I will explain in the next Xeet.

@i_petersen @disnenchanted @Embyeye @GeorgeMonbiot It would be interesting to see what ChatGPT4 would have to say about. (I know GPT4 sometimes makes stuff up. But this seems pretty damn good!)

Q. Is there evidence that HEPA filtration in a room can reduce viral load and level of infection?
1/n @i_petersen @disnenchanted @Embyeye @GeorgeMonbiot 2/n ChatGPT
Yes, there is evidence suggesting that high-efficiency particulate air (HEPA) filtration can reduce the concentration of airborne viral particles in a room, potentially reducing the risk of transmission of respiratory viruses like #SARS_CoV_2, which causes COVID-19.

It occurred to me yesterday (1 of maybe many reasons) why I have pulmonary fibrosis. I spent the spring of 2007 helping Dave Hansen restore this British Firefly. Dave passed away a few years ago of cancer. We used the meanest, strongest, paint stripper known to man; CH₂Cl₂ 1/n 2/n

Today we talk a lot about ventilation because of the pandemic, yes, outdoor air is about as safe as you can get when talking about ventilation, I did a lot of the paint stripping outdoors, and didn't bother to where a respirator. Dave Hansen had a high tech paint booth,

@organichemusic Enovid I believe works.... not 100%, but has kept a bronchial infection at bay that my niece brought to our home last week from Mesa, AZ. Enovid seems to have some side effects, day 5 blurred vision that lasted most of the day, but went away. Otherwise seems safe. 1/n @organichemusic 2/n When I went to the airport to pick up my brother & his daughter, my Vflex N95 was not in the center consol. My wife cleaned out the car. 🤦‍♂️Not knowing they might have any kind of illness at all, I wanted to wear the Vflex to be safe. I kept windows cracked and vent open.

I was the hostage in this incident. I was on my laptop looking up the latest trends for influnza on the @CDCgov site. The waiting room was crowded/coughing & I was the only one wearing a mask, ASTM Level III.

deseret.com/2005/1/26/1987… 2/ They I remember thinking when I first walked in to the waiting room, "This is not where I want to be right now" almost every seat was taken, and most everyone was coughing. A sign read, it is the flu season, if you want a mask, ask for one. No one was wearing one...

Pricing left to right: $125, $249, $85, $60.
The first 3 are NDIR, the 4th is eCO2. I’ll post a bit later today comparison of ARANET4 with Sensirion SCD30 (not shown) but, both comparable to each other showing much higher CO2 ppm than the other 3 cheaper sensors. @kprather88 Both the $125 & $85 model use the exact same CO2 sensor, CUBE CU-1106 single beam NDIR.

Why couldn’t he and other medical professionals make the connection until now?
