I'd like to buy a recirculating cooker hood that can just go under a line of

here, pls?

I always assumed the recirculating ones were there primarily for
decoration rather than function (the big flashy chimney ones
typically). If you want one which doesn't extract steam and fumes, and
which you can't really see either, I can't help wondering why you'd
bother?
