左は13時ごろの三田線。水道橋駅付近。ガラガラで席半分しか埋まってないのにけっこう高い。窓開けは私が開けた１か所。
右は19時前の丸の内線。大手町駅付近。ちょっと混んでてこの高さ。

Kid's backpack #CovidCO2 measurements for a week. What's the difference that made it better? March break. No school.

Left: 2500 ppm from riding the school bus. High mid-day values 1200 ppm from an undersized ventilation system.

Right: 600-900 ppm in our home.

Amtrak What is the ventilation or filtration like on Amtrak? Anyone have CO₂ or other #IAQ readings?

The COVID CO₂ map Adrian Cummins 🇮🇪🇪🇺 Not many in #Ireland !

And its done. New legislation passed in 🇫🇷 that foresees mandatory CO2 monitoring of indoor spaces. Starting with schools, daycare, restaurants. Bravo 👏

First time in church with a CO2 monitor ... this seems not good, right?

Trams in Milan and ventilation 🤢

With growing pollution 🏭 awareness, #CO2 regulation is increasingly common. New #French regulations now protect 🛡️ schools, daycares, restaurants, and more. Here’s to a healthier tomorrow 🌞. #covidCO2 #CO2 Warrior

Joey Fox .Mike Anderson Please do a story on this! The new ASHRAE document out for review. 24 ACH for places of worship. We are barely getting 0.5 ACH with the dozens of buildings we have tested. See Page 5 (L/s/person = 15 ~24ACH) Liesl McConchie #COVIDCO2

Today in a Mount Sinai Health System outpatient clinic: Zero masks on front desk staff. Zero masks on any nurses or doctors that I could see. Waiting room filled with elderly people, some with assistive walking devices, few wearing masks. #CO2 hit 1366. Shameful. #KeepMasksInHealthcare

Keep it comfy wherever you go with EcoFlow's WAVE 2. It runs wirelessly for up to 8 hours and can be charged quickly via AC, solar, cars, or power stations.

I sell a wide range of vintage #collectables including #Irishcoins . These include half crowns, florins, shillings, sixpences and threepences. Many of these are 75% silver.

kanchan 🍿 Royal Canadian C.C. Aranet Raven CleanAir Map I've never seen such a bad air quality number! OMG #covidco2 #COVIDIsAirborne

For reference, something I typed up last year to explain to others the benefits of CO2 monitors in assessing COVID risk in spaces. Outside air is around 450ppm I’ve found in Vancouver. The lower the number, the better. #BCCO2 #COVIDCO2

First time on an airplane in 5 years...CO2 levels in the airport and im the air were not so bad. CO2 levels right before takeoff and right after landing were pretty horrendous.

九州のCO2を測定する知人が、皆に注意喚起してくれと。西鉄バス、混雑、窓開け運転席のみ、ドアのすきま風入るところでこの数字と。
さらに換気悪い後ろや奥は怖くていけないと。
1cmでもいいから全部の窓あけてほしいそうです。

I recently used my #Aranet4 to test exhaled air concentration (CO2) on TransLink's newest bus: the Nova LFSe+ on route 100.

I was initially impressed. The bus HVAC can quickly exchange fresh air into a fully loaded bus…

But, ONLY when it is on.
