No filter... this is how I look on Zoom with a window to my right vs facing a window. Is that a game changer, or what?!
I'm sure you want your students to be able to see you well so before you get too settled into your classroom layout, I'd literally take your computer or phone and see how you look from different angles in your room.
Chances are very good you want to be looking straight out a window. And BONUS- the view and extra sunshine for you can be nice, too!
If you can't work by a window, experiment with other lamps and lighting to find what makes you show up best for the kids.
And while we're on the topic of looking good, check out the Zoom setting (under Video) that lets you "touch up my appearance." I mean, why not, right? :)
