Filter Class Comparison

Choosing the right filter class depends on your air quality needs and local conditions. Here is how the available options compare:

• M5 (ePM10 55%): Captures medium-sized particles down to 10 μm. Suitable for areas with moderate outdoor air quality.
• F7 (ePM1 70%): Captures ultra-fine particles down to 0.3 μm. Recommended for urban environments, areas with high traffic, or when superior indoor air quality is a priority.

For Flexit UNI 4 units, the F7+F7 set offers the highest level of filtration and is recommended for most residential and commercial applications.
