I have one of those small portable ones that's designed to take with you on a plane so that's been chugging away on my desk. And I cracked the window a bit for the fresh air.

My biggest worry is that they've been asleep on the couch since yesterday morning - not unusual behaviour with their other health issues - and I've been just walking around the house like normal, so there's no way of knowing how long they've been sick & infectious. I have been masking while the contractors are in the house so I might be ok, but it's probably too early to know for sure.
