Mayor of London, Sadiq Khan @london.gov.uk · Jun 23

The fight to limit global warming is the defining challenge of our time.

Success will be measured not only in degrees, but in homes spared and lives saved.

In Paris, I spoke about how cities have proven themselves to be the climate doers while national governments have dithered.

Here’s a school seeking to improve attendance from within, by cleaning the air for staff and students.

Please help them by donating (even if it’s a small amount, it all helps) and by sharing.

Thank you.

As in the 19th century, does your child's school have:
- high ceilings to increase room volume?
- high windows for continuous ventilation?
- large windows for better ventilation?
- Opposite openings for air circulation?
- All windows open outwards to improve ventilation?

A new study shows that air cleaners can reduce up to 98,1 % of viral load in the air of a #COVID patient's room with confirmed positive airborne viral RNA.
Rooms with HEPA ventilation had zero virus detected.

A study of masks and respirators confirms, yet again, that earloop KN95/KF94 masks perform similarly to surgical masks. Earloop masks should not be recommended as a substitute for proper headstrap N95 respirators—except for the rare wearer who passes a fit test in them.

Importance Masks reduce transmission of SARS-CoV2 and other respiratory pathogens. Comparative studies of the fitted filtration efficiency of different types of masks are scarce. Objective To descri...

Just to reinforce it - my entire house caught covid this past summer because after four years and change of scrupulously masking I was briefly exposed to the movers, likely from being in the same poorly ventilated room too soon after they had been.

Graphic of a person sneezing. Text reads:

YOU CAN GET COVID IN AN EMPTY ROOM
"The most common way COVID-19 is transmitted from one person to another is through tiny airborne particles of the virus hanging in indoor air for minutes or hours after an infected person has been there."
Dr. Alondra Nelson, head of the White House Office of Science and Technology Policy and Deputy Assistant to the President
COVID IS AIRBORNE
The virus hangs in the air and gets inhaled.
PROTECT YOURSELF
Bring clean air into the room you are in and clean the air already in the room.
CLEAR THE AIR
Ventilation, Air filtration, UVGI can remove virus particles from the air and keep you safer.

Global experts reach consensus on Long COVID caused by airborne SARS2 virus

🔹LC = organ damage, immune
dysfunction, neurological injury
🔹Kids are affected
🔹Clean indoor air is vital
🔹Most standard tests miss it
🔹Invest in diagnostics & treatment

Indoor Air Is a Prevention Strategy
Long COVID is, to an extent, preventable. Reducing airborne transmission of the virus through improved ventilation and air purification-particularly in schools and workplaces-is essential public health infrastructure”

Babysitting grandcats makes my asthma act up so, we keep the HEPA on 24/7.

When Mae West was doing her sphinx imitation, I saw she needed a good brushing.

I wore a N95 while brushing - she purred and I could breathe.

10/10 recommend.

I fully agree with Prof. Chris Whitty and Dr. Hans Kluge of the WHO.

The great lesson of the pandemic has been the importance of Indoor Air Quality.

Improved IAQ would also reduce RSV, flu etc, and prepare us for the next pandemic.

Ireland had the 4th highest rate of asthma in the world in 2019.

How do 3rd party filter compare to originals? Here's some data on air velocity with Rioche & Pureburg replacements (also without carbon filters) for the Mistralaire MAP350G. Interestingly HEPA thickness was less in the Rioche due to a thicker carbon filter...
