>I'm not looking forward to any smoke now my dad has COPD, IPF, is on oxygen, and he's elderly. If we get any amount of smoke here it will be the end of him. It's hard enough trying to keep him from contracting SARS-Cov-2 and developing covid-19 Seriously, get a HEPA rated air filter. Speaking as someone who has some serious lung issues, it's literally life changing/saving. Honeywell sells a number of models, cost is…

If you have central heat you can sometimes configure the thermostat to run the blower separately from the heating element. This creates a nice positive pressure environment. If you have a MERV 10 or better filter installed on the furnace then it's actually pulling in filtered air, as any high enough MERV filter will filter PM2.5 with a decent efficiency. I think they start filtering PM2.5 at about MERV 10, and by MER…

Also something to consider: electrostatic in-line filtering, which generally combines electrostatic cells plus 2 levels of filters

Meanwhile, in Sao Paulo we are getting to 34C (93F) every day, and even the nights have been extremely warm. And here at the southern hemisphere it's winter now.

In September? Wow. It should be warming, with those crazy days you leave the house ready for 4 seasons. 34C is nuts.

Would be curious to compare how much CO2 has been emitted as a result of these fires to California’s annual CO2 savings by going for renewable energy.

That might be interesting from a purely educational point of view but it is of little practical relevance. Trees burning in wild fires release CO2 that was captured in the last couple of decades by the tree in the process of growing. Burning fossil fuels releases CO2 which was captured millennia ago and buried deep underground. It's roughly the same as why melting icebergs cause sea levels to rise but rain will not.

Not to mention the fact that California is still emitting far more CO2 then it should in order to keep the climate disaster at bay.

Any comparison between current carbon savings and emissions of natural disaster would be an exercise in irrelevance.

Why not order a few HEPA filter air purifiers? I have 4 (5th is on its way). They work extremely well and if you pair them with a Temptop AQI sensor you can see how well in real time: https://www.temtopus.com/collections/temtopus-pm2-5-pm10-mon... Those temptop sensors are great. I've previously had awair, foobot, and purple sensors which all sucked in different ways. Really long thread about this here: https://www.r…

I refuse to believe that all air filtering fans on Amazon are sold out, especially considering their extreme popularity in countries all over Asia. And even if we assume that’s the case for the sake of argument, you can still buy N95 particle masks of many different brands which will protect you well from particles in the air. They also mostly protect you from viruses. There was a pretty massive supply shortage of them this spring at the start of the pandemic but I doubt they’re extremely difficult to get a hold of today, I have five in my kitchen that I bought online for about a dollar each.

Why in the world would this be a native app and not a web page?

And what a strange name. Why is “shoot” treated like an expletive? I’m actually not even sure I’m parsing the name correctly.

Shoot! is a common substitute for other, more abrasive expletives (Shit! Fuck!). I'd much rather have the former in a business/service name!

Interestingly, the Android package name is indeed com.shitismoke.app

On the day when the Bay Area was completely blacked out, the weather forecast said it would be 89, and when I went outside my thermometer was reading 68. The cooling effect of smoke is ridiculous.

Yeah, we had several days in Seattle where the forecast was 70s and sunny yet it stayed 58F all day and night.

Sold out until this Friday when this is all supposed to be over, unless it's a very weak filter that won't do anything for smoke. Show me where you can get genuine N95 masks (as a non-essential worker) as well please. There are tons of counterfeit masks going around.

I’m in the midsts of this right now and it’s depressing. I spent yesterday morning with a sore throat and itchy eyes and most of the afternoon hopelessly driving hours away for a box fan and furnace filter (I finally found them). All the while I should have been working. Some of my coworkers have complained of week-long headaches. If anyone else is suffering from this: you are not alone.

I’ve been using an app that converts AQI to equivalent cigarettes smoked per day. It’s not perfect but it’s something I can wrap my head around as a meaningfully bad number.

I'd really rather not download a whole app for this so my apologies if this answer is readily available in the app, but...

I keep seeing these kinds of conversions (AQI to equivalent cigarettes per day) but I never see numbers on how long you need to be outside for that to be the case. Is it based on assuming someone on the coast (where AC is rare) having to keep their windows open all day? Is it based on 1-2 trips outside per day? How does it incorporate exposure time into the conversion rate?

Coal smoke in that case, not wood smoke. Coal is a terrible pollutant. If you survive the wood smoke, the literature suggests you'll be back to normal in a couple weeks.

I would make the educated guess that the reason wood smoke is OK is because we have thousands of years of evolution to be more tolerant of wood smoke.

You would hope, but no. Wood smoke is still deadly.[0]

Close to a million years by the best guess.

Which is thousands of years... about a thousand such thousands.
