[Case Study] Tokyo Clinic Adopts BT-180H Ozone Generator | AIC

CASE STUDY: CLINIC

Tokyo Medical Clinic: Frontline Viral Infection Control
Driven by Medical Evidence

Installed Model: Tamura TECO BT-180H

As the threat of novel coronaviruses continues, medical institutions visited by many patients require higher quality hygiene management than ever before. This case study introduces why a medical clinic in Tokyo selected the “BT-180H" from among numerous sterilizers on the market, highlighting the background and the decisive factors behind their choice.

■ The Catalyst: Research Published by Fujita Health University

While the clinic director was closely monitoring news related to ozone technology, what caught his attention was a research presentation by Fujita Health University in Japan.

[Details of the Evidence]
On September 23, 2020, research announced by Fujita Health University (Professor Takayuki Murata) scientifically proved a 99.9% decontamination effect in novel coronavirus inactivation experiments using low-concentration ozone gas.

The “trust" and “track record" of the equipment actually being used at the Fujita Health University hospital site became the final deciding factor for its introduction.

24-Hour Peace of Mind: Switching Between “Occupied" and “Unoccupied" Modes

The installed “BT-180H" features two optimal modes for medical institution operations.

  • ✅ Occupied Mode: During the day when patients and staff are present, it keeps the space constantly clean with safe, low-concentration ozone.
  • ✅ Unoccupied Mode: At night or when the clinic is empty, it releases high-concentration ozone air to thoroughly sterilize (fumigate) every corner of the room.

Frequently Asked Questions (FAQ) Regarding Clinic Installation


It is extremely safe. In Occupied Mode, an internal sensor automatically controls the output to maintain a low concentration of ozone below the environmental standard (0.05 ppm) set by the Japan Air Cleaning Association. It can be used safely even in spaces with babies, the elderly, or those with allergies.

Daily maintenance consists only of cleaning the filter, and there is absolutely no need to replenish any chemicals. Since the only running cost is electricity (a few dollars a month), it is highly economical in the long run compared to sterilization methods that require consumables like hypochlorous acid.

Yes, the inactivation effect of ozone air on the novel coronavirus has also been confirmed in joint research with Nara Medical University. Based on verification data from multiple public institutions, equipment manufactured by Tamura TECO has been adopted as standard in ambulances and medical facilities nationwide in Japan.

In many cases, it is eligible for infectious disease control subsidies aimed at medical institutions. As the systems vary depending on the region and timing, AIC’s expert staff will provide support based on the latest information, including advice on preparing the necessary application documents.

Insights from AIC Specialists: The “Rationale" Chosen by Medical Institutions

As seen in this case, what doctors on the frontlines of medicine value most is not a manufacturer’s advertising slogan, but “evidence from public institutions such as universities." The BT-180H is one of the few devices whose performance has been recognized in academic papers through joint research with Fujita Health University and Nara Medical University. We confidently propose it not merely as an air purifier, but as “medical infrastructure" that guarantees 24-hour peace of mind.
