Where do ultrafine particles come from?
Traffic
Exhaust fumes, brake discs and tyre wear produce ultrafine particles along motorways and busy roads.Wood smoke
Wood burning is a major source of fine dust and ultrafine particles in Dutch neighbourhoods.Air traffic
Around airports such as Schiphol, ultrafine particles are measured structurally.Fine dust vs. ultrafine particles
Fine dust (PM2.5 / PM10) is an umbrella term for small particles. Ultrafine particles (UFP, < 0.1 μm) are a subset of that — the smallest fraction, comparable in size to a virus. It's precisely because of their size that UFP calls for separate attention in the indoor climate.

Charged particles can settle faster
With ionization, airborne particles receive an electrical charge. This lets them attach to a collector or to surfaces. This is a different technique from physical filtering; regular cleaning and good placement remain important.

Frequently asked questions
Fine dust (PM2.5 / PM10) is an umbrella term for small particles. The RIVM defines ultrafine particles (UFP) as particles smaller than 0.1 micrometre. Possible health effects and long-term exposure are still being researched.
That depends on the model, the technology used and the test conditions. Filter models and ionization models work differently. That's why we only publish product-specific performance once the corresponding test report and measurement method are available.
Falling water breaks up into tiny droplets and naturally generates negative ions in the process — the same principle ionization air purifiers imitate. Those same negative ions cause airborne particles to clump together, so they settle faster and the air feels cleaner.
No. Ventilating remains the basis of a healthy indoor climate. Air purification is an additional step against airborne particles, not a replacement for fresh air from outside.
