I found a round brown filter in my driveway when I drove back home after running errands.

Is there any chance this thing fell off my car?

I have a mechanic appointment booked next week for regular service and wonder if I’m safe just driving around until then.

    I have no idea what to look for. I’m not sure I’d be able to ascertain if anything was missing.

        I can’t know for certain, but judging by the comment OP posted, I don’t think they’re in a position to say.

        I had a look at the user manual and was able to confirm via YouTube video that the HRV filter is very different. Flat and rectangular. What I found seems to be a garden variety shop vac filter.
