The Fight Against Air Pollution Gets Personal With Sleek New Masks
Go outside, close your eyes, and inhale. Do your lungs fill with fresh air – or are you taking a big deep breath of nasty fumes?
A new crop of tech startups is emerging to meet a growing demand for individualized clean air.
It depends, of course, on where you live – and for many people, the situation is worsening. According to a recent analysis by two Carnegie Mellon economists, particulate air matter pollution rose 5.5 percent in the U.S. between 2016 and 2018, resulting in almost 10,000 premature deaths.
Despite the urgency of the problem, there seems to be no indication that civic leadership will be protecting our air any time soon. The United States left the Paris Agreement recently, Brazil is still letting the Amazon burn and Australia lacks a national strategy for tackling air pollution, despite its recent catastrophic bushfires. China's deceptive coronavirus communication only underscores the point that safeguarding the public's health can take a backseat to politics and power.
But people still need to breathe, and now a new crop of tech startups is emerging to meet a growing demand for individualized clean air. At the recent Consumer Electronics Show, I saw futuristic masks, smart goggles and self-contained apparatuses promising to filter the bad air away.
Obviously, a dollar store surgical mask wasn't going to cut it anymore.
"We have seen a huge amount of interest and a growing awareness of the issues with masks and respirators," says AO Air co-founder Dan Bowden. "The more regularly someone wears a mask or a respirator, the deeper our Atmos solution resonates with them. Leading markets have been Korea, China and, unexpectedly, Thailand."
Lined up for a Summer 2020 launch, the AO Air filter fits across your mouth from ear to ear – kind of like Geordi LaForge's Star Trek: The Next Generation eye sensors, but across your jaw line. The translucent mask continually pumps cool air for about 5 hours per charge and will cost $350 USD.
"Soon, we'll have private schools selling themselves on the air quality of the building."
"There is a movement towards individuals taking control over their own health, but also we see a great movement towards individuals taking control over the impacts that they have on the wider world," Bowden says. "We believe that the deeper systemic change has always come from humans working together and not being reliant upon high powers."
Bowden says the company wants to help the individual citizen, clean up the public building air ("factories, hospitals, workplaces") and, most interestingly, collect pollution metrics data via the masks. "We are looking forward to hearing how this information can be used in creative ways," Bowden adds. It is yet unclear how the data will be shared and how proprietary the information will be for AO Air and its competitors.
Scientific artist Michael Pinsky is taking a more experiential approach to raise awareness of the problem. In 2017, he launched traveling pollution pods, these giant, interconnected rooms recreating the air quality of several cities from London to Los Angeles. His exhibit has been on near constant tour, hitting the New York Climate Action Summit, the recent COP25 in Madrid, and other major events.
When I visited, I could handle being in the New Delhi air quality pod for only about 20 seconds. It made my eyes water and burn.
"Now you have new, 8 – 10 million British pound houses being built with premium air systems," Pinsky says. "Soon, we'll have private schools selling themselves on the air quality of the building." I mention my own children, whose schools we selected based on ratings and rankings. I could easily see "indoor air quality" being another metric. Perhaps another lever of privilege.
Pinsky gives a wily chuckle.
"The legislators have to get on top of it – or air will be privatized like space or our schools," he says.
"Clean air is a right," he adds. "Everyone should have it."
If you look back on the last century of scientific achievements, you might notice that most of the scientists we celebrate are overwhelmingly white, while scientists of color take a backseat. Since the Nobel Prize was introduced in 1901, for example, no black scientists have landed this prestigious award.
The work of black women scientists has gone unrecognized in particular. Their work uncredited and often stolen, black women have nevertheless contributed to some of the most important advancements of the last 100 years, from the polio vaccine to GPS.
Here are five black women who have changed science forever.
Dr. May Edward Chinn

George B. Davis, PhD.
Chinn was born to poor parents in New York City just before the start of the 20th century. Although she showed great promise as a pianist, playing with the legendary musician Paul Robeson throughout the 1920s, she decided to study medicine instead. Chinn, like other black doctors of the time, were barred from studying or practicing in New York hospitals. So Chinn formed a private practice and made house calls, sometimes operating in patients’ living rooms, using an ironing board as a makeshift operating table.
Chinn worked among the city’s poor, and in doing this, started to notice her patients had late-stage cancers that often had gone undetected or untreated for years. To learn more about cancer and its prevention, Chinn begged information off white doctors who were willing to share with her, and even accompanied her patients to other clinic appointments in the city, claiming to be the family physician. Chinn took this information and integrated it into her own practice, creating guidelines for early cancer detection that were revolutionary at the time—for instance, checking patient health histories, checking family histories, performing routine pap smears, and screening patients for cancer even before they showed symptoms. For years, Chinn was the only black female doctor working in Harlem, and she continued to work closely with the poor and advocate for early cancer screenings until she retired at age 81.
Alice Ball

Alice Ball was a chemist best known for her groundbreaking work on the development of the “Ball Method,” the first successful treatment for those suffering from leprosy during the early 20th century.
In 1916, while she was an undergraduate student at the University of Hawaii, Ball studied the effects of Chaulmoogra oil in treating leprosy. This oil was a well-established therapy in Asian countries, but it had such a foul taste and led to such unpleasant side effects that many patients refused to take it.
So Ball developed a method to isolate and extract the active compounds from Chaulmoogra oil to create an injectable medicine. This marked a significant breakthrough in leprosy treatment and became the standard of care for several decades afterward.
Unfortunately, Ball died before she could publish her results, and credit for this discovery was given to another scientist. One of her colleagues, however, was able to properly credit her in a publication in 1922.
Henrietta Lacks

