Do you have a model in mind? There seem to be a number of different Elicas, some genuine hoods, others more like wall fans.

Here is one of them:

It says "Zephyr" but it is actually by Elica, Zephyr was just the distributor for them.

Compromise is in the nose of the beholder. Will some effluent miss the hood? Probably. Will some effluent not be captured when it hits the hood? Probably. Will flow rate drop with lint and grease accumulation on the mesh? Certainly. Is better performance needed by the OP? This is entirely a matter of personal preference of the OP.

The example hood (well, more of a vent than a hood) will be better than no hood, and better than OTR microwave venting. If the alternative of an optimal hood is never going to be aesthetically acceptable and therefore not bought, then one can conclude that a Zephyr style is a good compromise between not having a hood and not buying a hood.

I was going to suggest Futuro Futuro. My friends have a flat one like that over their island with a gas cooktop, and they like it. It looks like the Futuro Futuros can come with filters over the whole bottom of the hood, so maybe they capture better. OTOH, they appear to be pretty pricey. Here's a link to a random one in case you want to check it out.

I installed one of these alot-of-glass hoods over a 36" induction cooktop but between cabinets which helps funnel goo into the hood. It is a lot of glass. And it works very well. In an island or without side cabinets, I'd want something bigger, but the glass does help catch the stuff you're trying to catch. Don't fear the glass! (So I think you should go for it!)

Elica has some pretty hoods but I could never find any reviews on them. So...buy it and review it. I need to remodel a new kitchen. :)
