Noise was a major strength across reviews, with most calling it quiet or virtually silent; one user still noticed slight buzzing.
Pros: air purification performance, noise level
Cons: activated carbon filter, HEPA filtration
Noise level is one of the strongest attributes at low settings and sleep use, though maximum speed drew some caveats.
Pros: noise level, air purification performance
Quiet operation is the product's standout strength, particularly on low or sleep settings. Complaints mostly involve higher-speed noise, isolated whines, or a newer unit that seemed louder.
Pros: overall satisfaction, room coverage
Cons: app connectivity, control placement
Noise was mostly praised at low or sleep settings, but some reviewers complained about top-speed loudness or buzzing.

Cons: activated carbon filter, ozone-free operation
Noise evidence was mixed by speed: low and night settings were often very quiet, while full power was repeatedly described as noticeably loud.

Cons: filter replacement cost
Noise depends heavily on mode: low, auto, and night are often quiet, while high speed or defective fans can be loud.

Cons: filter replacement cost, activated carbon filter
Low-speed and night-mode noise are often praised as nearly silent, but higher fan speeds and some defective or light-related sounds frustrate several users.
