Test Report

Air purifier tested

The air in our homes can be polluted in many different ways and make us ill: From fine dust and pollen to pollutants from paints and adhesives to pathogens such as coronaviruses. The best air purifiers tested significantly reduce the concentration of these particles and gases. But not all of them achieve this. The effectiveness of the filters often decreases over time. Some devices also cost money in the long term because they consume a lot of electricity or changing the filter is expensive. Our comparison will help you find a good and affordable air purifier.
