Tests by Smart Air show that restaurants typically have the worse air quality than outdoor air. A large reason is that cooking in restaurant kitchens produces large amounts of PM2.5 pollution.
The recommended approach to improving air quality in restaurants is to install extractor fans with filtration in the kitchens. This helps reduce the chances of polluted air produced during cooking from reaching the restaurant dining area.
Air purifiers can also be used to clean the air in restaurants and improve air quality for diners when poor air quality is a problem. It is recommended that air purifiers be they be placed at a location in the dining area that is close to the kitchen. This maximises the effectiveness of the air purifier by ensuring any polluted air escaping from the kitchen can be filtered by the air purifier before it reachers diners.
