Our Verdict

Vornado EVDC300

Levoit Superior Studio 450S

The Levoit Superior Studio 450S is a better humidifier overall than the Vornado EVDC300. Both are evaporative humidifiers with similar humidification capacities, which makes them suitable for larger bedrooms and living spaces. The Levoit is much easier to clean, though, with several dishwasher-safe components and a machine-washable wick that saves you from scrubbing everything by hand. It also has app support, so you can monitor humidity levels and adjust settings remotely, while the Vornado relies on physical controls. The Vornado's main advantage is its better energy efficiency, so it's worth considering if you want to minimize electricity consumption over long periods, though neither is likely to cause a big spike on your power bill.
