ALT Educational graphic explaining PM2.5. It states that PM2.5 means particulate matter measuring 2.5 micrometres or smaller. An illustration compares the tiny particles with a human hair and shows examples including combustion particles, organic compounds, and metals. Text explains that these particles are tiny solids or liquid droplets suspended in air.

ALT Graphic explaining sources and health significance of PM2.5. Listed sources include vehicle exhaust, wood burning, construction dust, wildfire smoke, cooking, candles, incense, and outdoor dust. The graphic explains that PM2.5 can travel deep into the lungs and is associated with adverse health effects, with particular concern for children, older people, and people with respiratory conditions. A PM2.5 monitor reading 37 is shown beside flowers and a lit candle.

ALT Infographic titled “Three ways to breathe less PM2.5.” It recommends: 1) measure it with a monitor, 2) cut it at the source by using an extractor while cooking and reducing candles and incense, and 3) filter it with an air purifier. A call-to-action invites viewers to find the right fit for their space.

ALT Promotional graphic from Smart Air encouraging schools and parents to address indoor air quality. Large text on the left reads: “Parents: Put indoor air quality on the next PTA agenda.” Below, it says: “Teachers: Check morning AQI, adopt air purifiers in classrooms, and keep doors closed.” On the right, a teacher stands at a whiteboard in front of several seated adults, writing “AQI TODAY” with an AQI value of 156 and the message “Unhealthy for Sensitive Groups.” The scene resembles a classroom or meeting setting, reinforcing the focus on air quality awareness in schools.

ALT Infographic titled “The 20 UK Cities Where You’re Indirectly Smoking the Most Cigarettes.” It explains that cities with higher average PM2.5 air pollution are associated with more cigarette-equivalent exposure. Liverpool ranks first, with 171 cigarettes per year, followed by Worthing (166), Northampton (158), Manchester (149), Bournemouth (148), Ipswich (146), Bolton (133), Kingston upon Hull (131), Swansea (131), Cardiff (131), London (129), Nottingham (129), Luton (128), Portsmouth (126), Bristol (124), Plymouth (123), Sheffield (123), York (123), Belfast (121), and Birmingham (121). The graphic notes that the figures are based on 2024 PM2.5 data and Berkeley Earth’s calculation of cigarette-equivalent exposure. An illustration of lungs and smoke appears at the top right.
