Where do you live?
I can understand wanting to monitor air quality on the West Coast, where you are plagued by forest fires.
Here on the East Coast, I do worry about air quality, but I never look it up.
I just assume I’m fine unless I am in the city, on a crowded freeway, or stuck behind the wrong truck - and I just avoid those situations if I can.
On the other hand, if it’s allergies I’m worried about - I can feel right away if it’s an extra bad pollen day without looking it up - and it doesn’t really affect my behavior much anyway. I just suffer a little more when I mow the lawn and reward myself with a beer.
The trouble is, I might be a little allergic to the hops in beer too. :-(

The pollen/allergy count is important to those of us with allergies, (which might be about everyone.)
As you noted air quality if you live within a hundred miles from the ocean is a waste of time and money most days with our powerful sea breezes.
With major forest fires, you don’t need a service to tell you there is smoke in the skies and to try to avoid breathing it by staying indoors and wearing a good N95 mask or a damp bandanna over your nose and mouth while outside.
