N2 - Five portable air cleaning technologies including one new technology were evaluated to find their effectiveness in removing ultrafine particles. Measurements were carried out both in a duct and in a test room. The results showed that the technologies that use/create ozone to clean air can increase the ozone level significantly in the room. Moreover, they can cause generation of ultrafine particles and consequently increase ultrafine particle concentration in the room. The study suggests using a mechanical filter with low pressure drop as a recommended air cleaning technology in order to remove ultrafine particles efficiently from the indoor environment.
