Is there a MERV rating at which an electret filter would generally not degrade below MERV-13A over a long service life? MERV-15? 16? Too much variation? @BrettCSinger1 @CorsIAQ @DavidElfstrom @IAQinGWN @JimRosenthal4 @jljcolorado @linseymarr @marwa_zaatari @Poppendieck

If you have been trying your best to ignore COVID-19, along with the steady scientific discovery of its pathology, you may want to take a moment to re-evaluate the potential consequences.

This isn’t NYC today. This was 1973, just after the EPA was created and before it transformed air and water quality. In those early years the agency enlisted photographers to catalogue environmental disasters before they were cleaned up. The climate crisis is reversing history.

🚨 Novavax Action 🚨 The FDA is meeting soon for fall variant selection. Public comments are open until TOMORROW. We are taking this opportunity to demand broader access to Novavax COVID-19 vaccines, especially for children. Why do we need more access to Novavax? Thread 🧵

If you haven’t been paying attention or reading medical journals lately, take a moment to read a great thread from someone who has.

The reason you aren't seeing many masks in conference and holiday party photos is because the people smart enough, responsible enough, and/or vulnerable enough to wear them can't or won't attend inequitable, unsafe events.

It has become quite apparent that we have become a society where intellectual curiosity is to not be celebrated and individual thought is to be replaced with group think, where everyone is dumbed down to the detriment of many.

It is no accident or coincidence that the general public in many countries came to believe the lie that it's fine to catch and spread Covid.

Sunday story time ❤️ 1/ Once upon a time, in a land far away, a bunch of oligarchs didn’t want to pay taxes, feeling angry because they couldn’t gorge themselves on other people’s fruits of labour the way they felt they deserved to.

This is from The Tonight Show with Johnny Carson aired on May 20th, 1977. Carl Sagan says something very important, a strong message that didn't lose any validity since then. [full interview: buff.ly/3h2ufYP]

This is an excellent summary of what is currently known to happen in the body from a SARS-CoV-2 infection, even if it is asymptomatic or “mild.” This is the kind of information that would be necessary for informed consent if governments were interested in that kind of thing.
