It's always hard to start in a new place. Especially one where the algorithm isn't trying to feed us a constant barrage of hate, crap, or bots.
Then again, it means on Bluesky we have to redouble our support of other worthwhile accounts so they continue to grow sharing good info (vs disinfo on X).

An air filter canโ€™t clean the air if it isnโ€™t turned on.
A mask doesnโ€™t work if it isnโ€™t worn properly.
And a pandemic isnโ€™t ended by pretending it isnโ€™t happening.

Yes, air filters donโ€™t work if you donโ€™t turn them on. And of course masks donโ€™t work if you donโ€™t wear them properly or constantly take them off. Same as how your brain doesnโ€™t work if you choose to not use it.

Will the Last Expert to Leave ACIP Please Turn Off the Lights If you've got expertise, better get the hell out of voluntarily advising the US government

The all-villain ACIP continues to hemorrhage actual expertise. It's pretty hard to take out the MMR and polio vaccines if there are annoying experts around to inconveniently talk about their benefits and safety record.

Badly designed studies give the wrong answers.
Here, air filters were used in *some* residents rooms; always on sleep mode.
In communal areas they were also hugely underpowered.
The level of air filtration is super-important.
Seemingly not to researchers designing studies.
1/๐Ÿงต 
2/ I'd expect honest reviewers to see the issues here immediately rather than report 'doesn't work'.
It's as simple as me studying whether heat can cook chicken.
I raised the chicken temp by 1 degree C.
Chicken remained raw.
Therefore heat does not work to cook chicken โŒ.
2/ 
It's absolutely as obvious as that.
We'd then compare the untreated chicken and that where temperature was raised by 1 degree and find no significant difference.
Would anyone be at all surprised?
It's the same with air filtration; the amount matters. Like it really matters.
3/ 
When this study was being promoted prior to it starting back in October 2021, it was blindingly obvious to me then that it was flawed from the outset. I questioned it.
If it's obvious to me, why on earth was it not obvious to those undertaking the work?
4/

Well that's because there is a significant skills gap.
They probably never even asked an engineer or someone incredibly familiar with air filtration.
Just bought some devices, plugged them in with about 1 ACH max. Probably never even checked again if they were even turned on.
5/ 
I just find it so incredibly pathetic.
Those opposed to clean air will revel in this but they just seem more and more disingenuous every time they comment on something like this.
They cannot command any respect from those that know - but the headlines are what get remembered.
6/ 
Fiona should hang her head in shame.
No doubt the gatekeepers elsewhere will also latch onto this but make no mention of its shortcomings.
I see councils making the same mistakes, buying really inappropriate machines for schools.
Ineptitude; destined to fail from the outset.
7/ 
So anyway, studies like this tell us absolutely nothing about whโ€ฆ
