I’m not so sure a central air system wouldn’t be up to the task. I calculate this purifier at 150 CFM from the product page and assuming 8 ft. ceilings, and this implies 1,500 CFM would be a fairly typical residential HVAC system, so that seems roughly adequate to me.
Also, that product page suggests you should cycle air 5 times per hour, but that seems excessive to me. I use that unit in a much larger room on a low setting and it does just fine getting rid of any smoke smell from wildfires.
microcovid.org thinks outside is 1⁄20 the risk of inside, and 5 ACH gets you to 1⁄4.
The purifier you link to has a CADR of 141 CFM, so roughly equivalent to bringing in outside air at a rate of 141 CFM.
If your residential system can do 1,500 CFM on a 2,000 sqft house with 8ft ceilings, I get 5.6 ACH. That’s quite a bit better than I expected; not sure how typical that is?
