Airmega 200M has a display-shutoff feature that lets you dim its lights, something we value highly for bedroom use. The Airmega 200M has a square grille rather than a round one—but that’s the only major physical difference. If you prefer the Airmega 200M’s looks or if you find it at a better price, we recommend it just as highly.
