Please build something. If you are clumsy/busy/tired, please just attach a 20”x20”x1” or 4” Merv 13 filter to the back(not where the air gets blown!) using tape or cords. It’s very effective and affordable!

Forest fire smoke in Ontario has cut air temperature 4-5°C than forecast, greatly reducing electricity demand today. You can see the areas with clear sky in Norfolk County near Lake Erie are around 32°C while Toronto is 28°C. Normally Toronto is one or two degrees warmer.

Armwaving AI generated estimates of what to expect inside if the outdoor PM2.5 level is 300mcg/m3. I don't consider our house "clean room" grade, but if we're hovering around 15-20 right now, I guess our investment in air filtration is paying off.
ChatGPT estimates of the kind of indoor PM2.5 levels to expect under various household conditions when the outdoor level is around 300mcg/m3.

Windows open / very leaky home: 240–300+ µg/m³

Closed, leaky home without filtration: 180–250 µg/m³

Average closed home without filtration: 165–180 µg/m³

Tighter home with good HVAC filtration: 90–150 µg/m³

Properly sized HEPA purifier: 50–120 µg/m³

Well-sealed clean room with strong HEPA: potentially <50 µg/m³

Here's our current PM2.5 data starting at 6am this morning. Even with fairly aggressive filtration of our indoor air, you can see the outside conditions (yellow) are starting to pull up the (blue) indoor curve. #onstorm #smoke
Currently the PM2.5 inside is at 17mcg/m3, but outside it's more like 300mcg/m3 and climbing.

15 is the Canadian indoor residential average (non-smoking households).  The Indoor Air Hygiene Institute recommends it stay below 12 with no spikes above 35.

Jay Bhattacharya recently defended his censorship of a CDC vaccine study in one of the most Orwellian articles I’ve ever read. But it revealed a more fundamental problem. He doesn’t realize he’s the medical establishment now. It’s not his job to whine. It’s his job to deliver results.

NASA isn't why the US doesn't have universal healthcare, or a social safety net. The US doesn't have those things because politicians with the power to provide them choose specifically not to (with varying levels of support from voters). Enthusiasm for human spaceflight doesn't drive that choice.
