Amazon still has this one in stock with Prime, at least for me https://www.amazon.com/dp/B07D58KJ28/ref=cm_sw_r_cp_apa_i_7RtrFbNXSR459
I got it a couple years ago for California wildfires and I’ve been happy with it. I’m sure it doesn’t compare to the medical grade filters, but its a certified HEPA filter, and it cleans the air well enough that when I do go outside I immediately can tell the difference and smell the smoke.
