With the increasing demand for evacuation facilities due to climate change, pandemics, and geopolitical risks, many ventilation systems are manufactured overseas and there are concerns about supply and maintenance. The AT-Barrier is a CBRN-compliant high-performance filter that can be used not only in times of disaster but also for air purification during normal times.




CBRNE-compliant units
AT Barrier 150 is, CBRNE (chemical, biological, radioactive, nuclear, and explosive) The AT Barrier 150 is equipped with a unique unit designed to respond to CBRNE (Chemical, Biological, Radiological, Nuclear, and Explosive). It effectively purifies contaminated air during emergencies.
Peace of mind not only in emergencies but also in everyday life
AT Barrier's performance is not limited to disasters, Odors and allergens in the air in everyday life, PM2.5 and other particulates and gases in the air. It also functions as a permanent air purification system that can be used safely even in normal times.

A cyclone separation mechanism and pre-filter remove coarse particles, and a HEPA filter filters fine particles with high precision. Finally, a chemical filter adsorbs toxic gases and odor components. Step-by-step filtering addresses a wide range of air risks, from disasters to everyday life. It provides a safe and clean air environment.

chemical filter
Special military grade chemical filters are used to filter out gaseous toxic substances such as hydrogen cyanide, hydrogen cyanide, and VX gas. VOCs, odors, and other gaseous toxic substances in addition to toxic gases such as hydrogen cyanide and VX gas The filter physically and chemically adsorbs and removes gaseous toxic substances such as VOCs and odors as well as toxic gases such as hydrogen cyanide and VX gas at the molecular level.
HEPA Filter
Medical grade high performance that removes at least 99.971 TP3T of particulates 0.3 μm and larger HEPA filter is adopted. Viruses, bacteria, mold spores, and PM2.5, PM2.5, and even particulate radioactive materials (a cause for concern in the event of a nuclear disaster).
Pre-filter
Captures coarse particles such as dust, hair, pollen, and fiber debris in the air at the initial stage. Highly durable filter. Substantially improves filter performance and life at the later stages.
Cyclone separation mechanism
Centrifugal force physically removes heavy particles, sand, volcanic ash, and pollen from the air.

- Private shelters for individuals
- Disaster shelters for municipalities and public facilities
- Evacuation centers (schools, hospitals, government buildings)
- Corporate BCP bases (data centers, manufacturing, financial institutions)
- Temporary medical clinics and waiting areas at medical and welfare facilities



In shelters and enclosed spaces, odors such as sweat, excrement, and putrefaction can accumulate, increasing psychological stress and hygiene risks.
AT Barrier 150 is also highly effective in removing odors generated in closed spaces for long periods of time. In fact, we verified the removal performance against typical odor components such as sweat, excretion, and putrefaction odors in a chamber designed for evacuation shelters and shelter environments.



Hydrogen sulfide is a peculiar malodorous substance, like rotten eggs, that is produced when wastewater or sewage decomposes.
Increased concentrations may affect the respiratory and nervous systems.
AT-Barrier150 was highly effective in reducing the concentration of hydrogen sulfide by more than 90% within about 30 minutes of the start of the test.


Methyl mercaptan is a strong malodorous substance that is produced during food waste, wastewater, and food spoilage. In a demonstration test, AT-Barrier 150 removed more than 991 TP3T of methyl mercaptan in 40 minutes.


Acetic acid is the substance responsible for the sour odor produced by sweat, body odor, and decaying food, and can cause discomfort and mental stress in enclosed evacuation spaces. In enclosed evacuation spaces, it can cause discomfort and mental stress. AT-Barrier 150 has been shown to significantly reduce acetic acid concentrations by more than 70% in just 10 minutes.


Isovaleric acid is a substance that causes strong unpleasant odors resulting from sweat and steamed shoes. In a closed environment, the odor tends to accumulate particularly easily and can cause a psychological burden.


Ammonia is a substance with a stinging odor derived from sweat and excretions. In enclosed environments for long periods of time, there are potential hygienic risks, such as eye and respiratory irritation, etc. Demonstrations of AT-Barrier 150 quickly and effectively reduced ammonia concentrations, which are considered very difficult to remove.
