Quietest Air Purifiers UK
Noise is the #1 complaint about air purifiers. We measured real-world decibel levels to find options that clean air without disturbing your peace.
Noise Level Reference Guide
Understanding decibels: Every 10dB increase sounds roughly twice as loud to human ears.
For undisturbed sleep: Look for purifiers under 30dB on sleep/low mode. Most people can sleep through 35dB, but light sleepers need 25dB or less.

Tips for Quiet Operation
Run on high when you're out
Blast the room while you're at work, then switch to low/sleep mode when home.
Use sleep/night mode
Most purifiers have a quiet mode that reduces fan speed and dims lights for nighttime.
Oversized for quiet
A larger purifier on low speed can clean as much air as a smaller one on high - but much quieter.
Placement matters
Place on a solid surface away from walls. Vibrations against furniture increase perceived noise.
Check the dB curve
Some purifiers jump from 25dB to 50dB between speed 1 and 2. Look for gradual noise curves.
