The unit is also user-friendly, with a sleek design, touch controls, and a quiet operation mode (24dB) ideal for nighttime use. However, the need to use genuine Levoit replacement filters can be a drawback due to potential higher costs compared to off-brand options. Additionally, while it covers large areas, it is optimal for smaller spaces around 219 square feet for maximum efficiency.

Energy consumption is reasonable at 45W, and it is certified by Energy Star, ensuring it's an energy-efficient choice.
