Kaltech Corporation (Headquarters: Chuo ku Osaka, President: Junichi Somei) collaborated with Riken (Japan's Institute of Physical and Chemical Research) and Nihon University School of Medicine to test the effectiveness of photocatalysts in suppressing the infectivity of the novel coronavirus SARS-CoV-2. The suppression effect was confirmed through research carried out at an advanced facility—designated Biosafety Level 3—in Nihon University.

Tests were conducted to verify the effectiveness of the photocatalyst in real life. Researchers used a commercially available sterilization deodorizer with photocatalysts to test the photocatalytic effect on novel coronavirus particles floating in an enclosed space.

Measurements of the virus titer were below the detection limit, confirming the infectivity suppression effect. These experimental results relate to the specific test environment. Results in other environments may differ.
