Yup. 100% I never enter any public indoor space without a high quality mask.

I recommend reading the article by @billmckibben.bsky.social that notes 71.5% of adults reported fatigue. www.nytimes.com/2026/09/29/o... Good stuff. Just want to add one layer to the mix: "Study: COVID-19 Associated With Quadrupled Risk of Chronic Fatigue" www.usnews.com/news/health-...

It's hard to watch so many people in Pennsylvania alarmed by the state's measles outbreak but still not wearing masks. In hospitals, schools, or really anywhere for that matter. COVID never left and now measles is on the rise. N95 or better masks could make a world of difference.

I went to see a #ProjectHailMary yesterday on opening day! Rented a theater space, invited some masked friends, checked the CO2 with my Aranet4 (it ranged from about 550-650ppm), and even ran a bunch of AirFanta 3Pro air filters! @aranethome.bsky.social #AranetDiscovery

Heads-up: #COVID levels in Pittsburgh wastewater are "Very high" right now. See for yourself at www.pa.gov/agencies/hea... . #WearAMask #airquality

Correction!! Turns out that the recent super-high wastewater readings were errors. I got suspicious and so asked the PaWSS team about it directly, and they fixed it! So fortunately COVID wastewater levels are currently "Moderate." Not great but better than 3x high.

😷Mark Dixon @markdixon.bsky.social · 24/11/2025
Quick heads-up this Thanksgiving in Pittsburgh: recent COVID wastewater levels are higher than they have been since April 2023. You can decrease your chance of catching/giving COVID by testing before gathering, opening windows, filtering the air, wearing masks, and more!

My wife, @mchristinebd.bsky.social, did a book event yesterday and I tagged along to watch and also set up 6 AirFanta 3Pro air filters to reduce viral transmission. (Five pictured, one more in back. Plug spots limited options.) We both wore high quality masks, too. #COVIDisnotover #AirQuality

A free and democratic society cannot silence comedians because the President doesn’t like what they say. This is an attack on free speech and cannot be allowed to stand. All elected officials need to speak up and push back on this undemocratic act.

PSA Neck gaiters are not masks. Neck gaiters are not effective at stopping the spread of airborne viruses. Masks, especially well-fitting ones are effective at preventing infection. Conflating the two is bad because it can encourage politicians to ban masks for the general public.
