@joefilter.bsky.socialThe AZ heat is almost over! Time to let your home breathe and check your ducts to see if they need a good cleaning. Air duct cleaning is a great way to help improve your indoor air quality after dust storms and a stuffy summer.

@onschoolsafety.bsky.socialWhat happens outside impacts what happens inside classrooms and on the school bus.
On International Day for Clean Air for blue skies, let's talk about indoor air. It can be far more polluted than outdoor air and speed up the transmission of airborne viruses.

Luft messen ist fĂŒr den Einzelnen keine Rocket Science mehr
Simple, genaue MessgerĂ€te gibt es lĂ€ngst ab ~40 âŹ
Wir atmen COâ aus. Je höher der Wert, desto mehr ausgeatmete Luft ist im Raum
~420 ppm drauĂen
ab 800 ppm lĂŒften
ab 1.400 ppm ungesund
Lösung, wo wir Einfluss haben: LĂŒften

Warum ist das relevant?
Gute Raumluft bedeutet weniger Airborne Infektionen (=KrankenstandâŹïž), mehr Konzentration, weniger Kopfweh etc
Asthma + Allergien etwa können durch schlechte Luft stÀrker werden
Dass neben Vorschriften auch breites Bewusstsein fehlt, ist Public Health Versagen
@sonjahartl7.eurosky.social1/5
Heute ist UN #CleanAirDay
Angenommen, fĂŒr Trinkwasser + Lebensmittel gĂ€be es plötzlich keine verbindlichen Regeln mehr.
Unvorstellbar.
Bei #Innenraumluft ist das RealitÀt: Wir atmen ~11.000 l Luft/Tag, verbringen ~90 % unserer Zeit drinnen + teilen diese Luft meist mit anderen
@igoe.atInnenraumluft findet zunehmend Beachtung, auch international, hier aus UK

@mjnabuurs.bsky.socialPlease, please ensure these cars are equipped with optimum ventilation and filtration.
The amount of sickness shared on Via trains is assumed to be quite high because of how poor the IAQ measurements are on many of @viarailcanada.bsky.socialâs cars.
Great #IAQ also improves cognition.
