Noise level was a major strength at sleep and lower settings, though several reviewers noted max speed could be loud or merely average.

Cons: VOC sensor accuracy, handle design
Noise was one of the strongest positives: most reviewers called it quiet, especially on low, though a few found high speed distracting.
Pros: energy efficiency, power consumption
Cons: scheduling options, true HEPA filter
Noise opinions vary by speed: sleep and low are widely praised, while high speed is sometimes called loud or noisy.

Noise was praised on low settings and in quiet rooms, but reviewers noted louder high or max modes.
