Same smart brain — humidity sensor, auto mode, app — in two bodies. The LV600S adds warm mist (sterilizing, slightly warming) and higher output for open living areas. The Classic 300S is cool-mist only, covers a bedroom or office, and is top-fill, which is a real daily convenience. Big room or warm mist wanted: LV600S. Bedroom with easy refills: Classic 300S.

Pick the Levoit if…
- ✓Bedroom, nursery, or office
- ✓Top-fill convenience matters
- ✓You don't need warm mist and want to save money
