Merry Christmas 🎄 🥂 Most winter bugs don’t mainly spread via touch. Flu, RSV, COVID, colds and more spread through shared indoor air - even without coughing. Normal breathing and talking is enough. Open the windows, even just a bit. Freshen the air. #IndoorAirQuality #CleanAirWhere

Study in Helsinki indicating benefits of portable air cleaners on lowering infection risk in daycare centers, less absences & parent absences from work in intervention vs. reference (no air cleaner) groups. Cleaning indoor air is not difficult and it works. www.sciencedirect.com/science/arti...

🧵1/ Flu is surging again, & patterns look uncomfortably familiar. The lesson from covid remains unchanged: individual responsibility isn’t enough. We need systemic measures that make protective behaviours easy. @profstevegriffin.bsky.social Stephen Reicher & I offer some thoughts @bmj.com

For anyone new here - I’m Hannah, an NHS radiographer and a mum In 2020, I went down a clean air information wormhole and it completely changed how I see everyday life - our health, energy, and how we function day to day Clean Air Where grew from that shift in perspective #CleanAir #AirQuality

We're half a decade into studies finding that improving airflow in classrooms will reduce disease transmission enormously, and that bleaching surfaces etc. does very little. And yet nothing changes. Waves of flu and colds wash over schools, and the schools pretend it's an act of God.

A small update as the Clean Air Where map starts to grow, one pin at a time. 10 London spots added, all with outdoor space and added for free to help people find safer places this season. It’s early days but every pin helps someone choose somewhere they can actually go…

Myth: Cold weather makes you sick Reality: Shared indoor air does ❄️ Cold ≠ illness 🦠 Viruses spread fastest in indoor, poorly ventilated spaces 🌬️ Outside is one of the safest places to be • Wrap up warm • Don’t fear the cold • Prioritise ventilation + filtration Clean air prevents illness -not coats

While fresh air is good, trying to clean the air chemically is not. The atmospheric chemistry community has been saying this for a long time; the best ways of cleaning indoor air is physical removal (filters/sorbents/air exchange).

Great news as Prof Lidia Morawska who has done fantastic work on particulate matter and raised awareness of the fact that covid 19 can be spread via airborne route has just won a prize in recognition of her achievements

On #WorldVentil8Day we are reminding everyone: 💨 Clean indoor air saves lives! 💨 Flu risks are high this year and ventilation, filtration, high-grade masks, and CO₂ levels still matter. We are proud to be a founding supporter of #WorldVentil8Day

🌬️ Today is #WorldVentil8Day We’ve released Clean Air Where into the wild — a live map showing indoor air quality and venues with outside space. See the air before you’re there. We’re looking for venues to join the map 👇 cleanairwhere.com

As #WorldVentil8Day 2025 is only 3 days away here’s a little reminder of some ventilation tips I gave last year 👇

Paris shows what happens when cities put people before cars: cleaner air, greener streets, and healthier lives. The data (and the air) speak for themselves! 🌱🚶‍♀️🚴

I want every single child to breathe clean air in and around their school. This new £2.7 million City Hall initiative will provide indoor air quality filters to at least 200 schools across all London boroughs, benefitting tens of thousands of children.

Motherfucking wind farms…

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. www.crowdfunder.co.uk/p/qr/Zn564vb...

Today is Clean Air Day. View the recording of our joint union webinar on improving air quality in schools to find out more about the effects of ventilation as well as practical solutions to put in place to clean the air we breathe. youtube.com/playlist?lis...

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. 👏 #CleantheAir in hospitals and schools!👏 www.sciencedirect.com/science/arti...

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.

"I'm sick of chasing sick buildings." Have a quick listen to this one part of my TEDx talk where I list the types of calls I get *every single day* (and why, for the first time in my career, I'm optimistic about the beginning of the end of the sick building era.) www.youtube.com/watch?v=7W33...

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.

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. #Caturday #asthma

Ready for the holidays 🎄🎅🏻

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.

To help you understand the importance of good ventilation in a building, we strongly recommend this superbly well-designed and very clear website of @raeng.org.uk . Everything is very well explained. A reference site. explainers.raeng.org.uk/ventilation-...

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...

“due to the changing climate school closures could also be triggered by elements like heatwaves, smog or wildfires. As a result we need to plan for future school buildings to be able to provide a healthy indoor climate for learning, in a resilient manner, resisting extreme weather & hazard events” 🌍

Great to see children learning about #AirQuality on #WorldVentil8Day Thank you @cleanairwhere.bsky.social and Lessness Primary School for raising awareness and sharing live air quality readings on the Smart Air dashboard

Some hints and tips about ventilating your home to mark #WorldVentil8Day eps.leeds.ac.uk/news/article...

Welcome, and good to see so many new but familiar faces. Below is a custom feed of posts related to cleaner indoor air emphasising infection control. Took a bit of work to tailor inclusion and exclusions. Always happy to receive feedback to make it better. bsky.app/profile/did:...

If you are using a CO2 monitor to examine your ventilation remember: A difference between 750 and 850 ppm is not a big deal. Activity level, # people, calibration all impact values. You are looking for a difference between 750 and 3000 ppm. Find the bad rooms! #WorldVentil8Day

Due to fireworks and local wood burning, the PM2.5 levels have been around 20 µg/m3 all week The WHO guidelines state that annual average concentrations of PM2.5 should not exceed 5 µg/m3, while 24-hour average exposures should not exceed 15 µg/m3 more than 3 - 4 days per year🧵

In a study in Finnish daycare centers, researchers found that air purifiers decreased children's illnesses by as much as 18.2 percent. We must pass legislation that incentivizes and requires clean indoor air. yle-fi.translate.goog/a/74-2008967...

We know that managing indoor air quality can improve people’s health, but how do you get started?

Did you know bonfire night and Diwali are some of the most polluted nights of the year? Fireworks create fine particles which can take a few days to clear, and aggravate symptoms of those with lung conditions #RememberRemember #WorldVentil8Day #BreatheBetterLiveBetter #Fireworks t.co/np0UVho5Kh

Sick building syndrome (SBS) is a condition in which people develop symptoms of illness or become infected with chronic disease from the building in which they work or reside. Improving ventilation can reduce or resolve symptoms of SBS. #WorldVentilateDay #OpenTheWindows #SickBuildingSyndrome
