I love having a CO2 monitor to check the air quality in indoor spaces (my grocery store, my dentist’s office, etc.). I’m relieved when stores have good ratings, and I’ve convinced my dentist’s office to open windows to get the rating down to an acceptable level.

I use an #Aranet4 and thanks to @brainwane I learned they are on sale (at quite a discount) until Sept. 17. Highly recommended for the Covid-cautious who don’t have one already.

#Covid #Cvoid19 #CovidIsNotover

China revised the #COVID19 death toll in Wuhan from 2,579 to 3,869. I’m revising my estimate from 5-6,000 to 14-15,000.
Warning: Indian states are actually worse than China in under-reporting the #CVOID19 numbers.
