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.

Conversation with relative I haven't spoken to in a while. I'm a bit of an outcast because of my strong views on Covid but with my mum being unwell, family are contacting me for updates.
It's such an enigma to me how people's brains work (or don't).
Here's how it went:
1/🧵
Me: I think things started to go downhill for mum when she got shingles.
Rel: Yes I agree. She declined quickly after that.
Me: And people thought it was safe to ignore chicken pox and decades later, it started her demise.
Rel: Yes it lies dormant and can be very serious.
2/
Me: This is why I take Covid seriously. There's a lot we don't know but what we do know from studies urges more caution.
Rel: Well you just have to carry on as normal. When it started, my son worked every day as a key worker. You can't just stop everything indefinitely.
3/
My mum still in hospital. I have reported on the terrible air quality and lack of respiratory protection but I was unprepared for what happened on tonight's visit.
For the 40th time, I visit the ward she's on. As I walk in, nurse says "you know your mum isn't here, right?"
1/🧵
Well of course I did not know this.
"They moved her in the night"
Where to?
"I'm not too sure - ask at the nursing station"
Why did they move her?
"I don't know"
Another nurse arrives "They moved her to W9"
Why?
"I don't know - ask W9"
Why did nobody inform me?
"I don't know"
2/
As her next of kin, I can't understand not being told this.
Anyway. I arrive in W9.
I'm looking for (mum's name).
"Are you sure she is on this ward"
As it happens, not really but I've been told she was moved here.
"Not on my section. Ask the nurse on Bay A"
3/
Those who say they've 'moved on' from Covid have nothing more than denial & hope.
Us apparent 'zealots' actually look at data and studies. We understand that we're a short way into a long term issue; the full effects of which will take years to be fully obvious & undeniable.
1/🧵
Finding out several years down the track that what us 'weirdos' have been saying for years was right will be much too late for many.
We also know that if things turn out better than we expect, all we did was adapt our lives to reduce our odds of being irreversibly affected.
2/
We also know many people who have already been really seriously affected by covid infections. We don't ignore them or gaslight them. We listen and acknowledge that what they are suffering is very much inline with what studies have shown covid does to harm us.

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.