The person who arguably contributed the most to scientific research in the last century, surprisingly, wasn’t even a scientist. Henrietta Lacks was a tobacco farmer and mother of five children who lived in Maryland during the 1940s. In 1951, Lacks visited Johns Hopkins Hospital where doctors found a cancerous tumor on her cervix. Before treating the tumor, the doctor who examined Lacks clipped two small samples of tissue from Lacks’ cervix without her knowledge or consent—something unthinkable today thanks to informed consent practices, but commonplace back then.
As Lacks underwent treatment for her cancer, her tissue samples made their way to the desk of George Otto Gey, a cancer researcher at Johns Hopkins. He noticed that unlike the other cell cultures that came into his lab, Lacks’ cells grew and multiplied instead of dying out. Lacks’ cells were “immortal,” meaning that because of a genetic defect, they were able to reproduce indefinitely as long as certain conditions were kept stable inside the lab.
Gey started shipping Lacks’ cells to other researchers across the globe, and scientists were thrilled to have an unlimited amount of sturdy human cells with which to experiment. Long after Lacks died of cervical cancer in 1951, her cells continued to multiply and scientists continued to use them to develop cancer treatments, to learn more about HIV/AIDS, to pioneer fertility treatments like in vitro fertilization, and to develop the polio vaccine. To this day, Lacks’ cells have saved an estimated 10 million lives, and her family is beginning to get the compensation and recognition that Henrietta deserved.
Dr. Gladys West
Andre West
Gladys West was a mathematician who helped invent something nearly everyone uses today. West started her career in the 1950s at the Naval Surface Warfare Center Dahlgren Division in Virginia, and took data from satellites to create a mathematical model of the Earth’s shape and gravitational field. This important work would lay the groundwork for the technology that would later become the Global Positioning System, or GPS. West’s work was not widely recognized until she was honored by the US Air Force in 2018.
Dr. Kizzmekia "Kizzy" Corbett
TIME Magazine
At just 35 years old, immunologist Kizzmekia “Kizzy” Corbett has already made history. A viral immunologist by training, Corbett studied coronaviruses at the National Institutes of Health (NIH) and researched possible vaccines for coronaviruses such as SARS (Severe Acute Respiratory Syndrome) and MERS (Middle East Respiratory Syndrome).
At the start of the COVID pandemic, Corbett and her team at the NIH partnered with pharmaceutical giant Moderna to develop an mRNA-based vaccine against the virus. Corbett’s previous work with mRNA and coronaviruses was vital in developing the vaccine, which became one of the first to be authorized for emergency use in the United States. The vaccine, along with others, is responsible for saving an estimated 14 million lives.On today’s episode of Making Sense of Science, I’m honored to be joined by Dr. Paul Song, a physician, oncologist, progressive activist and biotech chief medical officer. Through his company, NKGen Biotech, Dr. Song is leveraging the power of patients’ own immune systems by supercharging the body’s natural killer cells to make new treatments for Alzheimer’s and cancer.
Whereas other treatments for Alzheimer’s focus directly on reducing the build-up of proteins in the brain such as amyloid and tau in patients will mild cognitive impairment, NKGen is seeking to help patients that much of the rest of the medical community has written off as hopeless cases, those with late stage Alzheimer’s. And in small studies, NKGen has shown remarkable results, even improvement in the symptoms of people with these very progressed forms of Alzheimer’s, above and beyond slowing down the disease.
In the realm of cancer, Dr. Song is similarly setting his sights on another group of patients for whom treatment options are few and far between: people with solid tumors. Whereas some gradual progress has been made in treating blood cancers such as certain leukemias in past few decades, solid tumors have been even more of a challenge. But Dr. Song’s approach of using natural killer cells to treat solid tumors is promising. You may have heard of CAR-T, which uses genetic engineering to introduce cells into the body that have a particular function to help treat a disease. NKGen focuses on other means to enhance the 40 plus receptors of natural killer cells, making them more receptive and sensitive to picking out cancer cells.
Paul Y. Song, MD is currently CEO and Vice Chairman of NKGen Biotech. Dr. Song’s last clinical role was Asst. Professor at the Samuel Oschin Cancer Center at Cedars Sinai Medical Center.
Dr. Song served as the very first visiting fellow on healthcare policy in the California Department of Insurance in 2013. He is currently on the advisory board of the Pritzker School of Molecular Engineering at the University of Chicago and a board member of Mercy Corps, The Center for Health and Democracy, and Gideon’s Promise.
Dr. Song graduated with honors from the University of Chicago and received his MD from George Washington University. He completed his residency in radiation oncology at the University of Chicago where he served as Chief Resident and did a brachytherapy fellowship at the Institute Gustave Roussy in Villejuif, France. He was also awarded an ASTRO research fellowship in 1995 for his research in radiation inducible gene therapy.
With Dr. Song’s leadership, NKGen Biotech’s work on natural killer cells represents cutting-edge science leading to key findings and important pieces of the puzzle for treating two of humanity’s most intractable diseases.
