When There’s Smoke, Getting Indoors Isn’t Enough

Some interiors are quite protected from air pollution. Others aren’t.

As the Northeast endures one of the worst wildfire days in recent history, the advice has been pretty simple: stay indoors, filter your air. And chances are, people who can follow this advice are getting it.

Marshall Burke, an economist at the Stanford Doerr School of Sustainability who has been remarkably helpful to this publication, has looked at past examples of severe smoke events and found there isn’t any big demographic gaps in who is seeking out information about what’s going on and how to respond. “On days like this, we actually see evidence that most folks are seeking out information,” Burke told me, “We can look at Google searches in English, we can look at Spanish, we can look in different zip codes. And we see pretty similar searches. Folks notice that things are bad, and they search for information.”

What people can do with that information is where the disparities start to show up.

There are essentially two levels of response to the kind of smoke New York is experiencing now or California has experienced in the past few years: whether you’re inside or outside, and what’s happening to the air inside your home or another building.

Burke’s research has shown that even indoor air quality can still be quite bad during a wildfire — something that is at least anecdotally confirmed today (I am writing this from my bedroom. My office and living room have older, leakier windows and have been abandoned to the smoke).

“Indoors, especially at the levels that New York City is seeing today, you'll see substantial infiltration of smoke into indoor environments. And so you need active mechanical filtration to get the rest of that smoke out,” Burke said.

Citing data from indoor air monitors sold by Purple, which then creates maps of air quality, Burke warned that “right now in New York, I was just looking, they're quite high,” referring to particulate concentration, “so I think that should make us pretty worried about how much of this stuff gets inside and for those who can to really double down on filtration.”

That’s typically achieved by buying air filters, which can run up to hundreds of dollars per device and may require multiple devices in a single home. There can also be runs on these devices during smoke events. My local hardware store, for example, was out of them and Amazon wasn’t delivering several recommended brands until Friday.

  • When Burke and a team of researchers analyzed air quality data in the Bay Area in 2020, they found that concentrations of particulate matter inside homes were not related to how smokey it was outside. The homes they looked at "experienced nearly identical daily outdoor concentrations" on bad smoke days, but indoor pollution was "starkly different." Some homes saw concentrations of particulates more than five times the World Health Organization recommended limit while others were able to keep the concentration levels at one third the WHO limit.

    Burke and the researchers found that wealthier households “can more easily stay home, are more likely to seek information on protective technology, and are more likely to own indoor pollution monitors.” In short, the public health advice you’re hearing now from elected officials is more likely to be followed — and easier to follow — for the wealthy.

    Burke pointed to programs in California that provide air filters to low-income households as well as to ways people could construct their own filters. All you need is a fan and some MERV filters. “it works surprisingly well,” Burke said.

    He also pointed to the need to outfit schools and homeless shelters with filtration. “We're going to need to make those investments. Of course, we can't do that today. But this will happen again, and we could be more prepared.”

    If Natron Couldn’t Make Batteries in the U.S., Can Anyone?

    The failure of the once-promising sodium-ion manufacturer caused a chill among industry observers. But its problems may have been more its own.

    When the promising and well funded sodium-ion battery company Natron Energy announced that it was shutting down operations a few weeks ago, early post-mortems pinned its failure on the challenge of finding a viable market for this alternate battery chemistry. Some went so far as to foreclose on the possibility of manufacturing batteries in the U.S. for the time being.

    But that’s not the takeaway for many industry insiders — including some who are skeptical of sodium-ion’s market potential. Adrian Yao, for instance, is the founder of the lithium-ion battery company EnPower and current PhD student in materials science and engineering at Stanford. He authored a paper earlier this year outlining the many unresolved hurdles these batteries must clear to compete with lithium-iron-phosphate batteries, also known as LFP. A cheaper, more efficient variant on the standard lithium-ion chemistry, LFP has started to overtake the dominant lithium-ion chemistry in the electric vehicle sector, and is now the dominant technology for energy storage systems.

    For EVs, Charging Speed Is the New Range

    They may not refuel as quickly as gas cars, but it’s getting faster all the time to recharge an electric car.

    A family of four pulls their Hyundai Ioniq 5 into a roadside stop, plugs in, and sits down to order some food. By the time it arrives, they realize their EV has added enough charge that they can continue their journey. Instead of eating a leisurely meal, they get their grub to go and jump back in the car.

    The message of this ad, which ran incessantly on some of my streaming services this summer, is a telling evolution in how EVs are marketed. The game-changing feature is not power or range, but rather charging speed, which gets the EV driver back on the road quickly rather than forcing them to find new and creative ways to kill time until the battery is ready. Marketing now frequently highlights an electric car’s ability to add a whole lot of miles in just 15 to 20 minutes of charge time.

    The White House Office of Management and Budget directed federal agencies to prepare to reduce personnel during a potential government shutdown, targeting employees who work for programs that are not legally required to continue, Politico reported Wednesday, citing a memo from the agency.
