Standard Filters
Particles as small as a few microns are filtered by means of attracting pollutants by electrostatically charged fibres. Synthetic fibres are not very hygroscopic, which means water does not cause cabin filters to deform. The filtration barrier in the cabin filters is made of fully synthetic non-woven fabric.
Activated Carbon Filters
The advantage of activated carbon filters is that they trap not only solid particles, but also harmful gases such as sulphur dioxide, nitrogen dioxide, carbon monoxide, and ozone. Through adsorption, activated carbon adsorbs unpleasant odours, preventing them from entering the cabin from the outside.
| Standard: | Around 98% for 5-100 micron particles (dust, pollen). |
| High-Efficiency: | Captures smaller particles; some claim 99%+ at 0.3 microns (PM2.5). |
| Material: | Paper/Multi-fiber |
| Material: | Activated Carbon |
