On the afternoon of 8 October, Beijing's AQI reading reached 161, with PM2.5 as the primary pollutant and clearly elevated PM10 and ozone concentrations as well. Against Beijing's 2025 annual average PM2.5 concentration of 26.8 µg/m³ (AQI 85, "moderate"), this was a typical acute autumn pollution episode.
Then, on 9 October, the Ministry of Ecology and Environment gave a longer-term assessment at its regular press conference: under the influence of a super El Niño, air pollution control this autumn and winter will face a severe situation. The ministry will assess pollution episodes in advance and issue alerts in good time; the threshold for launching heavy-pollution weather alerts has been changed from "consecutive severe pollution" to "consecutive moderate pollution," and the alert coverage has been expanded from the Beijing-Tianjin-Hebei region and its surroundings to the whole country.
In other words, this winter's pollution episodes may arrive earlier, more frequently and more persistently. And the four main local sources of PM2.5 in Beijing — vehicles at 31.1%, coal combustion at 22.4%, industrial production at 18.1% and construction dust at 14.3% — show that this is not a problem that will be solved in a day or two.
When an air quality alert is issued, the advice is usually limited to a few points: stay indoors, wear a mask, close the windows, and turn on ventilation or purification equipment. But for spaces such as hospital lobbies, office meeting rooms, shopping mall atriums and school canteens, "closing the windows" only solves half the problem — the outdoor half. Where people are crowded together, fresh air supply is insufficient and openings are limited, particulate matter, TVOC and carbon dioxide will keep building up indoors.
Open the windows and you let outdoor pollution in; close the windows and you keep indoor pollution inside. This is the dilemma that medium-to-large public spaces face every autumn and winter.
(1) High airflow that keeps pace with large spaces
A circulating airflow of 1,020 m³/h and a particle CADR of 1,000 m³/h match the air volume of medium-to-large spaces such as hospital lobbies, shopping malls and transport hubs.
(2) Wide-angle circulating airflow, no blind spots
Top air intake combined with four-side angled air discharge creates a wide-angle circulating airflow that genuinely keeps the air moving throughout the space, rather than circling one piece of equipment.
(3) Adsorption and disinfection in one unit
A DBD plasma disinfection core paired with a composite filter delivers a PM2.5 removal rate of 99.7%, a TVOC removal rate of 99.99% and a bacteria and virus inactivation rate of 99.99%, with a plasma density of 3.8×1019/m³.
(4) Concealed installation, no space taken
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 overall interior style — particularly important for public lobbies where every square metre counts.
(5) Quiet operation, ready for building management systems
It runs quietly even at a high airflow of 1,020 m³/h, and can be connected to a building management system for centralised control, 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.
Improving outdoor air requires long-term treatment and regional coordination. The indoor layer, however, is something every building can decide to act on today. The autumn and winter pollution season has already begun — don't let "closing the windows" be the only answer.
