A simple chart can help compare a range of #AirFilterUnits Calculate cost effectiveness High CADR Low noise Think what's suitable 4 context how many required Use adapter sockets if there is a socket To place more than one Think abt footplate Directn of airflow in winter

Choosing a cost effective & efficient air purifier isnt easy so in partnership with @ThisHouseFresh we are happy to share this new resource made to help start conversations & guide decision making. Further resources can be found in our toolkit at SafeAirSchools.org

Clinically vulnerable patients deserve so much better than this. The UK's NHS hospitals need major investment to improve the ventilation in ALL areas. And to address its Infection Prevention Control policies. #CleanAirInHealthcare 6/

Here, many patients are crammed into prefabricated extensions. They are convalescing in air with CO2 over 1000ppm. There's no amazing air changes there. It is very inconsistent and a big risk of hospital acquired infection, to those people trying to recover. 5/

Unfortunately this amazing air quality is not replicated around other areas of the hospital. The CO2 monitor went off on Dr Ben's ward round. 4/

Theatres with laminar flow can have up to 300 air changes per hour. This is typically used in orthopaedic surgery. The risk of infection is particularly high when you're putting bits of metal deep inside the body. It's expensive to correct & obviously bad for the patient. 3/

The risk of infection is high when you open up people's bodies. So the air must be as pristine as possible. I listened to a podcast with a hospital designer talking; standard surgical theatres have around 22 air changes per hour. 2/

My partner is an anaesthetist. He took a CO2 monitor into work this week; the air quality inside surgical theatres is probably the best on the planet. However, other areas of a hospital can have very poor air quality... 1/

🇪🇸 Study Passive Ventilation Strategies Such as 🪟 openings Proved insufficient, emphasizing the need for Controlled Mechanical Ventilation To ensure consistent air renewal maintaining thermal comfort x.com/MA_Campano/sta…

Opening windows alone wasn’t enough to maintain safe air quality. 🌬️ Our findings emphasize the need for Controlled Mechanical Ventilation (CMV) to provide fresh air while keeping rooms comfortable. 3/9

#CleanAirIndoors 🧵 1/6 Every room needs a health check. Is it breathing ok? What to do? USE A CO2 monitor 🚦 How well is the old indoor stale breathed out CO2 Air replaced by the outside 'Fresh'Air? 🟢CO2<800ppm recommended @Orla_Hegarty explains twitter.com/Orla_Hegarty/s…

🚦 CO2 (carbon dioxide) monitors are in schools to measure exhaled air. (They don’t measure virus) ..the more people breathing, the more CO2 build up .. the more exhaled air, the more chance of inhaling virus particles So more clean air & fewer people reduces the risks 2/

"...5 µg/m3 increase in PM2.5 and PM10 was associated with a decrease of 0.99 and 0.46 in GPA, respectively. Notably, these negative associations were more pronounced in mathematics and natural sciences compared to language-related subjects."

Children and air pollution 👇 If PM2.5 levels go up by 5 µg/m³, students' GPA can drop by as much as 1 point. This is especially true for subjects like math and science. Girls and #children with non-Danish mothers are more likely to be affected by the effects of #airpollution.
