Pollen, dust or fine traffic particles? Compare ePM10 and ePM1 with real ZenAero filters, particle illustrations and sets for your ventilation unit.
Pollen and dust, or fine particles from traffic as well? ePM10 and ePM1 meet different filtration needs. See what changes in the air entering your home and find the right filter for your ventilation unit.
ePM10 helps reduce pollen, spores and road or mineral dust. For finer filtration of particles from smog, traffic and combustion, look for ePM1. Choose a compatible size and a class suitable for your unit.
The label identifies the particle fraction used to assess the filter. PM10 includes particles up to 10 micrometres; PM1 refers to finer particles up to 1 micrometre. PM10 also includes fine particles, so an ePM10 filter does more than catch visible dust.
The percentage is the declared efficiency for that fraction. The ZenAero examples below are ePM10 60% (M5) and ePM1 60% (F7): the two 60% figures refer to different particle fractions.
An ePM10 filter helps reduce pollen, mould spores, PM10 and road or mineral dust. It offers balanced filtration when these are the main particles you want to reduce.
Example: filters for Vortice HRI 200 →
M5 + M5 set: two ePM10 60% filters, 227 × 212 × 24 mm.
An ePM1 filter also reduces fine PM1 / PM2.5 particles and particles from traffic and combustion, alongside pollen and spores. It is particularly useful near busy roads and during the heating season.
Example: filters for Zehnder ComfoAir Q →
F7 + G4 set: ePM1 60% for supply air and ISO Coarse for extract air, 499 × 158 × 22 mm.
Particle images are illustrative. Vortice and Zehnder are examples of compatible units; the comparison concerns ZenAero filter classes.
ePM10 can be a good choice when outdoor dust and pollen are your main concern and your unit uses this class.
For finer filtration of incoming air, choose a compatible ePM1 filter to reduce smaller particles associated with smog and combustion.
Here, the filter mainly protects the unit from household dust. Depending on the model, the class may be ePM10 or ISO Coarse.
Manuals often use the older labels: F7 for fine filtration, M5 for intermediate filtration and G4 for coarse particles. The products shown here declare ePM1 60% for F7, ePM10 60% for M5 and ISO Coarse for G4. There is no universal conversion between the old and new classifications; read the class on the product.
Some units use two filters of the same class. Others pair a fine supply-air filter with a different extract-air filter. Here are three examples.
| Unit model | Filter dimensions | Supply air | Extract air |
|---|---|---|---|
| Aerauliqa QR280A / E / M / PH | 250 × 183 × 21 mm | ePM1 60% (F7) | ePM10 60% (M5) |
| Aerauliqa QR180A / M / PH, QR200, QR230E | 200 × 200 × 46 mm | ePM1 60% (F7) | ISO Coarse (G4) |
| Zehnder ComfoSpot 50 | 182 × 123 × 20 mm | ePM1 60% (F7) | ISO Coarse (G4) |
Check the filters every 4–6 months, and sooner during periods of heavy pollen, traffic or dust. Follow the unit’s filter alert and maintenance instructions. Replace disposable filters when loaded or damaged; clean filters help maintain good airflow.
