#AltText: photo of a boxy chandelier, faced with fans that are glowing cyan and teal, with splashes of neon-hued magenta, purple, blue, green and yellow. The fans have subtle diagonal braces and hexagonal enclosures which enhance the pronounced vapourwave aesthetic, which could be from 1987 or 2027.
On closer inspection, it can be recognized as a fancy Corsi-Rosenthal Box.
The future is now!

@thetyee I see that C-R box in the background!
Good to know that the Tyee office is following the science, as you've sometimes reported on.
Best wishes that you each stay physically and cognitively healthy, and that your ongoing efforts for excellent reporting are never impeded by long covid.

at first I changed the filters after 6 months. But after reading some of Dr. Corsi's tweets I decided to go for every 12 months. So I had last changed the filters September 2023. Look at the difference! I did take them and shake out the worst of the dust outside in the Spring.
