In its October health risk notice, the Tianjin CDC rated the risk of respiratory infectious diseases at four stars and named the venues directly: schools, elderly care facilities and medical institutions must guard against cluster outbreaks. The Henan CDC was even more specific — "as the weather turns cooler in autumn and the day-night temperature difference widens, together with more indoor activity and reduced ventilation, this is the high season for respiratory infectious diseases" — and also warned of rising risk in crowded places such as railway stations, airports, scenic spots and shopping malls.
Influenza often brings high fever, headache and general aching; Mycoplasma pneumoniae typically causes an irritating dry cough and is more common in children and adolescents. The protective advice given in different regions is highly consistent: get vaccinated, wash your hands frequently, wear a mask properly, and — maintain ventilation.
Problem one: the season does not allow it. Opening windows in autumn and winter lets cold air pour in, drops the room temperature and drives up energy consumption. For wards that need a stable temperature, meeting rooms that need a quiet environment, and lobbies that cannot interrupt the flow of visitors, "open the windows two to three times a day for at least 20 minutes" works on paper but is very hard to carry out on site.
Problem two: the space cannot wait. In places such as hospital lobbies, waiting areas, canteens and large meeting rooms, openings are limited while people keep moving through. When the air exchange rate is insufficient, droplets and aerosols stay suspended longer, and crowded areas more easily become a breeding ground for transmission.
In other words, what public spaces really lack is not a reminder, but a continuous air treatment capability that does not depend on human effort and is not limited by the weather.
(1) Concealed ceiling installation, low barrier to deployment
The recessed ceiling design keeps the main unit above the ceiling panel. It takes up no floor or aisle space and does not disrupt the interior style, so it can be deployed quickly in both new-build and retrofit projects.
(2) Wide-angle circulating airflow, no purification or disinfection blind spots
Top air intake combined with four-side angled air discharge creates a wide-angle circulating airflow that draws air from every corner of the space into the treatment cycle, instead of merely moving air around the unit itself.
(3) Active disinfection plus passive interception
A DBD plasma disinfection core works together with a composite filter: the plasma is released actively and acts on both air and surfaces, delivering a bacteria and virus inactivation rate of 99.99%, a PM2.5 removal rate of 99.7% and a TVOC removal rate of 99.99%, with a plasma density of 3.8×1019/m³.
(4) High airflow, low noise, ready for building management systems
It runs quietly at a high airflow of 1,020 m³/h, suitable for full-area air treatment in medium-to-large spaces, and can be connected to a building management system with operating status available for monitoring and review.
Medium-to-large public spaces including hospitals, hotels, large conference rooms, public lobbies, canteens and civil (biological) laboratories.
Respiratory infectious diseases have their own cycles, and personal protection will always be the first line of defence. Another thing we can do is to prepare every place where people gather a little more thoroughly than in previous years — not necessarily to be seen, but always at work.
