My New Favorite Gadget: A Purple Air Air Quality Monitor
July 9th, 2018 by Susanna Schick
As you know, Los Angeles has the worst air in the nation. It’s gotten a lot better, but until all diesel vehicles are in the scrapyard, among other things, we’re still at risk. A few weeks ago I saw a tweet from the Coalition for Clean Air asking for Torrance, CA, residents to host air quality monitors. I don’t live in Torrance, but do live within cancer distance of the 5 freeway. Victor came over and installed the monitor on my porch, and all I have to host is the electricity and wifi. Now I get to know the air quality, temperature, and humidity right at my front door. Of course on the map, it shows up in a different place for privacy.
The CCA has monitors scattered all over California, to get a more accurate read on our air quality. As its map shows, there are still plenty of gaps — particularly in Carson, Lakewood, and Compton, areas through which the 710 corridor cuts its vile swath of diesel fumes from trucks heading to and from America’s busiest port. If you live in any of the areas lacking monitors on this map, scroll down below the map and sign up to host a monitor. If not, and you still want to help, there’s also a link where you can donate to CCA. This page lists some of its past achievements since the NGO’s birth in 1971. But I think it’s so rad, I’ll paste its historic wins here:
Historic Wins by the Coalition for Clean Air
- Won the nation’s first ban on “perc,” a toxic dry cleaning chemical containing volatile organic compounds, which create smog and threaten human health.
- Sponsored and helped pass the “Pavley” bill (AB 1493) — the first law in the nation to reduce the greenhouse gases emitted from cars — providing the model for the first national emission standards for cars.
- Spearheaded California’s original Smog Check program, which reduces 100 tons of automobile pollution daily.
- Obtained an unprecedented $50 million settlement for air quality and neighborhood improvements, including agreement by the Port of Los Angeles’ China Shipping Terminal to commit nearly 75% of ships to “plug in” to an electrical dock outlet instead of running their engines.
- Persuaded the governor to spend $50 million on cleaner school buses, the South Coast Air Quality Management District to require local agencies to purchase clean vehicles, and both the Los Angeles Unified School District and Metro to clean up their fleets.
- Won a legal victory against major grocery chains, whose operations exposed low-income communities to toxic diesel exhaust; the settlement required large trucking distribution centers to reduce pollution at their facilities and to send health warnings in both Spanish and English to surrounding communities.
The monitors are made by Purple Air, so if you’re not in an area CCA needs to monitor, you can buy one here. Being the clean air nerd that I am, I did some screen shots to show the difference in readouts on a typical summer day in LA and on the 4th of July. Ignore the monitor that reads 702, it’s broken. The readouts even show the confidence rate, and that one has a confidence rate of 40%.
Things get interesting as the fireworks come out. By 10:00PM, the air in LA had gotten pretty dirty…
