    Filters in the ePM10 class must capture at least 50% of PM10 particles (0.3–10 μm) during testing. For instance, a filter rated as ePM10 55% captures more than 55% of PM10 particles. The term "ePM" stands for Efficiency of Particulate Matter.

    These filters are especially useful in areas with high PM10 pollution and can trap allergens like pollen, improving indoor air quality.

    Filters in the ePM1 class must capture at least 50% of PM1 particles (0.3–1 μm) during testing. For example, a filter rated as ePM1 70% captures more than 70% of PM1 particles. The term ePM stands for Efficiency of Particulate Matter.

    These filters effectively remove fine solid particles, ensuring healthier indoor air. They are the most efficient filters in the ISO 16890 classification.

    An M5 filter helps protect your ventilation system—especially the heat exchanger—from clogging, while also filtering out PM10 particles common in many European cities. Positioned between G4 and F7 filters, the M5 offers more effective filtration than G4 with lower energy use and a longer lifespan than F7.

What is an M5 Filter? M5 filters belong to the "medium filtration" category, ideal for capturing medium-sized particles (over 5μm) to improve indoor air quality. These filters are particularly useful in areas with high PM10 particle pollution and can capture allergens like pollen.

Why Choose an M5 Filter? An M5 filter helps protect your ventilation system—especially the heat exchanger—from clogging, while also filtering out PM10 particles common in many European cities. Positioned between G4 and F7 filters, the M5 offers more effective filtration than G4 with lower energy use and a longer lifespan than F7.

What Particles Does an M5 Filter Capture? M5 filters are effective at capturing:

  • 50-70% of PM10 particles (e.g., dust, pollen, mold spores)
  • Up to 25% of PM2.5 particles (e.g., combustion particles)

These filters are a great choice for managing dust, allergens, mold spores, and pet dander.

Where Are M5 Filters Commonly Used? M5 filters are typically found in:

  • Supply air filters in many air handling units (AHUs), such as Oxygen, Komfovent, and others.
  • Occasionally, in exhaust air filters in units like Komfovent, Lindab, Systemair, and 2VV, although exhaust filters generally don’t affect indoor air quality.

When Should You Choose an M5 Filter? Consider an M5 filter if:

If you’re in a city center, near main roads, industrial zones, or where solid fuel is used for heating, an F7-F9 or activated carbon filter might be a better choice.

M5 Filters and the ISO 16890 Standard M5 filters correspond to the ISO 16890 standard, with Coarse 90% to ePM10 70% efficiency.
