Auch nach dem #Worldventil8day am 8. November gilt weiterhin, dass wir durch CO2-Messen mit mobilen Messgeräten jene Räume identifizieren können, wo guter Luftwechsel stattfindet.

Wichtig für Gesundheit, Konzentration und Wohlbefinden.

Gerne könnt ihr weiter CO2-Messergebnisse mit uns teilen.

Als Verein INITIATIVE GESUNDES ÖSTERREICH setzen wir uns für #saubereLuft an Schulen, in Geschäften, Arztpraxen und allen öffentlichen Räumen ein.

Auch Zuhause hilft ein CO2-Messgerät beim Lüften: Man schläft viel besser bei 800 ppm als bei 3000 ppm, die es bei geschlossenem Fenster oft erreicht.

Got flu problems?

Try this.
To be used with masks as part of a complete strategy. Safer Indoor Air for Kids Mechanically OR Naturally Ventilated? • schools • out of hours care • day-care • youth groups • clubs • anywhere kids get together Mechanically Ventilated Call a mechanical engineer to review the HVAC system. C02 Monitors LOW RELATIVE RISK • Below 800ppm/ MODERATE RELATIVE RISK • 800-1500 ppm • work to improve indoor air quality to low relative risk range HIGH RELATIVE RISK • Above 1500 ppm • moderate risk reading not improving • Leave room until air quality improved, • Increase ventilation bringing outdoor air indoors. • Use HEPA filters with ventilation to assist if occurs repeatedly. • Reduce occupancy or cease activity causing high risk air quality. Naturally Ventilated Open windows and doors where it is safe to do so. Complete the recommended work to increase outdoor air intake. Once the building is in use, monitor the ventilation with CO2 monitors. Work to create a cross breeze of fresh air. On still days may use a child safe fan." Use Portable HEPA filters if ventilation is not enough. Portable HEPA filters • Use filtration to clean the air, do not add anything to the air. • Use the right size and avoid low flow settings. • CADR = clean air delivery rate • Aim for an equivalent of minimum 6 air changes per hour (ACHe) • ACHe X Room volume = CADR needed • Use of more filters may allow for less noise. • HEPA filters will not lower the CO2 reading on the monitor. *Fans, if used, must be ploced to direct indoor air outside & encouroge cross ventilation. Take core not to recirculate, including avoiding the use of split system air-conditioning For more detailed odvice & warnings please see OzAGE document for Safe Indoor Air. While the building is in use monitor the ventilation with CO2 monitors. Use Portable HEPA filters if ventilation is not enough, outdoor air is polluted or bad weather OZSAGE

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.

Reminders, as public health officials warn of a very bad flu season:

🧵

* Washing hands is not a strategy for a respiratory virus. N95s, ventilation, air filtration -- especially in hospitals.

* We should have been cleaning indoor air with the same effort we put into cleaning drinking water.

Die Grippesaison beginnt und die Zahl der Krankenstände steigt. Doch es könnte so einfach sein Infektionen zu reduzieren:
#Lüften bzw. #Lüftungsanlagen hochdrehen und #CO2-Monitoring, um den Erfolg zu überprüfen.

Zusätzlich in bestimmten Situationen wie Arztpraxen #HEPA-Luftreiniger.

Was hier für Irland gefordert wird, müssen wir auch in Österreich endlich erreichen

The sooner the Irish State addresses our lack of ventilation infrastructure in our public transport and schools, the better for everyone, especially children. The cycle of year-round respiratory infections could end if we improved ventilation in communal spaces.

Have you ever wondered how ventilated a bus on your morning commute is? Or how well ventilated children's classrooms are?

Thanks to the teacher who shared this data with us from their morning commute and first class of the morning, we can see how poorly ventilated these spaces are in Ireland.
Screenshot of airspot CO2 monitor app showing high CO2 ppm through the night rising from a base of 1800ppm to a peak of 3809ppm. Dropping down to 1200 ppm and rising back up to 2800 ppm. Screenshot of airspot CO2 monitor app showing high CO2 ppm through the night rising from a base of 1000ppm in the classroom to a peak of 2800 ppm before going down to 2210.

Aufenthalt in schlecht belüfteten Schulräumen führt auch ganz ohne Betrachtung von Infektionskrankheiten zu schlechterer Konzentrationsfähigkeit und somit vermindertem Lernerfolg!
Alleine schon deshalb wären dauerhaft unter 1000 ppm dringend notwendig.

Fascinating article looking at respiratory viruses in a Swiss school setting finds that bad air quality in the classroom, not close proximity, is the dominant driver of viral spread.

Close proximity: RR 1.16
Shared classroom: RR 3.17
Suboptimal air quality: 1.90

Zum Infektionsschutz innerhalb der Familie angeschafft, hilft ein HEPA-Luftreiniger auch gut gegen Feinstaub, Pollen und Hausstaub.

Wer es ausprobiert hat, will es nicht mehr missen.
Ein Luftreiniger der Firma Trotec steht an einer Zimmerwand. Die Anzeige zeigt die ausgezeichnete Luftqualität mit zwei hellblauen Leuchtbalkan. Außerdem steht da unter PM 2,5 der Wert 3.

Wir haben auch ein ein paar Holzofenfreunde in der Nachbarschaft. Einen Feinstaubsensor bekommt man für kleines Geld. So kann ich das Lüften davon abhängig machen, wie dick die Luft ist. Und die Nachbarn haben auch etwas davon.
