CAP is an action that brings about the possibility of living in an environment with constant fresh air everywhere by allowing outdoor air to enter indoor spaces throughout an entire area.
By maintaining indoor CO₂ levels below 1,000 ppm through ventilation, the indoor air contaminated with aerosols and CO₂ is replaced with fresh outdoor air.
If CAP is practised everywhere, infection of the COVID-19, influenza, cold and other respiratory infectious diseases will come to an end, and a healthy life without infections will be realised.

CO₂ Monitor and Ventilation

CO₂ below 1,000 ppm: Ventilation is sufficient. The air in the room is clean. The risk of airborne infection is low.
CO₂ exceeds 1,000 ppm: Ventilation is insufficient. The risk of airborne transmission is high.

Fresh air : Carbon dioxide (CO₂) concentration in the air is less than 1,000 ppm.

Keep the CO₂ concentration below 1,000 ppm by the indoor ventilation and always breathe fresh air.
Keep indoor fresh air by ventilation, the virus is expelled to the outdoors and disappears.

Health problems caused by CO₂ (drowsiness, headaches, fatigue, tinnitus, productivity - decision making/problem solving, learning, etc.) are no longer a concern in fresh air.
