You've written quite a bit about using air purifiers for cleaning particulates out of indoor air. What about the MERV filters in the HVAC systems? Seems like they would also be helpful for improving indoor air quality, especially the MERV 12 or MERV 13 ones. But you haven't said anything much about them. Are they dramatically worse than the air purifiers in cleaning particulates out of the air?

I think MERV filters in HVAC systems are great! I haven't looked into them *too* much, so I don't think I can give a detailed summary of the tradeoffs versus a freestanding air purifier. But broadly speaking, I think they're probably a good idea for most people who have a HVAC system, during whatever part of the year they're running it.
(My #1 piece of advice regarding air quality is to get a particle counter. As long as particles are low, you're good!)
