Why Round Vents?

The purpose of round vents is highlighted in situations where space is limited. Without hard corners, round vents are able to fit where their rectangular counterparts can not. Furthermore, some may find that the round design is more appropriate for the visual style they are aiming for. And with just as much efficacy as rectangular vents, you can rest easy knowing you're not losing out on quality.
