> I mean you can put regulations on anything to make it sure it is doing what it is supposed to be, right?

Yes, and when it comes to selling health-related products, the standards are higher than, say, entertainment devices. For very good reason.

> The harm caused by the lack of a super cheap and effective air filter, especially in CA where we can get smoked out for weeks due to fires could be greater than the harm reduced by the regulation.

That's not clear to me. I know lots of people with air filters, and they all chose them based on aesthetic judgements. I doubt any of them would've acted differently if it was $5 cheaper (from certification)

Also, you can still just buy a box fan ($30) and tape a filter ($10) to it and hope for the best in terms of air purification. You just can't pay someone else $70 to sell you that, unless they run a test to prove it works. Doesn't seem like a big deal.
