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.

自從安裝了你們AIRO2 空氣清新機後,平時每天久不久在家打噴嚏的情況消失了,加上每天在家也嗅不到外边附近食館傳入屋的烹調氣味。它能為我們一家人帶來清新空氣,使居住環境更舒適愜意,它真是一流的高科技產品。我本人感覺空氣很清新又沒有塵,真是養生之道。多謝!

本人是一位長者,住近銅鑼灣,有氣管敏感。由朋友介紹,用了AIRO2, 當天晚上睡得安寧,喉嚨無平時干,同時痰少了些。
