Flexit Nordic CL3 / CL4 filter set F7+F7

We offer analogue, specially designed, high efficiency air filters for Flexit Nordic ventilation systems. They have a lifespan of approximately 6 months and are ideal for people who suffer from seasonal allergies.

These filters are distinguished by their high filtration efficiency. The F7 class filter, according to the ePM1 standard, achieves a filtration efficiency of up to 70%, which is higher compared to the original filters (55%) and most analogues. They thus effectively clean the air of smog particles and pollen.

The air-tight design ensures that the filter material fits snugly to the frame, preventing pollutants from entering the filter. The filter set includes the M5+F7 kit, which is strongly recommended by the manufacturer, and is packed in a cardboard box for long-term storage in a dry environment, providing a 2-year warranty if stored correctly.

Compared to other analogues, these filters offer:

1. Made of high quality synthetic filtering materials, which makes them more durable and efficient.
2. Tested according to the new EN ISO 16890 standard.
3. Provides high filtration efficiency, outperforming most other analogue filters.
4. A-frame made of thick, water-resistant cardboard that works even at 100% relative humidity.
5. High resistance to damage.

Compared to filters in a metal frame:

1. Ecological factor - made of easily recyclable cardboard materials.
2. Larger filter area and flexible frame for longer life.
3. Leak-proof construction and air-tight connection, preventing dust leakage.
