If you’re looking for a HRV for your home, Fantech have some good units that I’ve used in past architectural projects. This one is for a small room, I am thinking about putting it into my van to control internal humidity, CO₂ and VOCs. Overkill maybe #airQuality

It's time to start digging in to my mask project!

I need good, solid resources to back up a presentation I'll be giving to the local public. What are the most reliable and ethical doctors, journalists, advocates, research, statistics, or sites that you've seen?

I'll be talking about air quality, advocating environmental justice through citizen science and mutual aid, and my focus is going to be ventilation and masking.

The program is organized by a local group of folks that started putting up air sensors all over town because of toxic chemical leaks from nearby refineries. They got a grant through a university, and they may be able to help me out in getting an air quality sensor so I can test the CO2 in local buildings. I'd also like to be able to pass out some mask samples. I've been trying to find info on other things like sip valves, elastomeric respirator exhaust valve filter adapters, good sites to buy masks and so on.

Since these issues got politicized and the CDC and WHO are increasingly corrupt/hamstrung, finding good info is a fuckin MESS. I could really use some help!

What's been very interesting to me is, the folks who promote masking are usually ALSO right on other issues. Masks are required at the local anarchist book fairs, for example, which to me says a LOT. The people I follow here on Mastodon who are solidly against genocide, fascism, capitalism, and lesser evilism are the SAME people who are solidly for issues like universal healthcare, right to repair, accessibility, direct action, labor organizing, etc etc-- you have a moral consistency that inspires my respect and hope, and I want to learn more from you!

Next post below will be where I list the sources I've collected, updating as I go.

Holy N95, Batman!

Hopefully the ventilation in this A340-300 improves when we are underway.

In LA, cooking emissions rival fossil fuels as ozone pollution source

https://phys.org/news/2025-03-la-cooking-emissions-rival-fossil.html

Over half of US states get more electricity from #cleanenergy than coal.

28 states total, including:

Oklahoma
Kansas
South Dakota

Coal is the worst #fossilfuel for environment (and public health). 20 years ago, over half of US electricity came from coal.

Once again: clean energy investment and policy helps red states, too.

Africa: Air Quality in Africa: Challenges, Impact, and Innovative Monitoring Solutions: [InfoWire] Africa is facing an increasingly urgent crisis in air quality, leading to devastating effects on the public health and the environment. Due to the continent's rapid urbanization and industrialization, harmful pollutants are found in living areas like schools and work environments.

Air quality monitoring on the go! Bruce from Vancouver has been using his co2.click sensor on public transit and in healthcare settings to stay informed about the air he’s breathing.

He shared some great constructive feedback—wishing the button placement was different and considering a DIY protective cover (bicycle inner tube, anyone? ). We love hearing how our sensors are used in the real world and turning feedback into action!

Bruce’s suggestions are now on our list of improvements as we continue refining our designs. Got a creative mod or suggestion? Drop it in the comments!

A local ordinance has banned grass burning because it poisons the air and kills insects, and there are organic waste bins on every corner. Unfortunately, the effect is just the opposite. People who aren't selfish idiots didn't burn grass even before, and the rest burn even more now to show that they aren't obedient sheep and that no one is going to take away their freedom to poison the air for their neighbors.

This graph shows what it does to the #airquality. It immediately jumps from OK to unhealthy.

London Begins to Breathe Better

[Read on Ethical Revolution]

A study by the Greater London Authority has shown that the city’s levels of lethal pollutants have substantially decreased since the expansion of the UK capital’s ultra low emission zone (Ulez).

The London-wide zone covers nine million people across 1500 km2, the world’s largest zone of its kind. 

The report shows that not only have deprived areas seen some of the biggest improvements but air quality has improved in all areas and at a faster rate than the rest of the country.

Nitrogen dioxide is down 27% since Ulez first came in in 2019. PM2.5’s (small particle emissions) are down 31% in outer London compared to what would have been without the Ulez expansion.

Speaking to the Guardian, Mayor of London, Sadiq Khan said, “When I was first elected, evidence showed it would take 193 years to bring London’s air pollution within legal limits if the current efforts continued. However, due to our transformative policies we are now close to achieving it this year.”
