This chart shows the precipitable water column globally. That translates to the amount of water being held in the atmosphere. Right now we are at the highest level ever recorded. That means, when combined with the incoming super el Nino, the resulting storms will be catastrophic. You are warned.

Sometimes you find the current situation articulated perfectly: x.com/brownecfm/st...

Got this email from "Ralph, BC" describing a great way to automate operation of our Polaris Ultra air purifier: Very satisfying to see how other people are making use of them for more than Covid risk mitigation.

~ 500,000 journal articles later, there’s about a half a million reasons to adapt to living with COVID by implementing logical and evidence-based protections against this novel virus, and there… 1/4

This is actually quite brilliant, up to and including the final sentence 🔥

It's not amnesia. It's reality avoidance and, in many cases, willful ignorance

Our MINI-SC is entirely built by hand and takes quite a while to make but it's just so much fun to put together! #airpurifier #indoorairquality #covidisairborne

Checking out some nifty digital timers to add automation control to an air purifier. Up to 15Amps so you can have multiple units controlled. Great for classrooms where you can just hit the 8-hour button and you are good! #indoorairquality #covidisnotover

There’s a historic indoor clean air high level event at the UN today. @drbronking.bsky.social is of course leading by example wearing a high quality mask while chairing the meeting 👏👏👏

Whole bunch of different stuff on the bench today, including some prototypes we are working on! #IndoorAirQuality #COVIDisAirborne #airpurifier

Realizing the original 8 x 80mm fan was misguided, here is the redesigned Guardian. My goal was to make the cheapest, quietest and most portable solution. Aiming for chemo patients going into hospital, it can be a great solution for any smaller space. 1/2

We've just posted the updated kit assembly video for our North Box MINI-SC portable air purifier, now with electronic speed control! youtu.be/FvwPNqbxTV8?...

“More than five years after the coronavirus stormed into our lives, scientists are still piecing together why it was so deadly — and why it’s left millions with lingering illness.” Notice the verb tense? It should be “why it *is* so deadly” and “leaves” not “left.” www.bloomberg.com/news/newslet...

It's #CleanAirDay today! 💨 This day is to recognize how important good air quality is, and to be aware of the many adverse effects pollution and wildfire smoke can have on our environment and our health. 🫁 #CleanAirEverywhere #CleanAir #Pollution #WildfireSmoke

On #CleanAirDay, it's crucial to share how important it is to also think about air quality indoors. Using a HEPA air purifier, North Box PC-fan air purifier, or CR box can help! 🏠💨 #CleanAir #AirQuality

Though our air purifiers can help keep your indoor air safe during wildfire season, filters should be changed after a major smoke event as their electrostatic properties can be compromised. #wildfiresmoke #wildfires #cleantheair #COVIDisAirborne

But govt of Ontario DID upgrade the building they work in every day 🤔 #ONpoli “This government invested over $1B to update the ventilation in Queen’s Park, almost twice as much as the investment made in all of our schools province-wide. Why would they do that if they didn’t think it was important?”

Really happy how this modification to the MINI turned out. Built-in speed control just makes this thing so much more practical!

Covid is not “mild”. It’s not just a cold. infections don’t make you stronger & can cause significant harm Grateful to anyone with a platform who speaks out about their struggles. People need to understand repeat infections aren’t inevitable. Masking & clean air works. We just have to do it

Thx, @geoffypjohnston.bsky.social - one of the great journalists out there unafraid to speak about topics some would rather avoid. ICYMI: @onschoolsafety.bsky.social’s letter consisting of the recommendations to which Geoff refers in his interview: www.ontarioschoolsafety.com/updates/open...

Andry José Hernández Romero, I remember you, even if I do not know how to articulate my horror, rage, & sorrow at your treatment by my government. No one has heard from you in 43 days. As vigil, I’m posting a photo of you every day until you are returned from El Salvador.

Almost 10% of the entire Canadian electorate voted on the VERY FIRST DAY of advance polls because we’ve spent the last 3 months watching what happens when you elect a populist windbag who vilifies journalists and shits all over people’s fundamental rights. Thanks America. You really did us a solid.

I had to fly a few times and I always use my PrescientX Breathe for those long hauls. Highly recommended!

More confirmation that air purifiers are effective at removing airborne virus particles. A PC-fan based air purifier will give you excellent performance without the noise of a HEPA cleaner: www.sciencedirect.com/science/arti...

CR Boxes & UFP (a thread) Starting another study of CR Boxes, this time for removal of ultrafine particles (UFP). Doing some prelim experiments on ability of an aged CR Box (below left) to remove UFP from indoor air as prep for new study. Soiling shown at right relative to unused filter.

Exactly right, @flannerydean.bsky.social. Thank you for writing about this. And, thank you @canadahealthwatch.bsky.social (twice in one night!) for carrying the piece! @onschoolsafety.bsky.social @onthealthcoalition.bsky.social

A little tape can do a lot to spice up your air purifier. I call this FACT001 Hacienda Edition in honour of the legendary Manchester club where New Order and The Birthday Party performed in the early 80's. #IndoorAirQuality #NewOrder #FactoryRecords
