobile app, you can conveniently monitor the contamination level and receive automatic notifications when service is required.
