Poor outdoor air quality, unpleasant temperature, high humidity, mosquitoes nuisance and traffic noise have compelled schools in Hong Kong to convert naturally ventilated classrooms to air-conditioned classrooms.
An air-conditioned classroom does not block off outdoor air pollutants or bring in fresh air from the outside.
In fact, most air-conditioned classrooms contain air pollutants that exceed the ASHRAE CO2 standard (1000 ppm) and the WHO PM 2.5 standard (10/25 ug/M3).
Poor indoor air quality SBS (sick building sydromes) in classrooms could increase risks of infectious diseases among students, such as respiratory problems, skin irritation, fatigue and difficulty in concentration.
The unique design of AIRO2 Fresh AirFlow Purifier Model W450 ensures an adequate supply of purified fresh air and significantly reduces air pollutants in the classroom. Better air quality in the classroom may noticeably improve students’ health, reduce absenteeism and enhance academic achievement.
