Have your air purifiers professionally tested
An air purifier can reduce chemical substances, fine dust and microbiological pollution in the air. Exactly which parameters from the air are reduced depends on the device. A device that is not properly designed can form harmful by-products, so it is important to follow this up.
VITO has more than 30 years of experience in testing air purification systems in industry and in indoor air quality measurements. With the combination of these expertises, a new 30 m³ test chamber has been built to comprehensively test air purifiers.

Our measuring approach for air purifiers
An air purifier can be tested in the lab under ideal conditions in a 30 m³ test chamber or in a tunnel setup. This involves providing a continuous supply of air with known pollutant concentrations and determining the reduction efficiency per component and the possible by-products formed.
After an initial test in the lab, the performance of the air cleaner can be measured on site.
