Have you thought about setting up a cheap 20x20 box fan with a HEPA filter in your home/apartment (California Wildfire Setup), air quality can be worse inside. It may be able to create an environment where you can recover a little everyday.

Here is a demonstration

I myself run one in my home but just place the filter behind and against the fan allowing the airflow to keep it in place.

Works wonders and I can see a noticeable difference in air quality and sleep (allergens, odors, etc)

A 20x20 fan DIY was actually on my todo list. This is the first time I've seen a box with multiple filters on it, however -- all the ones I saw before just taped a single filter to the fan. Are the multiple filters a big practical improvement?

(I used to own an expensive air filter that was top-rated by Consumer Reports at the time, but sold it during a minimalism phase. Now I want to try a filter again, this pollen season, but more frugally.)
