Would anyone care to recommend a CO2 monitor I can prop up next to my desk to remind me when to ventilate?
Bonus marks if it's both powered and portable, so I can occasionally take it to meetings and opt out when things get too muggy. I don't care about recording numbers over time. UK purchase.
Are there online resources to figure out why air quality is bad?

Smoke signals
One of India’s most pressing environmental issues is air quality. A global report from air monitoring firm IQAir, published last week, found that a stunning 83 of the 100 worst polluted cities in the world are in India, with Delhi named as the most polluted capital city having averaged a PM2.5 of 102.1 µg/m3 in 2023.
While Bangladesh and Pakistan were named as the most and second-most polluted nations overall, India was third, with an annualized average concentration of fine particulate matter (PM2.5) measuring 54.4 µg/m3 last year — more than 10x the WHO guideline of 5 µg/m3.
Very high #SaharanDust concentrations predicted to continue this weekend for the Iberian Peninsula by #CopernicusAtmosphere regional forecast. Stay informed about possible hazards with your national and local #airquality services.
Changed out the Corsi Rosenthal filters at the house... this is not filter material, this is a thick layer of drywall dust. Wore an N95 and removed these outside, it was nasty. 😬 #aqi#airquality#PM2point5
A Swiss air quality monitoring firm on Tuesday said its latest worldwide data reveals the need for more walkable cities and a swift transition away from planet-heating fossil fuels, as just 7 out of 134 countries were found to meet global standards for dangerous air pollution.
New research found that >10% of countries & territories met #WorldHealthOrganization guidelines for particulate matter #pollution last year.
Only 10 countries & territories out of 134 achieved the #WHO’s standards for a pervasive form of #AirPollution last year, acc/to #AirQuality data compiled by IQAir, a Swiss company.
The #WorldHealthOrganization sets a guideline that people shouldn’t breathe more than 5 micrograms of #FineParticulateMatter per cubic meter of #air, on average, throughout a year. The #UnitedStates#EPA recently proposed tightening its standard from 12 to 9 micrograms per cubic meter.
The world’s 100 worst polluted cities are in Asia — and 83 of them are in just one country
Only 10 countries and territories had “healthy” air quality: Finland, Estonia, Puerto Rico, Australia, New Zealand, Bermuda, Grenada, Iceland, Mauritius and French Polynesia.
Having a look at the IQAir World Air Quality Report for 2023. Only 7 countries in the world scored below the limit value for safe levels of particulate matter: Australia, Estonia, Finland, Grenada, Iceland, Mauritius and Aotearoa/New Zealand. Asia, particularly cities in South Asia (Bangladesh, India, and Pakistan) are at the bottom of the chart, with yearly averages up to 23 times the limit value. #AirQuality#Environment#Pollution#Health https://www.iqair.com/world-air-quality-ranking

Question: Anyone who specializes in indoor air quality able to take a look at something? Used @cleanairstars tool to ask for filters for a classroom and was told it's not needed bc HVAC is ASHRAE 62.1. Thanks!
Best way to hook up a #solarpanel connected to an #airquality station? I have it currently hooked up direct, but the panel is draining the battery, so it doesn't even last the evening.
