🔊 Dyson Air Purifier Noise Levels — Decibel Comparison
See what Dyson air purifier noise levels actually sound like.
Dyson air purifiers are premium products with sleek designs, but they have a reputation for being louder than competitors at similar CADR ratings. This is partly because Dyson uses bladeless fan technology, which produces a different type of sound — more of a smooth whoosh than a mechanical hum.
Dyson's "Night mode" reduces fan speed and display brightness, typically dropping noise to 30–35 dB. But even on their lowest regular setting, Dyson purifiers tend to sit around 35–40 dB, which is noticeably louder than Coway or Levoit on low.
The newer Big Quiet series addresses this with larger, slower-spinning fans that produce less turbulence noise.
