ALT Two side by side graphics about Long COVID from Air Support Project. The left graphic reads “Millions suffering. Infections and reinfections. No mitigations. No cure.” Large text says “CURE LONG COVID NOW,” with medical icons including an IV bag, syringe, and pills and a yellow lightning bolt behind the text. The right graphic shows a teal background with a ribbon labeled “Long COVID” and the words “Care for Long COVID” around it, with smaller text reading “Recognition, Research, Remedy.” Air Support Project’s logo appears at the bottom.

ALT Alt text: Infographic titled “How to Use Indoor CO2 Levels to Improve Air Quality” from Air Support Project. It shows four CO2 ranges: Natural outdoor air around 400 ppm; Low or Good at 400 to 700 ppm; Medium or Take Action at 800 to 1000 ppm; and High or Avoid above 1000 ppm, with notes about ventilation, health effects, infection risk, and reduced cognitive performance. Side text reads “COVID 19 Series, Part 2 of 7: The Hidden Dangers of Poor Ventilation. Understanding CO2 and its impact on COVID 19 infection risk.”

ALT Soft gradient background with enlarged orange rod shaped tuberculosis bacteria surrounding a centered white panel. Bold headline reads “Yes! We can end TB.” Supporting text honors World Tuberculosis Day and thanks teams advancing diagnosis, treatment, and prevention. Air Support Project logo appears below.

ALT Single graphic about Long COVID from Air Support Project. One side reads “Millions suffering. Infections and reinfections. No mitigations. No cure.” with large text “CURE LONG COVID NOW” and medical icons including an IV bag, syringe, and pills with a yellow lightning bolt behind the text. The other side shows a teal ribbon labeled “Long COVID” with the words “Care for Long COVID” and “Recognition, Research, Remedy,” plus Air Support Project’s logo.

ALT Chart titled “Poor Ventilation Increases Chances of Developing COVID 19.” The graph shows infection probability during a 15 minute conversation at different indoor CO2 levels from 400 to 2000 parts per million. Higher CO2 levels indicate poorer ventilation and correspond to higher infection risk. Three scenarios are shown. When neither person is masked, infection probability rises from about 30 percent at 600 ppm to 57 percent at 800 ppm, 74 percent at 1000 ppm, and about 92 percent at 1500 ppm. When both people wear surgical masks, risk rises from about 8 percent at 600 ppm to 19 percent at 800 ppm, 29 percent at 1000 ppm, and about 48 percent at 1500 ppm. When both wear N95 respirators, infection probability stays very low, about 1 to 3 percent across the range. The chart illustrates that higher CO2 levels, which signal poorer ventilation, are associated with increased infection risk. Source credited to Iwamura and Tsutsumi, 2023.

ALT Promotional graphic for Air Support Project, a 501 c 3 nonprofit organization. Top left features a purple banner with the Air Support Project name and logo in teal and purple. To the right, text explains that the organization believes clean air is a right and works to make affordable, science backed air quality solutions available for homes, classrooms, and care facilities so everyone can breathe fresh air. The center shows a large image of swirling colorful clouds in orange, yellow, pink, purple, and white tones, symbolizing air. Bottom left section titled “How you can help” lists: sign up for the newsletter, join virtual community events, volunteer your time, make a donation to fund projects, and follow on social media. Bottom right reads “Clean indoor air is human right” and includes the website [www.airsupportproject.com](http://www.airsupportproject.com/) on a purple bar.
