Germany - Indoor Air Quality Guidelines advise that the average CO2ppm level should not exceed 1000ppm during a unit of use (e.g. a class period). https://t.co/fiEPMyf2g5 #CleanAirClassrooms

Prioritising clean air in schools means fewer sick days, better focus, & healthier kids. Clean air tools like the Blast air purifier help make classrooms safer so every child can learn, grow, and thrive worry-free. 🏫💚 Every child deserves clean air. Let’s make it standard.

Did you know there is an association between exposure to #AirPollution and risk of #MentalIllnesses? Depression and cognitive impairment are particularly possible, but self-harm, suicide, anxiety and other effects are also risks. For more info: https://t.co/ttc5wc5P0n

New review: poor indoor air in U.S. schools causes students to miss ~14 M school days each year due to asthma. Installing HEPA‑grade air filters + real‑time CO₂ monitors in classrooms can cut absences by up to 40% and boost test scores by as much as 10%. @EPA @EDGov @CDCgov

Imagine how much of a healthier environment a student would have if there was a PZAP ( personal zone air purifier) installed above their desk

A group of NZ doctors, teachers and academics etc., have written an open letter to the Government requesting C02 monitors, air purifiers, free tests, paid leave and recognition of LongCOVID as an occupational hazard, saying too many children & educators are still getting Covid.

We posted the levels live on the website and customers could scan the code by the entrance before they entered. It definitely improved our business as customers and staff was kept safe

@EmJayNabuurs @airspothealth NL mandated CO2 monitors in classrooms in 2022, but did nothing more than that. Those colour coded CO2 charts are nothing more than window dressing. No one is paying any attention to CO2. The monitors are often not plugged in. If they are, no one checks or even understands them

To celebrate #AirQualityAwarenessWeek, we'll be sharing a tip daily! Today's tip is: Use a free air quality app (like Clean Air in Cities) to check pollution levels every morning just like you would with the weather. So, you can plan your outdoor activities accordingly!

You're not gonna believe this... --> silicosis is a lung disease caused by tiny cyrstalline particles --> this is a particular risk for miners --> MSHA (Mine Safety and Health Admin) has what's called the 'silica rule' to protect workers --> it's being temporarily suspended...

New hospital study: air purifiers cut airborne COVID by 98%. Rooms with HEPA ventilation had zero virus detected. Clean air is essential public health infrastructure — not a luxury. Study: https://t.co/eVdkFlXEEN…

For folks nervous about travelling to the US from Europe or Asia, consider connecting via Canada. You clear US customs on 🇨🇦 soil, if you're denied entry you get to go back to Canada (and back home) instead of some black site. Or just cancel your US trip and visit 🇨🇦 instead!

I’ve been strongly anti-Trump on social media. Would it be dangerous to travel to America right now for a holiday?
