Summer is almost upon us, and Canada is already on fire, so I guess it's time to share this again: my guide to the dangers of smoke, why you *really* don't want to breathe it, and how to get your air purifier situation set up before the smoke comes.

@susankayequinn FYI, your estimate for CR box filters are about double what they should be. Home Depot reliably sells 20x20 MERV-13* filters for $20-$25 _individually_, but if you buy in bulk (4 or more), they're half the cost. And if you're buying for a CR box, you're buying in bulk. That puts your filter replacement costs at $50 rather than $100. That's a general trend - bulk filters are cheaper.
* they list them as "FPR 10" and "FPR 12"; both are labeled MERV-13 equivalent
