Clinical Study Summary – Kaltech Photocatalyst & Nihon University School of Medicine
In collaboration with the Division of Hematology and Rheumatology at Nihon University School of Medicine, Kaltech Corporation conducted a clinical study to evaluate the real-world effectiveness of its photocatalytic sterilization and deodorization device . The objective was to determine its potential in preventing infectious diseases , particularly among vulnerable patients such as the elderly and individuals with weakened immune systems.
The device was installed in multiple hospital rooms at Itabashi Hospital , and infection-related data were collected one month before and after installation. The study focused on fever-related neutropenia (FN) , a critical condition caused by a significant drop in white blood cells, which increases susceptibility to infection. Results showed a notable decrease in FN cases—from 12 to 3 patients , with a particularly significant drop among elderly patients aged 65 and older (from 10 to 2 ). These results were statistically significant , indicating that the device may play a key role in reducing the risk of infection.
Previously, Kaltech had demonstrated the device's effectiveness in controlled environments, notably showing that the COVID-19 virus was rendered undetectable after 20 minutes of exposure in a sealed test chamber. This clinical study marks an important step by confirming the device's efficacy under actual usage conditions .
Dr. Kazuhide Iizuka, who oversaw the study, highlighted that reducing infections could help shorten hospital stays and lower treatment costs , and emphasized the device's potential use in nursing homes and elderly care facilities .
In conclusion, the study supports the photocatalytic device's real-world effectiveness in infection control and suggests promising applications in healthcare settings to protect high-risk populations .

Clinical Study Summary – Kaltech Photocatalytic Device & Nihon University – Faculty of Medicine
In collaboration with the Division of Hematology and Rheumatology at Nihon University College of Medicine, Kaltech Corporation conducted a clinical study to evaluate the real-world effectiveness of its photocatalytic sterilization and deodorization device. The goal was to determine its potential in preventing infectious diseases, particularly in vulnerable patients such as the elderly or immunocompromised.
The device was installed in several rooms at Itabashi Hospital, and infection-related data were collected one month before and one month after installation. The study focused on febrile neutropenia (FN), a critical condition caused by a significant drop in white blood cells, increasing the risk of infection. The results showed a notable decrease in FN cases: from 12 to 3 patients, with a particularly marked decrease in patients aged 65 and older (from 10 to 2). These results are statistically significant, suggesting that the device could play a key role in reducing the risk of infection.
Previously, Kaltech had already demonstrated the effectiveness of its device in a controlled environment, notably by proving that the COVID-19 virus became undetectable after 20 minutes of exposure in a sealed test chamber. This clinical study represents a major breakthrough, confirming the effectiveness of the device in real-world conditions.
Study supervisor Dr. Kazuhide Iizuka noted that reducing infections could help shorten hospital stays and reduce treatment costs, while highlighting the device's potential for use in nursing homes and elderly care facilities.
In conclusion , the study supports the effectiveness of the photocatalytic device in combating infections in real-life conditions and suggests promising applications in medical settings for the protection of high-risk populations.
