Within airconditioned vehicles, the CO2 levels rise up to 10000 ppm (normal is 420 ppm), causing drowsiness and inattentiveness to people within. Ventilation (opening the window) can reduce the CO2 levels within minutes.02 Jun 2025 14:53 +0000at://did:plc:zeddec6iroea4vhsqbf2vkcq/app.bsky.feed.post/3lqmzr5j6qc2ghttps://bsky.app/profile/joshuacagar.bsky.social/post/3lqkncbn6hs23Those campaigning against bicycle lanes insist that bike commuting is unsustainable due to air pollution. A KN95 mask w/ valves (to address the moisture building & pressure resistance) will do the trick against pollution. It works inwardly against respiratory diseases too.01 Jun 2025 16:05 +0000at://did:plc:zeddec6iroea4vhsqbf2vkcq/app.bsky.feed.post/3lqkncbn6hs23https://bsky.app/profile/joshuacagar.bsky.social/post/3ldzt3n6nek2jMy wife and I wish you all safe travels and a Merry Christmas.
