Public Transportation

Insufficient fresh air supply in high-speed rail stations, subway stations, bus terminals, or airport terminals directly causes a rapid decline in indoor air quality in these already enclosed spaces. Moreover, the ventilation capacity of central air conditioning systems not only fails to thoroughly solve air pollution problems but also introduces outdoor pollutants indoors. Waiting passengers often experience discomfort symptoms such as dizziness and chest tightness due to air pollution. To provide a comfortable waiting environment for passengers and staff, the use of professional air purification devices to improve indoor air quality is essential.

Airports

Exhaust emissions from aircraft engines and airport ground service vehicles enter the terminal building through HVAC systems, exacerbating indoor air pollution. Through efficient purification of gaseous molecular pollutants, EcoKeeper improves air quality in the terminal and effectively reduces HVAC system operating costs.

High-Speed Rail & Train Stations

The waiting rooms of high-speed rail and train stations are public health spaces shared by passengers and staff. EcoKeeper removes carbon monoxide, carbon dioxide, and irritating odors from waiting rooms, preventing the spread of infectious diseases transmitted through air as a medium for bacteria and viruses. It effectively safeguards the physical and mental health of passengers and railway staff, while reducing HVAC system operating costs.

Subway Carriages

Subway carriages have limited space and high passenger density. Odors released through the metabolism of passengers and crew — breathing, sweating, burping, and flatulence — along with food odors and foul smells from restrooms, mix together, resulting in stale and polluted air inside the carriages. By improving air quality, EcoKeeper provides passengers with a convenient and comfortable riding experience while safeguarding the health of crew members.

EcoKeeper helps you eliminate all types of odors and create a pleasant environment. Through a chemisorption process, harmful gases are converted into harmless solid salts and stored within the material to remove pollution. It efficiently purifies over a thousand harmful gaseous pollutants — including formaldehyde, carbon dioxide, ozone, and sulfur dioxide — thoroughly eliminating annoying odors.
