While fresh air is good, trying to clean the air chemically is not. The atmospheric chemistry community has been saying this for a long time; the best ways of cleaning indoor air is physical removal (filters/sorbents/air exchange).
New air cleaner paper! @airqing.bsky.social challenged an oxidation-based cleaner with an air freshener, and saw tons of chemistry. In particular, ethanol (a common ingredient in cleaning products, and ubiquitous indoors) oxidized to form acetaldehyde and formaldehyde.

Paris shows what happens when cities put people before cars: cleaner air, greener streets, and healthier lives. The data (and the air) speak for themselves! 🌱🚶♀️🚴
“Air pollution fell substantially as Paris restricted car traffic and made way for parks, people-streets and bike-lanes.”
Better for the climate, better for health, better for livability and quality of life.
Common sense.
Such a no-brainer, it’s remarkable that more cities HAVEN’T done the same.

Just to reinforce it - my entire house caught covid this past summer because after four years and change of scrupulously masking I was briefly exposed to the movers, likely from being in the same poorly ventilated room too soon after they had been.
