In a test where human coronavirus was attached to 'additive-free housing original plaster,' it was found that '100% inactivation (death) of human coronavirus occurred within 5 minutes.'
In this inspection, we conducted tests by applying human coronavirus (HCoV-229E) to our original additive-free plaster. The results showed that the human coronavirus was completely inactivated five minutes after application. (This test used "human coronavirus," which has 90% genetic similarity to the novel coronavirus. Additionally, the test was conducted using "test pieces" and does not indicate the performance of the building.) Furthermore, according to the National Institute of Allergy and Infectious Diseases in the United States, when human coronavirus adheres to plastic or stainless steel, its survival period is said to be more than three days. Taking this perspective into account, it was confirmed that our original additive-free plaster possesses beneficial properties. *While our plaster has the ability to inactivate human coronavirus, it does not guarantee infection prevention.

basic information
The test was conducted by the Certified NPO Biomedical Science Research Association. "The Original Lime Plaster for Additive-Free Houses" Mechanism of Inactivating Human Coronavirus We have illustrated and provided easy-to-understand examples of why the Original Lime Plaster inactivates (kills) human coronavirus when it adheres to it. A person's cough releases about 50,000 human coronaviruses in a single instance, while a sneeze releases about 100,000 human coronaviruses. The range of droplets is said to be approximately 2 meters.

Applications/Examples of results
A space surrounded by traditional plaster creates a gentle atmosphere for people. Our original additive-free plaster is a safe and secure wall material that does not use chemical adhesives. Additionally, its excellent moisture-regulating properties help suppress condensation, and the unique design of plaster walls creates a space that never becomes boring. Additive-Free Housing primarily focuses on newly built single-family homes, but we also carry out renovation work and construction for stores, kindergartens, clinics, and hospitals. Additive-Free Housing aims to provide nationwide support through a dealership system. Currently, there are 171 dealerships, but there are still areas that are not covered. The dealership system was initiated to establish a framework for building "Additive-Free Housing" across the country. Unlike a typical franchise, each dealership has a high degree of freedom. The headquarters of Additive-Free Housing works to increase the number of new dealerships and introduces interested construction companies to become dealerships.

Company information
For many years, we have researched whether it is possible to build houses without using harmful chemicals such as synthetic adhesives and chemical building materials. By carefully selecting natural materials for construction and striving to minimize the use of chemicals, we have achieved the ultimate in additive-free living, leading to the birth of "additive-free houses." We believe that homes should coexist with nature, and we aim to build houses that anyone can live in comfortably and safely for 100 years.
