In Jan there was a conference:
Breathing achievement into every classroom
This conference was designed to probe the link between Indoor Air Quality (IAQ) in educational buildings and the health, wellbeing, and educational outcomes of students.
UKHSA presented & IAQ experts.
1/🧵
This was something of a surprise to me.
I'm faced with a presentation from @UKHSA and some of their Key Recommendations are:
• Use of air cleaners in naturally ventilated buildings.
• Ensuring provision of adequate classroom ventilation
This seems like quite a breakthrough.
2/
~90% of UK schools are naturally ventilated.
This recommendation is that air filters are put into all naturally ventilated classrooms.
I've been calling for this for a number of years now and I never thought I'd hear @UKHSA recommend this given the years of pushback from Gov. 3/
But the presentation went far further than this.
It is clear that they know the link between IAQ and absenteeism.
They also recommend that cost/benefit analysis looks at the wider picture.
They know there are significant cost savings & health benefits. 4/
They know that better indoor air improves student performance: 5/
They know that higher ventilation rates are needed to cope with infectious airborne diseases like Covid and of course, this is the missing link from the presentation; it's mainly about pollutants, not disease and all past tense but I still take this as a major step forward. 6/
More on absence: They know that poor indoor air quality & environment leads to increased absenteeism.
They haven't quite made the link to infectious diseases & absenteeism which is obviously an even more significant aspect for absence through illness.
Nonetheless; still good: 7/
There are a lot more points to make but I just wanted to jot this out quickly to acknowledge the work of the people below from UKHSA (who are not on here) and share the hope that change is coming.
Thanks @mishwoz or @CleanAirClassrm for signposting me to this conference. 8/
Here is a link. Scroll down and the full presentation from all speakers, including Prof Cath Noakes and @HenryBurridge is available to download from this link.
Now we need to ensure it gets implemented & the right air filters are used. 9/ eurovent.eu/events/iaqmatt…
By 'the right air filters' I mean schools getting proper advice from folk who truly know.
Key:
High CADR performance with low noise. No added tech inc UV inside or ionisers. Low cost, low power usage, easy maintenance, accessible replacement filters, no auto function etc.
10/
I say this because I saw a UK Council lauding their achievements for what they're using and honestly, the machines installed tick almost none of the items on my list of key requirements ❌
Ending up with the wrong thing and spending a fortune doing so disappoints me greatly.
11/
When things come up for tender (as with the Council), please make sure the list of requirements is made by someone who knows this stuff; rather than someone who thinks they do or is just buying from a preferred supplier or based on some study or other.
Get the right advice.
12/
Lastly UKHSA are making these recommendations, true but who to:
Well I am assuming to policy makers to Department for Education and Government more broadly.
And if they know this is needed in schools, they must also know it's needed in all indoor settings.
Stay hopeful.

Electrostatic filtration media used to make respirators and air filters is a true marvel of science & engineering.
Odd that some think it doesn't work.
HEPA filters have been around for decades too.
HEPA filter technology actually makes it possible for you to read this post.
1/🧵
"Producing the semiconductor chip that you have in
your computer, phone or tablet, is a highly sensitive process. The chip has to be fabricated
in clean rooms where HEPA filters ensure the air contains less than 1 particle per cubic foot." 2/ camfil.com/en/insights/li…
"As a comparison, most common indoor spaces have hundreds of thousands of air particles per
cubic foot."
Pretty useful tool eh?
Let's also have a look back to 1980 when a paper was written about electret filters. The type of media used in respirators: 3/ sciencedirect.com/science/articl…
Saddened to hear football legend Ian Rush spent 2 days in ICU and is still in hospital with flu.
It can happen to anyone at short notice.
What people don't realise is that when it does, very little is done in hospitals to prevent co-infections with other airborne pathogens.
1/🧵
When so poorly, you are extremely vulnerable.
You really need to be kept away from other airborne diseases (and other germs of course).
But in my experience, the air quality inside hospitals can be very poor. Nothing like good enough to prevent spread of covid for example. 2/
Also, staff & visitors in many UK hospitals are not required to wear any respiratory protection.
Worse still, staff are encouraged to be at work even if covid +ve as long as 'they feel well'.
The staff are not even protected from the patient and could get a co-infection too.
3/
During the Cvd inquiry, I noted so many references to decisions having to be 'evidence based'.
I would like these people to produce one single piece of evidence that this advised technique prevents transmission of diseases - airborne and other modes.
👀Show me the evidence.
1/🧵
For example, how many times have we been thwarted when wanting to put air filters into classrooms?
Even as a simple emergency measure early on we were told that not enough evidence of efficacy exists.
So much so, that RCTs were called for and then never published.
2/
Ever wonder how much of their advice is actually based on evidence?
Like; is 'consider wearing a mask' based on evidence? Does someone considering doing so ever stop a single infection? Of course not.
Does evidence exist that washing hands prevents cvd infections? Nope.
3/
Ppl say 'I've had a bout of Covid'.
In a real bout, like boxing, fighters prepare well. Honing skills to try to defend themselves.
Most ppl do nothing to avoid Covid.
Boxing is typically 12 rounds and not infinite rounds like Covid, as each new wave swerves their defences.
1/🧵
But what people really don't get is that you sustain damage with each round.
You might not even perceive it or it might knock you down.
The damage may manifest later with people not even connecting the 'bout' they had to their worsening health or decreased cognitive ability.
2/
You see this in boxing too. Fighters can sustain damage in a fight and continue through to the end but then collapse after the fight is over or suffer brain damage years later from taking hits over a sustained career.
When boxers suffer in this way, people are never surprised.
3/
The fact that proper messaging about the harms of covid infection, long covid & effective ways to protect yourself has been left to members of the public to advocate for is a massive frustration to me.
People are generally unaware because of a total Public Health failure.
1/🧵
It isn't just a failure to provide the correct information; it's worse than that. It's a concerted effort to provide inaccurate info which is fed to the public through the media; the BBC for one who are entirely complicit in causing harm. Today's article is a prime example.
2/
I spoke to a contact I hadn't been in touch with for a while. It was clear that she was concerned about Covid and other infections for herself and her teenage kids. She told me one teen wears a neck gaitor over his mouth & nose and uses hand gel when travelling by train.
3/
An anecdote from me as a small business owner.
I see many more mistakes & mix ups from my clients than I've ever known.
Obvs I get more 'out of office ill' replies too but Covid affects the brain & it's noticeable imho.
Mistakes are increasing; sometimes financial ones.
1/🧵
Today for example, I had a company pay an invoice that was due to an entirely different company with that starts with the same letter. Refund issued.
Also today, another customer paid an invoice that they had already paid. Another refund issued.
2/
The burden of errors costs businesses. Not every company will be upfront about receiving mispayments but it's also taking our time up trying to reconcile accounts, having to deduce the issue, get bank details for customers and then go through the process of sending £s back.
